HTML/Javascript change div content

Assuming you're not using jQuery or some other library that makes this sort of thing easier for you, you can just use the element's innerHTML property.

document.getElementById("content").innerHTML = "whatever";

$('#content').html('whatever');

Get the id of the div whose content you want to change then assign the text as below:

  var myDiv = document.getElementById("divId");
  myDiv.innerHTML = "Content To Show";
