How to Learn JQuery?
Within a few lines of code, it can execute complicated operations such as DOM manipulation.
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
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.
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.
