#6534 closed bug (invalid)

"doc.createDocumentFragment is not a function" error in 1.4+ when appending a function like so

Reported by: seasoup Owned by:

This throws an error in 1.4 and 1.4.2 but not in 1.3.2. Didn't test 1.4.1

Test Case: <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script> <script>

var Dialog = function() {



Dialog.prototype = {

'loadingDialog': function () { return 'foo' }


var car = new Dialog();


The above code results in doc being a Window object below

fragment = doc.createDocumentFragment(); line 4373

which breaks it. Putting the following in front of it seems to fix it, but I don't know all the repercussions.

if (doc.constructor === Window) {

doc = document;



var car = new Dialog();

in a $(function () {} fixes it too.

  • Resolution set to invalid
  • Status changed from new to closed

The new Dialog() constructor happens outside a .ready() handler. jQuery doesn't guarantee it's ready until then. Perhaps it worked in 1.3 but it wasn't guaranteed.
