When jQuery is included in a page that is produced as the result of an XSLT transformation using an xml-stylesheet processing instruction, it may throw several errors related to missing namespaces and varying HTML DOM support depending upon the browser. This does not affect "vanilla" XHTML pages.

Affects:

Firefox 3.0.6 when transforming to XHTML

Note that under Firefox the provided test case will cause JavaScript to run twice, but only the second pass is relevant to this ticket (see https://bugzilla.mozilla.org/show_bug.cgi?id=380828)

https://bugzilla.mozilla.org/show_bug.cgi?id=230214 may explain the lack of document.body support in Firefox when transforming to XHTML

Safari 3.2.1 when transforming to XHTML

Chrome 1.0.154.48 when transforming to XHTML

Opera 9.63 when transforming to XHTML or HTML

Unaffected:

Internet Explorer 6, 7, 8 (XHTML output test not applicable)

Within the context of support.js, the following changes are one possible way to avoid any errors upon file load. There may also be more errors present when making jQuery method calls:

Fixes for Firefox and Webkit browsers:

replace calls to document.createElement("div") with document.createElementNS(document.documentElement.namespaceURI, "div")

Fixes for Firefox and Opera:

replace document.body with document.documentElement.getElementsByTagName("body")[0]
