$('[selected]') Has Attribute Selector failing in IE8

[miketaylr]

Summary: $('[selected]') always fails in IE8 (but not ie6, or ie7)

It appears that IE8 has a bug in its querySelectorAll implementation, so I think Sizzle is just inheriting the problem here.

$('[selected=selected]) works, whereas $('[selected]') never does.

Here's a link to the qunit tests on "boolean" Has Attribute selectors: ​http://miketaylr.com/test/qunit/has_attribute_selector.html

Also, here's a simple test page on the IE8 QSA broken-ness: ​http://miketaylr.com/test/ie8qsa.html

I think we're just recommending that people use :selected instead of [selected] in their code. Not only is it easier to use but it's also consistent across platforms.

Didn't mean to close this, it's still something we want to tackle.

Im using a content mgmt solution that spits in an extra title tag. To figure out what content I am including I have <title context="howc"></title>.

When I try var context = $("title[context]]").attr("context"); context is undefined.

Maybe because my <Title tag is in the wrong place (inside body) maybe because context is not a valid attribute of <Title?

I can clean this up and get something working, but I thought I'd add this to the bug. Thanks.

I think IE stripped the tag out or something.

This doesn't work either:

var context; $("title").each(function(){

if($(this).attr("context"))

context=$(this).attr("context");

}) alert(context); undefined ie7 works in firefox

This is getting moved to 1.6 for when the $.attr happens.
