Get content of a DIV using JavaScript

36

I have two DIV's called DIV1 and DIV2 and DIV1 consists of dynamic content and DIV2 is empty. I need content of DIV1 to be displayed in DIV2. How can I do it.

I coded in below manner which is not working. Anybody please correct it.

<script type="text/javascript">

   var MyDiv1 = Document.getElementById('DIV1');
   var MyDiv2 = Document.getElementById('Div2');
   MyDiv2.innerHTML = MyDiv2; 

</script>
<body>
<div id="DIV1">
 // Some content goes here.
</div>

<div id="DIV2">
</div>
</body>

(1) Your <script> tag should be placed before the closing </body> tag. Your JavaScript is trying to manipulate HTML elements that haven't been loaded into the DOM yet.
(2) Your assignment of HTML content looks jumbled.
(3) Be consistent with the case in your element ID, i.e. 'DIV2' vs 'Div2'
(4) User lower case for 'document' object (credit: ThatOtherPerson)

<body>
<div id="DIV1">
 // Some content goes here.
</div>

<div id="DIV2">
</div>
<script type="text/javascript">

   var MyDiv1 = document.getElementById('DIV1');
   var MyDiv2 = document.getElementById('DIV2');
   MyDiv2.innerHTML = MyDiv1.innerHTML;

</script>
</body>

Right now you're setting the innerHTML to an entire div element; you want to set it to just the innerHTML. Also, I think you want MyDiv2.innerHTML = MyDiv 1 .innerHTML. Also, I think the argument to document.getElementById is case sensitive. You were passing Div2 when you wanted DIV2

var MyDiv1 = Document.getElementById('DIV1');
var MyDiv2 = Document.getElementById('DIV2');
MyDiv2.innerHTML = MyDiv1.innerHTML; 

Also, this code will run before your DOM is ready. You can either put this script at the bottom of your body like paislee said, or put it in your body's onload function

<body onload="loadFunction()">

and then

function loadFunction(){
    var MyDiv1 = Document.getElementById('DIV1');
    var MyDiv2 = Document.getElementById('DIV2');
    MyDiv2.innerHTML = MyDiv1.innerHTML; 
}
