Simple jQuery ajax example not finding elements in returned HTML

Question

I\'m trying to learn jQuery\'s ajax functions. I\'ve got it working, but jQuery doesn\'t find elements in the returned HTML DOM. In the same folder as jquery, run this page:

Answer 1

I found that if ajaxtest-load.html does not have or tags but just a few html elements, it does work.

Edit:

If the input has to be a full HTML page, maybe you can first strip of the tags you don't want with string operations.. anyone?

Edit 2:

Vaguely remembered Javascript/DOM allowed for "temporary documents" which you could operate on and use the results from, then a bit of googling yielded a parseHTML function (http://www.daniweb.com/forums/post874892-2.html) which I've adapted to return the right bit:

$(document).ready(function(){
  $('input').click(function(){
    $.ajax({
      type : "POST",
      url : 'ajaxtest-load.html',
      dataType : "html",
      success: function(data) {
        alert( data ); // shows whole dom
        var gotcha = parseHTML(data, 'wrapper');
        if (gotcha) {
          alert($(gotcha).html());
        }else{
          alert('ID not found.');
        }
      },
      error : function() {
        alert("Sorry, The requested property could not be found.");
      }
    });
  });
});

function parseHTML(html, idStr) {
  var root = document.createElement("div");
  root.innerHTML = html;
  // Get all child nodes of root div
  var allChilds = root.childNodes;
  for (var i = 0; i < allChilds.length; i++) {
    if (allChilds[i].id && allChilds[i].id == idStr) {
      return allChilds[i];
    }
  }
  return false;
}

Does that work?
