5. Sample jQuery Developer Interview Questions and Answers

Explore these sample questions with detailed answers to assess candidates’ jQuery skills:

Q1. Explain the key differences between jQuery and JavaScript.


jQuery is a JavaScript library that simplifies common tasks like DOM manipulation and event handling. JavaScript is a scripting language used for creating dynamic content and interactions on web pages.

Q2. How does event delegation work in jQuery, and why is it beneficial?


Event delegation in jQuery involves attaching a single event listener to a common ancestor of multiple elements. It’s beneficial for dynamically added elements as it ensures events are captured without the need to rebind them.

Q3. Implement a jQuery function that toggles the visibility of an HTML element with the ID “myElement” when a button is clicked.


<!-- Sample Answer: HTML and jQuery toggle function -->

<button id="toggleButton">Toggle Visibility</button>

<div id="myElement">Content to Toggle</div>


$(document).ready(function() {

 $('#toggleButton').on('click', function() {






Q4. Describe the purpose of the jQuery AJAX function and provide an example of using it.


The jQuery AJAX function is used for making asynchronous HTTP requests. Example:

// Sample Answer: jQuery AJAX request


 url: 'https://api.example.com/data',

 method: 'GET',

 success: function(data) {

 console.log('Data retrieved:', data);


 error: function(error) {

 console.error('Error:', error);




Q5. How does event bubbling work, and how can it be prevented in jQuery?


Event bubbling is the propagation of an event from the target element up the DOM hierarchy. It can be stopped using event.stopPropagation() in jQuery.

Q6. Write a jQuery function that fades out a list item when it is clicked.


<!-- Sample Answer: HTML and jQuery fadeOut function -->


 <li>Item 1</li>

 <li>Item 2</li>

 <li>Item 3</li>



$(document).ready(function() {

 $('li').on('click', function() {






Q7. Explain the concept of method chaining in jQuery.


Method chaining in jQuery involves calling multiple methods on a single jQuery object in a single line. It enhances code readability and reduces the need for intermediate variables.

Q8. How does the $(document).ready() function work in jQuery?


$(document).ready() ensures that the code inside the function is executed only when the DOM is fully loaded.

Q9. Write a jQuery animation that moves an element with the ID “animateMe” 200 pixels to the right.


<!-- Sample Answer: HTML and jQuery animate function -->

<div id="animateMe" style="position: relative; left: 0;">Animate Me</div>


$(document).ready(function() {

 $('#animateMe').animate({ left: '+=200px' }, 'slow');




Q10. How can you dynamically create elements using jQuery?


New elements can be dynamically created using the $(html) method. Example:

// Sample Answer: Creating a new div element

var newDiv = $('<div>', {

 id: 'newElement',

 text: 'This is a new element'
