IE "Invalid Argument" $('table').attr('non-existent')

[jdsharp]

IE 6 throws an "Invalid Argument" error when attempting to get an attribute from a table element. Functions as desired with a div (returns undefined). Fix attached. (Is broken in 1.1.3.1, 1.1.4, 1.2)

Some more research reveled that this only occurs when the attribute in question contains a ':'. Updated patch as follows:

Fixes a getAttribute 'Invalid Exception' error when getting an attribute with a ':' in it on a table element when the attribute does not exist ​http://www.andrewdupont.net/2007/01/10/code-hasattribute-for-ie/ if ( jQuery.browser.msie ) {

if ( /href|src/.test(name) && !jQuery.isXMLDoc(elem) )

return elem.getAttribute( name, 2 );

if ( name.indexOf(':') > -1 )

return ( elem.attributes[name] != undefined ? elem.getAttribute(name) : undefined );

} return elem.getAttribute( name );

Tried the above patch, does not fix the error in IE6, however this did fix a problem I was having in Safari on Windows XP. I was trying to use hover() and hoverIntent() on an unordered list, and neither worked - however this fix solved the problem

This bug is still present in 1.2.2 and the same patch still applies.

Tested this with the trunk version, and it works fine. This was probably fixed with the recent massive modifications to .attr().

I tested on IE6.

[jdsharp]

This issue still existed in 1.2.6, I've created a patch against trunk

Any progress on this one? It's been 8 months and I'm still able to reproduce this in jQuery 1.3.1.

See the discussion in dup #3278

[danheberden]

Still an issue - though IE9 fails on all three :/

What about ​http://jsfiddle.net/timmywil/YxRUP/2/? I don't have IE9 to test.

[Timmy Willison]

Actually, still a problem in IE6 in that test.

Updated version of the test case using jQuery git: ​http://jsfiddle.net/YxRUP/3/

[Timmy Willison]

Dan's, John's, and my test cases all pass in IE9 so I don't think this is a problem in IE9, but it is a problem for IE6/7. Any attribute with a colon on a table element throws an "Invalid Argument" exception. I've created another ​test case as well. Working on a possible fix.

[Timmy Willison]

Test for a colon in attribute names for IE6/7. Fixes #1591.
