How To Get Id In Jquery

If you’re new to jQuery, you may be wondering how to easily and effectively access and manipulate the IDs of various elements within your web pages. In this blog post, we’ll guide you through the process of getting the ID of an element using jQuery, whether it’s for selecting, modifying, or otherwise interacting with the element in question.


Before diving into the examples and explanations, ensure that you have added the jQuery library to your project. You can either download it from the jQuery website or include it via a Content Delivery Network (CDN) like Google or Microsoft. For example:

    <script src=""></script>

Selecting an Element by ID

To get an element by its ID using jQuery, you can use the familiar CSS syntax for IDs combined with the jQuery $() function. For example, if you have an element with the ID “myElement” and you want to select it using jQuery, you would do the following:

    var element = $('#myElement');

This code snippet assigns the jQuery object for the element with the ID “myElement” to the variable element. You can then use this variable to perform various jQuery operations on the selected element.

Getting the ID of an Element

Now that you know how to select an element by its ID, you may also want to retrieve the ID of an element as a string. To do this, simply use the attr() function, like so:

    var elementId = $('#myElement').attr('id');

This code snippet gets the ID attribute of the selected element and assigns it as a string to the variable elementId.

Working with Dynamically Generated Elements

When working with elements that are generated dynamically (e.g., through user input or AJAX), you may not know their IDs ahead of time. In such cases, you can use event delegation to bind events to these elements, then use the this keyword to refer to the element that triggered the event:

    $('body').on('click', '.dynamicElement', function() {
        var elementId = $(this).attr('id');
        console.log('Clicked element ID:', elementId);

In this example, we’re binding a click event to elements with the class “dynamicElement” that may be added to the page dynamically. When one of these elements is clicked, the event handler function is called, and the this keyword refers to the clicked element. We can then use the attr() function to retrieve the ID of the clicked element.


Getting and working with IDs in jQuery is quite simple and straightforward once you’re familiar with the basic syntax and methods. With this guide, you should now be able to confidently select elements by ID, retrieve their IDs, and handle events for dynamically generated elements with ease. Happy coding!
