Selectors don't work with jQuery context

[bartt]

Many (if not all) selectors don't work with jQuery context. See the demo on http://docs.jquery.com/Ajax/load#urldatacallback for example.

Other forms such as jQuery("#me", jQuery("<div id='notme'>notme</div> <div id='me'>ME!</div>") also fail. Same for jQuery("<div id='notme'>notme</div> <div id='me'>ME!</div>").find("#me").

It seems to be caused by the lack of nodeType in jQuery objects. Selectors that take context arguments check the nodeType to make sure they received an Element or Document type.
