JavaScript is widely used in web page development and its libraries like JQuery are very handy. In old technologies, it was nearly impossible to change or replace an HTML element using server-side scripting languages, we were only able to change the content inside the element through the backend languages. But thanks to JavaScript, it made life easier and allowed us to dynamically change the element of the webpage. It provides
various methods to achieve this functionality but the one we are going to look at in this post is the JQuery’s replacewith[] method. Let’s take a deep look at this method. In jQuery, the replaceWith[] function is used to replace chosen components with new ones and it returns the components that have been replaced. The replaceWith[] method syntax is mentioned below. $[element].replaceWith[newContent,
[idx]=>{}] Here’s the explanation of the arguments of replacewith[] method To better understand how to utilize the replaceWith[] function, consider the following examples. Suppose, we have a The HTML part would be like this: And at the click of a button, we want to replace the Now, to completely convert the $[document].ready[function[]{ $["#btn"].click[function[] {
$["#element1"].replaceWith[" Element Replaced :] }]; }]; In the above example, we are simply first fetching the HTML element by using the IDs of the button and div tag and then replacing the Output You can witness that the element was successfully replaced. JavaScript’s replacewith[] method is used to replace one HTML element with some other element according to the requirement. This replacewith[] method takes two arguments, the first argument is the content that you want to be replaced with while the second argument is used to return the index position of
the content that you want to replace with. In this article, we have discussed the examples of replacing the old content with the new one using JQuery. A

style and structure. Please refer to DOM [Document Object Model] to know the details. We can implement this by using DOM’s createElement[], createTextNode[], appendChild[], replaceChild[] methods and childNodes property. Let us discuss these methods and property to replace one HTML element to another. In this example, the element is “h2” tag, so write Syntax: The following shows the working code on how to use
these methods and property discussed above. Output: childNodes[Position]: This property returns a collection of child nodes as a NodeList object. The nodes are sorted as they appear in source code and can be accessed by index number starting from 0. replaceChild[]: It replace a child node with new node. Example: The following code shows how to replace element with another one. Output:Arguments Explanation

// Creating "h2" element
var H = document.createElement["h2"];
// Retaining id
H.setAttribute["id", "red"];
// Creating Text node
var txt = document.createTextNode["Hello Geeks!!"];
// Accessing the Element we want to replace
var repNode = document.getElementById["p1"];

To change the element tag name in JavaScript, simply need to make a new element and move over all the elements so you keep title handlers and such, and then replace the original thing.
The replace[] method searches a string for a value or a regular expression. The replace[] method returns a new string with the value[s] replaced. The replace[] method does not change the original string.
The HTML tags can be removed from a given string by using replaceAll[] method of String class. We can remove the HTML tags from a given string by using a regular expression. After removing the HTML tags from a string, it will return a string as normal text.
