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.

jQuery(selector, context) is equivalent to jQuery(context).find(selector). The find method searches for matches BELOW the selected nodes. It is not the same as the filter method.

So, if you write your example this way:

jQuery("#me", jQuery("<div><div id='notme'>notme</div><div id='me'>ME!</div></div> "))

it works fine.
