IE7 - invalid procedure call or argument when calling removeAttr('contenteditable');

[brian@…]

When calling .removeAttr('contenteditable') on a span I get a JS error in IE7 on line 2485 of jquery-1.6.4.js. The error says "Invalid procedure call or argument".

I tried to make a jsfiddle for this but jsfiddle appears to be broken in IE7.

Make a fiddle in another browser, where the error doesn't occur and we can run it in IE7

Sure here you go:  http://jsfiddle.net/f1sherman/5XVX3/3/

Unfortunately I couldn't test it because I get a JS error when I try to load the page in IE7.

Yep, that shouldn't be throwing an error.

In the meantime, set contenteditable to 'false' instead. Since contenteditable is an enumerated attribute, removing it and setting it to 'false' has the same effect.

$(elem).attr('contenteditable', 'false');

Internally, we set attributes to empty string before removal, but IE balks and throws an error because empty string is not a "valid value" for contenteditable (even though it actually is, ironically). Both removeAttribute and removeAttributeNode have no effect on contenteditable in IE6/7, so in order to kill the behavior of contenteditable, it HAS to be set to 'false'. We can provide an attrHook that does this in 1.7, but if removeAttr is used to remove contenteditable and then one tries to get contenteditable, he or she will get undefined in all browsers where contenteditable was actually removed and 'false' in IE6/7 (which is really unavoidable). Either way, I recommend using the other values "true", "false", or "inherit".

Add a hook for removing contenteditable in IE6/7 and remove the unnecessary jQuery.attrFix. Fixes #10429.
