Selectors with new HTML(5) input types don’t work in <= IE7

[mathias]

HTML:

<input type="search">

jQuery:

$('input[type="search"]').length; // should be 1, but is 0 in <= IE7
$('input[type="text"]').length; // should be 0, but is 1 in <= IE7
$('input').attr('type'); // should be "search", but is "text" in <= IE7
document.getElementsByTagName('input')[0].getAttribute('type'); // "search" (works everywhere)

It seems jQuery is using elem.type internally instead of elem.getAttribute('type'). In this case, there’s an important difference.

I’ve created a jsFiddle to illustrate the bug:  http://jsfiddle.net/mathias/XzGcW/ Note that it uses alert() so it can be debugged in a clean IE without any plugins installed.

P.S. This does not fix the bug, but I think that in src/selector.js, around line 613, this should be rewritten to elem.getAttribute('type') to prevent similar bugs with :text:

text: function( elem ) {
	return "text" === elem.type;
}

In src/attributes.js, near the end of attr (around line 346):

return elem[ name ];

…should probably be:

return elem.getAttribute(name);

This fixes the .attr() issue, but not the selector bug.

Edit: Of course, this change causes errors with className etc, see comment 3 by rwaldron.

One fix is to add a special case for the 'type' ATTR check that will force .getAttribute:

Sizzle.selectors.attrHandle['type'] = function ( elem ) { 
    return elem.getAttribute( 'type' ); 
} 

( change Sizzle to jQuery.find and you can monkey patch this bug on your own page: seen on  http://jsfiddle.net/gnarf/XzGcW/2/ )

Also, I'm not really sure why the default behavior in the attr function around ~790 of sizzle.js prefers to use elem[ name ] over elem.getAttribute( name ) but switching this to prefer elem.getAttribute may fix the need to have attrHandle at all since both the current one (href) and the proposed one for type just return .getAttribute()

I just applied this change and failed the following...

attributes: attr(String) (5, 14, 19)

2. Check for defaultValue attribute

10. Check for class attribute

17. Check for selectedIndex attribute

18. Died on test #18: Cannot call method 'toUpperCase' of null

attributes: attr(String, Object) (1, 29, 30)

3. Remove name attribute

attributes: addClass(String) (3, 2, 5)

3. Make sure there's no extra whitespace.

4. Make sure there's no extra whitespace.*

5. Make sure there isn't too much trimming.

attributes: addClass(Function) (3, 2, 5)

3. Make sure there's no extra whitespace.

4. Make sure there's no extra whitespace. *

5. Make sure there isn't too much trimming.

• yes, both named this

I can confirm that gnarf’s patch successfully fixes the problem, while passing all unit tests in all supported browsers, including IE7 and IE6.
