I want to get the ID of a div using JavaScript that runs inside that div. I want to appendChild() html to that div.

eg:

<div id="randomnumber">
<script type="text/javascript"> 
var htmlcontent = "abcdf";
//need the id of div holder
var thisDIVid= ?????;
// appendChild to this div
?????.appendChild(htmlcontent);
</script>
</div>

If you know where in the structure your div is placed you can access it like this:

var mainDiv = document.getElementById('mainDiv');
yourDiv = mainDiv.getElementsByTagName('div')[number];

number is the place in the structure

-2

document.getElementyById("yourDivId"); will find any div with an unique ID. 

var div = document.getElementyById("yourDivId");
div.appendChild("yourContent");

  • You can find divs by className and then If you now where in your HTML structure it is paste the content there. – Jacob Feb 26 '13 at 11:36
