I had a problem a while back where i needed to put the contents of a div into another div, the reason for this was because i couldn’t access the source code of the page to modify the div contents, as it was built using a CMS, so the only option was to use .append() in jQuery to do the job.

The code.

$(document).ready(function(){
var contentDiv = $('#contentDiv').html();
$('#Container').append(contentDiv);
$('#contentDiv').remove();
 });

You need to include the jQuery framework to get started, with the above configuration we’re taking the div #contentDiv and placing it into #Container, then we remove the original #contentDiv from the page.
