How to Replace String, Text or HTML in jQuery?

The replace() function is a jQuery function that can be used to replace elements that have been declared by the end-user. Each element is a set of matched elements that will be provided with new contents. It returns the set of elements that have not been removed by the end-user as well as only the removed elements.

These replace() methods have a few child methods, such as replaceAll() and replaceWith(). These replacements will be done by integrating target elements with the set of achieved items on the list, which might be a collection of strings.

Only the first instance of the value will be changed if you’re replacing a value rather than a regular expression. Use the global (g) modifier to replace all instances of a given value.

jQuery Replace String, Text, or HTML Element

Using the jQuery replace() function you can replace the specific string from the sentence. So if you want to change or replace the string from the sentence or text then use the replace function.

First, we will target that element where we want to make changes then we run the replace function by passing the targeted element and string. It will only replace the string at the first occurrence from the sentence. It means when you run the replace() function it will search the replaceable text from the sentence and where it is found it will stop.

Note: You need to use the replaceAll() function to replace all the occurrences of a string. We will cover later in the examples below.

Example 1 – jQuery Replace String

Let’s see the example of the jquery replace() function to replace the string.

<!DOCTYPE html>
<html>
	<head>
		<title>jQuery Replace String</title>
		<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
	</head>

	<body>

		<h2>jQuery Replace String Example</h2>

		<p id="demo">Where you want to use jQuery replace() function?</p>

		<button>Replace</button>

		<p><strong>Note:</strong> It will replace the 'function' string with 'method'</p>

		<script>
			jQuery('button').click(function() {
			    var text = jQuery("#demo").text();
			    text = text.replace("function", "method");  
			    jQuery("#demo").text(text);
			});
