Introduction of jQuery Attributes

jQuery is a library of JavaScript, which we can use in an html code. The need for jQuery in an html is to easy use JavaScript in that and to make a website more attractive and interactive. Actually, jQuery is a JavaScript toolkit which is having various built-in functions by writing less code, so the motto is “ write less, do more “. In this topic, we are going to learn about jQuery Attributes.

The various important features of jQuery are –

DOM manipulation– To select DOM elements and modify DOM elements content with open source cross-browser selector engine, which is called Sizzle, is made very easy by The jQuery.

AJAX Support– The AJAX (Asynchronous JavaScript and XML ) is used to render the website page; with the AJAX technology, we can create a responsive and feature-rich site. The jQuery helps to develop the AJAX technology in html code.

Animations− The various built-in animation effects provided by jQuery which can be use on websites.

Lightweight− The good feature of jQuery is it is lightweight. It is just 19KB in size.

Cross Browser Support− The cross-browser is another important feature of jQuery, which supports various browsers Chrome, IE 6.0+, FF 2.0+, Safari 3.0+, and Opera 9.0+.

Latest Technology− The latest technology, CSS3 selectors, basic XPath syntax, and so are supported by jQuery.

The prerequisites for jQuery Attributes –

How to Run JQuery Codes?

The jQuery can be written and run two ways as –

CDN Based Version− In this, we include the jQuery library into an HTML code. The jQuery include directly from CDN ( Content Delivery Network ).

Example #1

We write an HTML example program in which we include the jQuery library as in the below example −

<script type = “text/javascript” $(document).ready(function() { document.write(” Hello! from jQuery code “); });

The output of the above program is 

When the event is generated, all the code which is inside of the $(document) .ready () function is executed, or the entire component or in other word elements loaded before DOM.

Next, the basic components which we can modify when it comes to DOM elements are the properties and attributes of the elements assigned value. So let’s see how we can modify the attributes of the elements using jQuery.

Some of the element properties or attributes that are common uses based on the element are – className, title, tagName, id, rel, href, src, alt, align, id, and so all.

Let’s take the example of the html image element and its attribute −

The above element tag name is img, and the attributes are class, id, src, alt, and title; each attribute is assigned some value. These attributes value we can get and change by using jQuery. The jQuery provides two methods, attr()  and attr(name, value), to get the attribute value and to set the attribute value of a matched element, respectively.

The syntax of using the attr() method is different based on the purpose of use.

To get the value of an attribute –

$(element).attr(attribute);

To set the attribute and value –

$(element).attr(attribute, value);

To set attribute and value using a function –

$(element).attr(attribute, function(index, currentvalue));

To set multiple attributes and values –

$(element).attr({attribute : value, attribute : value, attribute : value });

To get the Attribute Value of a matched elements –

We can get the attribute value of an element by using the function attr(attribute) from the first element in the matched set or set attribute values onto all matched elements.

Example

Example #2

<script type = “text/javascript” $(document).ready(function() { var title = $(“h1”).attr(“title”); $(“#id_div”).text(title); });

The output of the above program is 

Example #3

<script type = “text/javascript” $(document).ready(function() { var id = $(“h2”).attr(“id”); $(“#id_div”).text(id); });

To set the Attribute Value of matched elements –

We can set the attribute value of an element by using the function attr(attribute, value) onto all elements in the matched set or set attribute values by using the passes value.

Consider an example which set the src attribute of an image tag to a correct location −

Example #4

<script type = “text/javascript” $(document).ready(function() { $(“#imgid”).attr(“src”, “altimage.png”); });

The output of the above program is 

Example #5

<script type = “text/javascript” $(document).ready(function() { $(“h1”).attr(“align”, “center”); }); });

The output of the above program is 

Next, we see how to apply different styles to the matched elements using jQuery-provided method addClass(classes). We can apply not only a single style class but can apply multiple classes just separated by space.

Example #6

<script type = “text/javascript” .font { color : green; } .highlighht { background : yellow; } $(document).ready(function() { $(“h1”).addClass(“font”); $(“#h2id”).addClass(“highlighht”); });

The output of the above program is 

Example #7

<script type = “text/javascript” .font { color : green; } .highlighht { background : yellow; } $(document).ready(function() { $(“h1”).addClass(“font”); $(“h1”).attr(“align”, “center”); $(“#h2id”).addClass(“highlighht”); });

The output of the above program is –

Attribute Methods of jQuery

Some of the jQuery attribute methods which modify the DOM elements attributes and properties are –

attr( properties ) – This method sets attribute value to all matched elements. Above, we have seen an example of this; now we see this method to set multiple key-value properties.

Ex : $( "img" ).attr({ alt : " Image not available", src : "img.png", title : "Image jQuery"});

attr( key, fn ) – This method sets a single attribute or property to a value on all matched elements.

Ex : $("h1").attr("align", "center");

removeAttr( name ) – This jQuery method is used to remove an attribute from all matched elements.

Ex : $("h1"). removeAttr ("align", "center");

hasClass( class ) – This jQuery method used to find a specified CSS class is applied on any one of the matched elements; if yes, then it returns true otherwise false.

Ex : $("p#ptagid"). hasClass ("font ");

addClass( class ) – This jQuery method used on elements to apply the specified class if it is not applied.

Ex : $("h1").addClass("font");

removeClass( class ) – This jQuery method used on elements to removes specified classes or classes.

Ex : $("p#ptagid"). removeClass ("font ");

html( ) – This jQuery method used to get first html tag or matched element.

Ex : $("h1").html( );

text( ) – This jQuery method used to get the text contents of all matched elements, except form and input elements.

Ex : $("#id_div").text(title);

val( ) – This jQuery method used to get the value of input from the first matched element.

Ex : $("#inputid").val( ); Conclusion – jQuery Attributes

jQuery is a JavaScript library. jQuery allows performing tasks such as DOM manipulation, event handling, AJAX Support, Animations, Lightweight, Cross Browser Support, Latest Technology. Use jQuery in html code two ways: Local Installation, and another way is CDN Based Version.

The DOM element attributes such as className, title, tagName, id, rel, href, src, alt, align, id and all can be fetch and set by using the jQuery provided method attr()  and attr(name, value), respectively.

The different jQuery method is

attr( properties )

attr( key, fn )

removeAttr( name )

removeClass( class )

toggleClass( class )

html( )

val( )

How To Fix Netflix Error Codes B33

In today’s post, we will identify some potential known causes that can trigger the Netflix app error codes B33-S6 and UI-113, as well as provide the possible solutions you can try to help remediate the issue as it relates to either of the error codes.

Netflix error code B33-S6

You may encounter the Netflix error code B33-S6 when you try to login to the Netflix app or try to use the Netflix app.

We’re sorry, but an unexpected error was encountered.

We are aware of this issue and are working to resolve it. Please try again later. If the problem doesn’t go away soon, contact Netflix customer service.

Error code: B33-S6

When the error code is displayed, it will either force close the app or won’t let you use the app.

The error is displayed because of two issues. The first is because of poor or no network connectivity. The second reason might be because of an issue in stored information or issue with the settings of the app.

If you’re faced with the Netflix error code B33-S6, you can try either of the our two recommended solutions below in no particular order and see if that helps to resolve the issue.

Check the network connection

Uninstall and reinstall Netflix

Let’s take a look at the description of the process involved in relation to each of the listed solutions.

1] Check the network connection

To check your network connection to determine if you can’t access the internet or you are having trouble in network connectivity, do the following:

Locate your internet modem/router.

Disconnect the power cable of the modem/router.

Now, wait 5 minutes.

Reconnect the power cable and make sure the modem/router is turned on.

Now check if the network connection is working. If you are still experiencing problems in the network then contact your network provider.

If your network isn’t the issue but the Netflix error code B33-S6 persists, then continue with the next solution.

2] Uninstall and reinstall Netflix

The error code B33-S6 can be caused by the problem in stored information and settings of the Netflix app. Since there is a problem in the app files and settings, simply uninstalling and reinstalling the Netflix app will solve the problem.

To uninstall and reinstall the Netflix app, do the following:

Note: Uninstalling the app will delete the titles that you have downloaded.

Uninstall instructions

Press Windows key + R to open up a Run dialog box.

Next, type ms-settings:appsfeatures and press Enter to open up the Apps & Features tab of the Settings app.

Next, locate the Netflix app on the right side of the Apps & Features window.

Once the operation is complete, reboot your computer and wait for the next startup to complete.

After the next startup is complete, continue as follows:

Press Windows key + R to open up another Run dialog box.

Now type ms-windows-store://home and press Enter to open up the Microsoft Store.

Next, use the Microsoft Store’s search function (top-right section of the screen) to search for Netflix.

Once the application is installed again, launch Netflix UWP again and see if the error is resolved.

Netflix error code UI-113

This may be caused by problems with your home network, interrupted Internet connection, corrupt cached app data on your streaming device. It may also appear if the Netflix service itself has failed.

When you encounter Netflix error Code UI-113, you will normally receive the following message:

Code: ui-113

If you’re faced with the Netflix error code UI-113, you can try our recommended solutions below in no particular order and see if that helps to resolve the issue.

Try accessing Netflix via a web browser

Restart your streaming device

Restart your router/modem

Disconnect any VPN and Proxy connection

Sign out from Netflix and sign back in

Clear the Netflix app cache on your device

Uninstall and reinstall Netflix app

Let’s take a look at the description of the process involved in relation to each of the listed solutions.

1] Try accessing Netflix via a web browser 2] Restart your streaming device

It’s possible the device you’re using to stream contents on Netflix could be causing the error code UI-113. There might be some bug or some loading problem with it that might be preventing it from connecting to the internet. In this case, do the following:

Unplug the power to your Streaming Device.

Now, wait for 5 minutes.

Plug in your device and see if Netflix works.

If the issue persists, continue with the next solution.

3] Restart your router/modem

It is also possible that there might be a configuration issue with the internet modem/router that you are using. In this case, you can try power cycling the internet device. Here’s how:

Unplug the power to your internet device.

Now, wait for at least 5 minutes.

Plug in the modem/router and wait for the connectivity light to start blinking.

Afterwards, launch the Netflix app and see if the error code UI-113 is resolved. If not, continue with the next solution.

4] Disconnect any VPN and Proxy connection

If you are connected to the Internet via a virtual private network or proxy server, you can try to disconnect and connect directly to the Internet. Sometimes, the device will have problems connecting to the Internet if you are connected to another server. The device may not be able to contact the streaming services so in this case, disconnecting all VPN and proxy connection could resolve the Netflix error code UI-113.

5] Sign out from Netflix and sign back in

To sign our and sign back in, do the following;

Head to Netflix account page.

Go to the Settings option.

Select Sign Out Of all devices.

This will sign Netflix out of all the devices you use Netflix on.

Sign in again to the device.

Launch the Netflix app and see if the error code UI-113 is resolved. If not proceed with the next solution.

7] Uninstall and reinstall Netflix app

If the problem still persists then it should be with the Netflix app itself. In this case, uninstalling and reinstalling the app on your device could fix the error code UI-113.

If none of the troubleshooting steps outlined in this post for Netflix error code B33-S6 and UI-113 doesn’t help you, you may need to contact your device manufacturer, Internet service provider or Netflix for assistance.

How To Use .On And .Hover In Jquery?

jQuery- a popular JavaScript library used in simplifying web development tasks. It gives an easy-to-use syntax that simplifies coding and improves performance. Among the many features that jQuery provides, two of the most commonly used are .on() and .hover(). These methods allow to bind events to DOM elements and executing code when the events are triggered.

In this article, we will learn how to use .on() and .hover() in jQuery. We will see the different approaches to using the .on() and .hover() methods.

The .on() Method

The .on() method in jQuery is used in binding one or more events to a selected element. The method provides a flexible way to attach events to existing and dynamically created elements. The .on() method gives a lot of consistency to the API, and is recommended to use this method due to its simplifying process in the jQuery code base.

Syntax

Below is the syntax for using the .on() method in jQuery.

$(selector).on(event, childSelector, data, handler); Parameters

selector − the selector of the element(s) to which the event will be bound.

event − the event(s) to be bound to the selected element(s).

childSelector (optional) − a selector for child elements of the selected element(s) that should trigger the event.

data (optional) − additional data to pass to the event handler function.

handler − the function to be executed when the event is triggered.

$(document).ready(function() { }); });

Example 2: Binding Events to Dynamic Elements

The .on() method binds a blur event to the form on the page. This event is triggered when an input field loses focus. We specify the “input” selector as the second argument to the .on() method, which tells jQuery to only listen for blur events on input elements that are descendants of the form element. When a blur event is triggered, we use the $(this) keyword to get a reference to the input field that triggered the event, and use the .val() method to get its value. We then display the value in an alert box.

$(document).ready(function() { $(“form”).append(input); }); $(“form”).on(“blur”, “input”, function() { alert($(this).val()); }); });

Event Binding in .on() Method The .hover() Method

The .hover() method in jQuery is used in binding two events i.e. mouseenter and mouseleave event to a selected element. This method allows us to execute different codes when the user hovers over an element and when they move their mouse away from it.

The hover() method specifies two functions to run when the mouse pointer hovers over the selected elements.

Syntax

Below is the syntax for using the .hover() method in jQuery.

$(selector).hover(handlerIn, handlerOut); Parameters

selector − the selector of the element(s) to which the event will be bound.

handlerIn − the function to be executed when the user hovers over the element.

handlerOut − the function to be executed when the user moves their mouse away from the element.

Example: The Default Method

In the below example, we have used the $(document).ready() method to wait for the DOM to be fully loaded before executing the JavaScript code and also used the .hover() method to bind two events (mouseenter and mouseleave) to the div element on the page. Now, when the user hovers over the div, the background color is changed to violet using the .css() method. When the user moves their mouse away from the div, the background color is changed back to green.

div { width: 200px; height: 200px; background-color: green; border: 1px solid black; } $(document).ready(function() { $(“div”).hover(function() { $(this).css(“background-color”, “violet “); }, function() { $(this).css(“background-color”, “green”); }); });

Conclusion

The .on() and .hover() methods in jQuery are powerful tools that make it easier to bind events to DOM elements and execute code when those events are triggered. The .on() method provides a flexible way to attach events to existing and dynamically created elements, and the .hover() method allows us to execute different codes when the user hovers over an element and then moves their mouse away from it. By understanding the syntax and different approaches to use these methods, developers can create more dynamic and interactive web applications with ease.

Working Of Jquery Reference In Jquery With Examples

Definition of jQuery Reference

In Jquery, reference is defined as a set provided by jquery which contains jquery events used for triggering methods, selectors, and properties, which are defined for selecting and converting HTML elements provided few methods for handling events for such selections which when the events are triggered when the methods are executed and this jquery reference have the ability where to make the navigation (top, down, right and left) of the HTML elements along with supporting of jquery effects such as sliding or fading or showing or any kind of animations in the web pages using HTML elements are all defined and are provided by the jquery reference in Jquery.

Working of Reference in jQuery Examples

In the below section let us take one by one element of the jquery reference that contains methods, events, effects, selectors, utilities, etc along with examples:

Events Example

Code:

#circle { width: 150px; height: 150px; border-radius: 50%; background-color: green; margin: 200px 200px 200px 200px; } });

Output:

jQuery Reference manipulation methods Example

Code:

$(document).ready(function () { $(‘p’).append(‘Educba ‘); }); div{ border: 2px solid; background-color:blue; margin: 5px 0 5px 0; font-size:20px; }

Output:

In the above program, we can see we are using append(), prepend(), after(), and before() method where we have added the content after the h1 element which shown in cyan color, then we are adding content before second div tag which is shown in yellow color, then we add the content at beginning of the paragraph which gives prepended paragraph and then the paragraph content is appended with the word “Educba” and prints complete sentence “Welcome to Educba”. There are many such methods used for constructing such web pages.

Selectors

In jquery, it provides the main function which is used only when we are using jquery codes as we know before writing jquery code we start with $ symbol so this is called as factory function which has the syntax as “$()” where we can pass any name or element name, id, class, etc of tags that are defined in the HTML structure.

Example

Code:

<script type = “text/javascript” #circle { width: 150px; height: 150px; border-radius: 50%; background-color: green; margin: 10px; } .educbaclass { margin:50px; border :10px solid; } }); $(“p”).css(“background-color”, “yellow”);

In the above program, we can see we have declared a div tag and defined with id name as “circle” so we are using the selector on div tags which has id. Similarly, we have also defined a class name for paragraph “p” and we can see in the above code we are printing that selected paragraph with different CSS styles which can be done not only by the CSS syntax in HTML structure but also using jquery selector and function CSS() on paragraph tag. Therefore there are many such selectors that are used in jquery reference such as selecting multiple elements, selecting all the elements of DOM using universal selector, etc.

In jquery reference, there are effects which are used for animation effects in web pages such as animate(), fadIn(), fadeout(), hide(), show(), etc. In traversing reference can be used for movement of elements such as up, down, right, left, etc.

Learn How To Code And Program

From 7-22 October 2023 it’s EU Coding Week (the astute among you will note this is in fact two weeks) and this makes it is an ideal time to learn to code. You can find out more on the  codeweek.eu website and you can check Apple’s website as there will be free coding sessions at Apple stores for the same period (with thousands to follow over the next six months).

What language should you learn?

With so many different programming languages and, indeed, types of programming, the first consideration is which languages you should invest your time and effort in learning.

Do you want to create apps for smartphones and tablets? Would you like to design and build websites? There’s even the programming of the embedded computers which are built into everything from your TV to your car. Each area requires radically different code, so while we can’t decide which is best for you, we’ll explain where to start looking.

If you expect to be learning to code in full-time education, there’s a good case for working with the languages most commonly used in schools. Alternatively, for those who hope to employ their coding skills in the workplace, we’ll give some thought to which languages are used in industry for various applications.

Just knowing which languages to learn isn’t enough, though. So we’ll also provide some guidance on what software you need in order to learn each language and which resources and courses will help you in your quest.

Resources for kids and teens

There are a few tools specifically aimed at helping young people get into coding. One is the BBC micro:bit, which is being given to students in Year 7 for free, but which you can also buy for £15. You can code for it using a variety of tools and languages including MicroPython and JavaScript.

There are also plenty of coding games and toys for kids, ranging from kid-friendly DIY computer kits like the Kano to programmable robots like the Sphero SPRK+. These generally build games into the way they teach coding to help keep kids entertained as they learn.

Another option is Apple’s Swift programming language. Apple has released a  free iPad app called Swift Playgrounds which aims to teach kids to code in Swift using a fun game-like environment. It works on all iPad Air and Pro models, the regular iPad from 2023, plus iPad mini 2 and later. They will also need to be running iOS 10 or later.

Programming by blocks

One of the two most commonly used programming languages in schools is Scratch, which was developed by the Lifelong Kindergarten Group at the MIT Media Lab. Unlike most languages, Scratch programs are created by linking blocks together on screen.

This allows students to learn about the structure of programs and the concept of algorithms but without having to learn syntax, that is the exact textual format of an instruction in a conventional language. In addition, because the blocks resemble jigsaw pieces, their shapes reduce the likelihood of blocks being connected together when the end result would be nonsensical.

Despite this unconventional approach, Scratch genuinely is a procedural language, as are most of the popular computer languages. In other words, it allows the programmer to define a sequence of operations for the computer to carry out.

Scratch is often used in primary schools but it would be unwise to set an upper age limit, above which a student should learn a conventional language instead. It’s also used in secondary schools, indeed it could be beneficial for anyone who has never coded before, while recognising that it will always be a stepping stone to the types of language that are used in business and industry.

Scratch is available free of charge. You can either download a version to use offline or you can create programs directly on the website.

Another block-based language that is gaining popularity is Google Blockly – see our guide to getting started with Blockly. The BBC micro:bit also uses a block-based programming environment called Microsoft Block Editor.

The BASIC alternative

When there was last a big push on teaching computing in schools, BASIC was the language of choice since it was available on the BBC Micro as well as on many of the cheaper home computers of the time. Although it was designed as an educational language, though, BASIC’s continued use for learning to programme is the subject of some debate.

Some would argue that it’s an old-fashioned language that will get students into habits they’ll find it hard to break when they start to learn newer languages. Others say that, because it’s such a simple language, it better illustrates the way processors work than more modern languages and is useful because it provides this insight.

Pragmatically, BASIC is still taught in schools quite extensively because it’s more familiar to a large number of teachers. What’s more, in contrast to the “bad habits” argument, there are suggestions that it’s useful to learn different programming paradigms, something that studying newer languages alone won’t provide. All of this seems to suggest that BASIC is still a good language to learn, at least as part of the mix.

In its 50 years, BASIC has spawned a huge number of dialects. Newer versions of BASIC include concepts such as block structure and object orientation but there’s a lot to be said for sticking with a version that is true to its roots.

For a fairly basic BASIC, but with extensions to carry out graphics programming, SmallBASIC (not the same as another variant of the same name published by Microsoft) would be a good choice – it’s freely available from http://smallbasic.sourceforge.net.

Note that Microsoft’s Visual Basic (formerly called Visual Basic .NET and commonly still referred to as such), is very different from BASIC of old. Indeed the current version of Visual Basic is object oriented (which we’ll explain in the next section) and is another possible contender if you want to learn this type of language.

Object-oriented languages

The second of today’s most popular languages in education is Python. Unlike BASIC, this adheres to current thinking in programming such as block structure and object orientation. As such, it’s similar to C++ and C# which are widely used in industry (together with their predecessor C), although Python is generally considered as easier to learn.

We’re not going to delve into exactly what object orientation actually means – after all that will be something you’d become familiar with if you were to learn Python – but suffice to say that expertise in this type of language would be a very useful skill. You can download a Python interpreter from

If you’re interested in learning Python, there are numerous online courses available including the Complete Python Bootcamp and The Complete Python Developer Course.

With the explosive growth in the uptake of Android smartphones and tablets, it would be quite natural to want to learn to create your own Android apps, a large majority of which are written in Java (not the same as JavaScript, which we discuss later). In addition, Android’s popularity means that learning this language could be a good move from the viewpoint of career prospects.

This is another object-orientated language so would be a logical progression from Python or, if you don’t fancy learning two similar languages, an alternative to Python, albeit one that’s not as commonly used in schools. If you want to learn Java you have several options. The  Java Development Kit (JDK) is freely available and runs on your PC.

However, if you specifically want to try your hand at Android app development, you’ll need Android Studio and, in addition to the Java language, you’ll need to learn about the Android environment. You can

Most of today’s most popular languages are object-oriented. Although the syntax varies between the different languages, having learned one such language you’ll be in a good position to migrate to another. If you want to discover which are the most commonly used in industry today, take a look at the Ttiobe index. 

Web programming – HTML and CSS

Coding for the web is very different from everything we’ve seen so far since, at its most basic, it uses a completely different type of language. Even so, it’s a vital skill to learn.

To create the simplest of web pages you’d use a language called HTML (and ideally the latest version, HTML5) which stands for HyperText Markup Language. As a markup language, it doesn’t provide a list of instruction that are executed in sequence as procedural languages do but, instead, it describes how text and images are displayed on screen.

This is just a simple example and it gets more involved when you start to add graphics, tables and links, but the concept of tags applies throughout.

Most web browsers will allow you to see the HTML source code that generated the page you’re viewing. However, going beyond this, dedicated HTML editors (e.g. CoffeeCup Free HTML Editor from

In addition to writing HTML code, unless you’re working as part of a multi-disciplinary team, you’ll also need some graphics design skills. While we need to mention this to present the full picture, it would be stretching a point to refer to this aspect of web design as coding.

A webpage created using HTML alone will be static, but other languages allow you to create dynamic content. The very first step in this direction is the use of another language called CSS which stands for Cascaded Style Sheets.

We’ve seen how text can be turned into a header in HTML and, in the simplest of cases, the browser will use its own default font, size and colour for each level of heading. HTML does allow you to define these characteristics yourself but CSS provides a better way.

A separate CSS file defines exactly how each of the heading levels appears, making it easy to alter the appearance of an HTML document purely by specifying a different CSS file. Using a CSS file, every page on a company website can be given the same corporate look and feel without having to repeat the formatting information in every single HTML file.

The next stage in making web pages dynamic is to add code that responds to the user’s actions. This sort of dynamic code is executed, for example, when you login to a website.

While we’re not going to get too involved in this here, it’s important to recognise that this involves the use of procedural languages, i.e. the ones that define sequences of instructions, rather than markup languages like HTML or style sheet languages like CSS. In particular, a language called JavaScript (which is quite different to Java that we looked at earlier) is often used to define code that runs in the browser while PHP is used to define code that runs on the remote server that hosts your website.

There are hundreds of online HTML courses, including Build Responsive Real World Websites with HTML 5 and CSS3, Learn to Build Beautiful HTML5 and CSS3 Websites in One Month, and Learn Web Designing & HTML 5/CSS3 Essentials in Four Hours.

Learning Resources

You don’t have to go it alone if you want to learn to code as there’s plenty of help out there. Many would-be programmers will already be learning to code at school, college or university but there are plenty of resources, either for those not in full-time education, or for those who want to augment their formal education.

The most easily accessible are the myriad online programming courses for just about any modern language you could imagine. As well as Googling for your preferred language, be sure to take a look at Codecademy. You should also check out Udemy, which has a broad range of online courses including plenty for coding.

Also look at adult education courses at your local colleges because being able to interact with a lecturer and chat with other students makes the learning experience so much easier. While some colleges only provide courses on using computers and software, some do offer evening programming courses at reasonable prices.

A concept that can benefit students in primary and secondary schools is the coding club. These are free, independent programming clubs for young people, that are led by volunteers and often sponsored by industry, that aim to supplement the teaching given in class.

Take a look at The Code Club and CoderDojo, both of which tend to concentrate on the languages most used in schools, and  Apps for Good that teaches young people to create apps.

How To Create Mini Theme Flip Toggle Switch Using Jquery Mobile?

In this article, we will explore the process of creating a Mini Theme flip toggle switch using jQuery Mobile. This type of toggle switch is a user-friendly way to present a binary option to the user, allowing them to quickly switch between two options. jQuery Mobile provides a simple and efficient way to create this type of control, making it easy to implement and customize. By the end of this article, you will have a working Mini Theme flip toggle switch that you can use in your own web applications.

Getting Started with jQuery Mobile

Before we dive into the process of creating a flip toggle switch, you need to make sure you have the jQuery Mobile library included in your project. You can download it from the official website or include it from a CDN.

Syntax $(selector).slider(options) .slider() Method

The slider() method, which is a part of the jQuery Mobile library, is utilized to generate a slider control that allows the selection of a value from a range of values. This slider control is constructed from a select element that specifies the range of values with option elements. The slider() method can be applied to alter the slider’s appearance and behavior, such as defining the minimum and maximum values, step size, and orientation. Furthermore, the slider() method provides the ability to attach events to the slider to respond to changes in the chosen value or monitor the slider handle’s movement.

Where −

selector is a string containing a selector expression that matches the select element(s) to be converted into a slider.

options is an optional object that can be used to specify the options for the slider.

The options available for the slider() method are −

disabled − a boolean value that determines whether the slider is disabled or not.

initSelector − a string containing a selector expression that matches the select elements that should be automatically converted into sliders.

mini − a boolean value that determines whether the slider should use the mini version of the jQuery Mobile theme or not.

theme − a string that specifies the theme to be used for the slider.

trackTheme − a string that specifies the theme to be used for the track of the slider.

highlight − a boolean value that determines whether the slider should highlight when the handle is moved.

step − a number that specifies the size of the step interval to be used when selecting values.

Approach

Creating a Mini Theme flip toggle switch using jQuery Mobile involves the following steps −

Include the jQuery Mobile library in your HTML file. This undertaking can be achieved through two methods – the first being the addition of a reference to the library in the head segment of the HTML document, while the second involves obtaining the library and assimilating it into your project.

Constitute a select component in your HTML document and supplement a duo of alternative components to it. The primary alternative component will embody the “inactive” orientation of the switching mechanism, whilst the secondary alternative component will epitomize the “active” orientation of the switching mechanism.

Call the slider() method on the select element. The slider() method will convert the select element into a slider control, which can be used as a toggle switch.

Incorporate the data-role characteristic onto the select element and establish its worth as “slider”. Such action notifies jQuery Mobile to fashion the select element as a slider mechanism.

Set the data-mini attribute to “true” on the select element. This tells jQuery Mobile that the slider control should use the mini version of the theme, which is smaller in size and more suitable for mobile devices.

Incorporate the attribute of data-theme into the elect component and assign its worth to the coveted motif. This shall intimate jQuery Mobile as to which design to apply towards the management of the slider.

Incorporate the data-track-theme characteristic into the designated selection unit and establish its numerical or categorical denomination to the preferred motif for the trail of the slip controller.

Electively, append the data-highlight characteristic to the elect component and designate its worth to “true” if you yearn for the slide regulator to accentuate whilst the grip is shifted.

Finally, bind an event handler to the slider event of the select element. The slider occurrence is activated upon any modification in the magnitude of the slider restraint. Within the happening handler, you have the ability to retrieve the present magnitude of the slider control and undertake operations in accordance with the elected magnitude.

Example

The following is the complete code which we are going to have a look at in this example −

$(document).ready(function() { $(“#flip-min”).slider(); });

Conclusion

To sum up, the fabrication of a Mini Theme flip toggle switch using jQuery Mobile is an uncomplicated and effortless undertaking. By utilization of the offered slider element from the library, we achieved the creation of an amicable toggle switch with just a small number of lines of code. Its Mini Theme layout makes it compressed and aesthetically pleasing, rendering it a magnificent option for web applications with limited screen space. As a result of its simplistic implementation and adaptable attributes, the Mini Theme flip toggle switch is a magnificent supplement to any web application. I trust that this article has served as a beneficial tutorial for the incorporation of this practical mechanism in your personal undertakings.
