JQuery is a JavaScript library that makes it easier for developers to write JavaScript code. In the process of using JQuery, we often need to delete some page elements or clear the content of some elements. This article will introduce how to use JQuery to delete or clear all content of the page.

Step one: Introduce the JQuery library

Before using JQuery, we need to introduce the JQuery library first. You can do this by following the steps below.

Add the following code in your HTML document:

<head>
     <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>

Copy after login

With this code, we have introduced the JQuery library from JQuery’s official website. Note that you can change this URL to reference your local jQuery library.

Step Two: Delete All Content

Now, let’s proceed with deleting the entire page’s content. To do this, follow the steps below.

Understanding the target element

We need to find the page element we want to delete. Usually, we will select the body element to delete the entire page content. So, we can use the following code:

$("body")

Copy after login

Delete Element

Now, we use JQuery’s empty() method to delete everything. The ready() method ensures that the page elements are loaded before executing this method. Here is the code:

$(document).ready(function(){
     $("body").empty();
});

Copy after login

Step 3: Clear all content

Suppose you don't want to delete the entire page's content, but just want to clear a specific element (such as a div). In order to do this, follow the steps below.

Find the target element

In this example, we will consider clearing a div element with a class of "myDiv". We can select the element using the following code:

$(".myDiv")

Copy after login

Clear the element

We now clear the div element using JQuery's html() method. Here is the code:

$(document).ready(function(){
     $(".myDiv").html("");
});

Copy after login

In short, through JQuery, we can easily delete or clear all page content or specific elements. If you are using JQuery, these codes will serve your purpose very quickly and easily.
