jQuery Checkbox Selector With Multi Attributes

I've got a jQuery selector thats not working desipte my best efforts to fix it. Any advic开发者_如何学运维e?

            $(':checkbox:(not(:checked))[name=this.name][value="Done"]').attr({
                checked: 'checked',
                disabled: 'disabled'
            });

It should check and disable a checkbox if it's not already checked, has a name attribute = this.name and a value of Done.

I've been fiddling around with it http://jsfiddle.net/PottyMonster/s8RMJ/ I dunno if that'll work though.

This should do it:

$('input[name=' + this.name + '][value=Done][type=checkbox]:not(:checked)').attr({
    checked: 'checked',
    disabled: 'disabled'
});

You need to concatenate the value of this.name into the selector.

I also added input to the selector to make it faster.

Also, you had an extra () around the :not() so it looked like :(not()) which isn't valid.

EDIT:

Just wanted to note that I had replaced the :checkbox selector with [type=checkbox] in order to make your selector valid for querySelectorAll.

Now it will get a big performance boost in browsers that support qsa.

change [name=this.name] to [name="'+this.name+'"]
and :checkbox to [type="checkbox"]
