FAQs on jQuery and AJAX Tutorials 21 - Adding Overlay and Frame Video Lecture - AJAX and jQuery: Complete Series for Beginners - Front-End Programming

1. What is jQuery?
Ans. jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, and animation much simpler with an easy-to-use API that works across a multitude of browsers.
2. What is AJAX?
Ans. AJAX stands for Asynchronous JavaScript And XML. It is a technique used in web development to create asynchronous web applications. With AJAX, you can send and retrieve data from a server asynchronously without interfering with the display and behavior of the existing page.
3. How can I add an overlay to my web page using jQuery?
Ans. To add an overlay to a web page using jQuery, you can create a new HTML element (such as a `<div>`) with a CSS class that styles it as an overlay. Then, you can use jQuery's `.append()` or `.appendTo()` method to add the overlay element to the desired container on your web page. Finally, you can use CSS to position the overlay and adjust its appearance as needed.
4. How can I create a frame in the front-end using jQuery?
Ans. To create a frame in the front-end using jQuery, you can use HTML and CSS to define a container element that represents the frame. Then, you can use jQuery to dynamically populate the frame with content. This can be done by using jQuery's `.html()` or `.append()` method to add HTML content to the frame container. Additionally, you can use CSS to style the frame and apply any desired visual effects.
5. Can I use jQuery and AJAX together?
Ans. Yes, jQuery and AJAX can be used together. In fact, jQuery provides convenient methods for making AJAX requests, such as `$.ajax()` and `$.get()`, that simplify the process of sending and retrieving data from a server asynchronously. These methods handle many of the underlying details of AJAX, making it easier to incorporate AJAX functionality into your web applications.
