checkboxEl.attr('checked') returns stale value after checkboxEl.click()

[IgorMinar]

This worked fine in 1.6.2: ​http://jsfiddle.net/IgorMinar/69fpq/1/

but is broken in 1.6.3 and 1.6.4: ​http://jsfiddle.net/IgorMinar/69fpq/

An issue was introduced in the boolHook for non-IE browsers.

[IgorMinar]

Indeed the issue is in boolHook:

// Hook for boolean attributes
boolHook = {
    get: function( elem, name ) {
        // Align boolean attributes with corresponding properties
        // Fall back to attribute presence where some booleans are not supported
        var attrNode;
        return jQuery.prop( elem, name ) === true || ( attrNode = elem.getAttributeNode( name ) ) && attrNode.nodeValue !== false ?
            name.toLowerCase() :
            undefined;
    },

More specifically the check: attrNode.nodeValue !== false succeeds when it shouldn't because the value is an empty string and not false.

[IgorMinar]

While #10271 (marked as duplicate of this issue) is caused by an issue in boolHook it is a different issue present in the set method, while this one is in the get method.

@IgorMinar: There is fix for this for 1.7 here: ​https://github.com/jquery/jquery/commit/2931fa875f7520f87f79c6cff8b1a40d0b4d141a

If there is an issue with set, please provide a test case on ​http://jsfiddle.net to help us reproduce it.

I see the milestone is set to 1.7. Is this going to get backported to a 1.6.x release?

[timmywil]

No, but the recommended way to get/set booleans is to get/set the properties with the .prop() method. This fix will be available in 1.7, but the boolHook may be deprecated and eventually removed.

[timmywil]

Check for property support in the boolHook before falling back to attribute node. Fixes #10278.

CHECKBOXEL.ATTR('CHECKED')is still return "checked" for checked and "undefined" for unchecked checkbox

[anonymous]

I am having the same issue:

CHECKBOXEL.ATTR('CHECKED')is still return "checked" for checked and "undefined" for unchecked checkbox

any updates?

[timmywil]

That is the desired behavior, but I recommend using ​http://api.jquery.com/prop to check the checked value.
