jquery sets text to element

jQuery is a very popular and powerful JavaScript library. It provides many convenient methods to manipulate HTML elements and the Document Object Model (DOM). One of the very useful features is setting the text of an element with jquery.

In this article, we will explore how to set the text of an element using jquery. We will introduce two methods: .text() and .html().

Method 1: .text()

.text() method is the most basic method used to set element text in jqury.

To use the .text() method, you can first select the element on which you want to set the text. For example, let's say you have the following HTML code:

<h1 id="myHeader">Welcome to my website</h1>

To change the text of the title element using the .text() method, use the following code:

$('#myHeader').text('Hello World!');

In the above code, we are using jQuery The selector ($()) selects the element with the id "myHeader" and uses the .text() method to set its text to "Hello World!".

Note: Using the .text() method will completely replace the text content of the element. This means that if the element originally had some text, it will be completely replaced. If you want to add rather than replace text, you should use the .html() method.

Method 2: .html()

.html() method is very similar to .text() method, but it can not only set the text of the element, but also set the HTML content of the element.

To use the .html() method, you select the element you want to set using the same method as the .text() method and set its HTML content using the following code:

$('#myHeader').html('<em>Hello World!</em>');

above In the code, we use the jQuery selector ($()) to select the element with the id "myHeader", and use the .html() method to set its HTML content to "Hello World!". This will display the "Hello World!" text with the emphasis tag in the element.

Please remember to be careful when using the .html() method. If you insert malicious code into HTML content, it will be executed in the user's browser. This can expose your site to security attacks. Therefore, you should avoid unnecessary HTML content and use text instead of HTML strings.
