[jQuery] Re: Turning a checkbox on and off

[Marshall Salinger]

That is a strange find. I wouldn't have thought to test a different string outside of the html spec for setting it to checked. I guess any value as a string will return true. You can use $('your_selector').attr('checked',''); or attr('checked',false); as you stated, to uncheck the box.

And how do you determine if a checkbox has been checked or unchecked? I tried attr and css and none of them worked. Thanks Mitch
