• The easiest solution is probably to use the JQuery library.

  http://docs.jquery.com/Ajax/jQuery.get

  $.get("mypage.html", function(data){
    alert("Data Loaded: " + data);
  });
  

• I think that this should do the trick. It's untested but give it a try.

  document.documentElement.innerHTML
  

  Another approach could be to query the URL through XmlHttpRequest and read the response.responseText
