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

[jdsharp]

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

Still an issue - IE9 can't get at all on a table element :/

however, document.getElementById( 'table1' ).getAttribute( 'ric:attrib' ) works just fine

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

[timmywil]

Actually, still a problem in IE6 in that test.

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

[timmywil]

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.

[timmywil]

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