Subject: Make the new attr/prop changes pass the test suite (in Webkit).  There are still... 
X-Git-Tag: 1.6b1~27^2~42
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=de79e8c7e0d1d2243447d59c70a9058eabf56bc3;p=jquery.git

Make the new attr/prop changes pass the test suite (in Webkit).  There are still errors in IE.

+ Added hooks for selected, checked, readonly, disabled to removeAttr if set to falsey

+ Removed all attrs from attrFix, these aren't needed for setAttribute

+ If prop is used for class, do we want a propFix for class?

  - We could just assume the user should know to use className with prop.  I've done the latter for now.

+ Created tests for $.fn.prop and $.fn.removeProp

  - Actually all I did was change broken attr tests to prop where it made sense.
