AJAX IE6 with quirks mode runtime error

Reported by: zardoz Owned by: flesler
Priority: major Milestone: 1.3
Component: ajax Version: 1.2.6
Keywords: Cc: zardoz
Blocked by: Blocking:

If you are in IE6 and do an ajax get to insert

some snippet with a script/style tag. The new tag

is inserted inside the <base> not the <head> causing

a runtime error when the ajax call tries to remove the <script> later.

Here's the HTML we had

--- blank line here ignores the DOCTYPE an puts IE in quirks mode ---

<!DOCTYPE html PUBLIC "-W3CDTD XHTML 1.0 TransitionalEN" ""><html

xmlns= ""

xml:lang= "en"

lang= "en"><head><base target="_top"/>

And here's the offending line of jquery.js

ajax: function( s ) {


if( head )

head.removeChild( script );


Seems like the change below is more robust and guaranteed to work for any node whatsoever.

if( head && script)

script.parentNode.removeChild( script );

There are a few other places in jquery with does this same kind of removal.
