Introduction
This post shows how to clone elements of a web page using jQuery; for this we will use the .clone() method.
Sometimes we want to copy (clone) elements of a web page; for example, a navigate menu can be placed on the header and on the footer too and there may be many situations that occur where we need to make a clone. Why write something twice if we have the opportunity to use jQuery.
So, let's create a demonstration page for this article.
<body>
<h2>History of Visual Studioh2>
<div class="mainBody">
Visual Studio's history probably begins in <strong class="year">1975strong> with Bill and Paul's decision to create Altair BASIC. Maybe you could start before that but I think that's as far back as you could go and still say it's about Visual Studio at all รข€“ it's at that time that Microsoft decided it was going to have software development products and not, say, toaster automation.

Let's assume; we want to copy the 'mainBody'
and place it after the first . To do this we will use the following jQuery:
$('div.mainBody').clone().insertAfter('p:eq(0)');
In the above jQuery, making the clone of the
that has the class "mainBody" and inserting this new clone after the first , in DOM 0 refers the very first
, 1 refers the second
and so on.
, 1 refers the second
and so on.
Output in the browser:
Take one more assumption; what if we want to apply a different style to the cloned copy??
Now, to do that we need to create a style class.
<style type="text/css">
.cloneStyle {
background: #ead3d3;
font: italic 1.4em "Times New Roman", Times, serif;
}
style>
So, we have a style now; let's add it to the cloned copy.
$('div.mainBody').clone().insertAfter('p:eq(0)').addClass('cloneStyle');
Nothing new here; we just added one more attribute .addClass('cloneStyle') to the existing jQuery above.
Now look at the output in the browser:
So, that's all about making a clone in a web page. You can dive deeper into this topic to achieve more functionality.
