JQuery 1.6.1 and Checkbox Attr

I am using JQuery 1.6.1 and found that

 $("#theChk').attr("checked", ""); 

OR

$("#theChk").prop("checked", false);

none of this are working . Can some one find reason based on this http://blog.jquery.it/2011/05/10/jquery-1-6-1-rc-1-released/ ?

Do I have to 开发者_高级运维change whole application for this change ??!!

You're having " on the left side of selector and ' on the right side of selector

and use .attr

$("#theChk").attr("checked", false); 

to uncheck it, to check it use

$("#theChk").attr("checked", true); 

$("#theChk").removeAttr("checked");

Try changing it to this:

 $('#theChk').attr('checked', false);

checked takes a boolean not a string. I'm not sure why your example that uses prop is not working. From what I can see that looks fine.

If you're setting a value, use .prop and a non-quoted boolean:

$('#theChk').prop('checked', true)

If youre checking if it's checked, leave out the boolean:

if ($('#theChk').prop('checked'))

So it depends on what you're trying to do.
