How to Learn JQuery?

JQuery is simple to learn and can be mastered in hours. However, it is generally advised that you have a fundamental understanding of HTML, CSS, and JavaScript before diving into JQuery. JQuery is nothing more than a JS library. In layman’s terms, it has four primary applications. These are some examples:

It significantly reduces the length of JavaScript code. It can accomplish the same thing in two lines that JavaScript does in 6-7.

Within a few lines of code, it can execute complicated operations such as DOM manipulation.

Compared to simple JavaScript, event handling is a piece of cake with JQuery.

It greatly simplifies AJAX calls.

Rather than going over the theory, a newbie should get in and practice things like evaluating the numerous functions JQuery provides and its performance. Let’s look at four actions you can do right now to get started with JQuery.

Step 1: Incorporate a JQuery Library

We’ve already spoken about utilizing the JQuery library in our HTML files. There are two methods to accomplish this: downloading the JQuery JavaScript file directly from the website and adding it using the script tags or utilizing a CDN such as Google to link to the library.

Using a CDN is a superior option since it loads things faster than downloading and hosting them on our server. It also minimizes the number of files in the project.

Step 2: Using JQuery to handle events.

With JQuery, you can simply create events such as button clicks, mouse in, focus, key presses, and so on.

The button click event is inserted within the function in the preceding code. This instructs the server first completely to load the page; after that, a function is run, showing the alert message when the button is pressed.

Step 3: JQuery DOM Manipulation.

Making DOM manipulation with JavaScript is a difficult process. JQuery, on the other hand, makes it a piece of cake. Take a look at a basic example.

Assume you have a list of five states presented as radio buttons. When a user picks the correct capital of the United States, the message “Correct” appears. When he picks the incorrect state, the notification “Wrong” appears. We can accomplish this by including a click event with the radio button.

In the preceding example, we compare the value of the radio button clicked to the correct response. We then located the button’s parent list element and inserted a paragraph tag with some CSS and relevant content.

Step 3: JQuery AJAX 

We may use JQuery to quickly execute server-side routines via AJAX queries and display the returned data on the HTML page. We can even use AJAX and JQuery to query our database using partial postback.

All four of the above steps are sufficient to get you started with JQuery. Once you’ve mastered these techniques, you may advance to learning how to optimize your code for improved performance.
