How to uncheck checkbox using jQuery?

i try this and it working :D $("#id").prop('checked', true); i think it same as Mariusz Walczyk said :D

Try: $('#checkbox_id').attr('checked', false);

I usually use this: $('#id').removeAttr('checked');

Use prop() not attr() for this as attr() will not work in newer versions of jquery. Do jquery uncheck checkbox - 

$('#myCheckbox').prop('checked', false);

 

 

To uncheck a check box, use $("#id").attr('checked',false); or simply remove the attribute like $("#id").removeAttr('checked');

I'd have to second people who suggested you use $('#id').prop('checked', false) vs using attr() Prior to jQuery 1.6, jquery did not make a distinction between what's a property and what is an attribute of the element, and everything was handled via attr(), which made it a beast.
As of 1.6, they made the decision to handle properties via prop, which is meant to be more cross-browser.
For detailed explanation see this http://blog.jquery.com/2011/05/10/jquery-1-6-1-rc-1-released/

try this, it's fast way to swap the current value, from check to unchecked and vice versa: Check Me

this will change the value:

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

this will get you the value:

$("#theChk").prop("checked") or $("#theChk").attr("checked")

I think answer to your solution is here: just copy paste to your editor,n locate the jquery pakage.
n just try to check uncheck with a single button...cheers!!!!! jQuery check / uncheck a check box example jQuery check / uncheck a check box example Check Me

<inputtype="checkbox"id="myCheckbox"checked="checked"/><!-- Checked --><inputtype="checkbox"id="myCheckbox"/><!-- Unchecked --> $('#myCheckbox').attr('checked',true);// Checks it $('#myCheckbox').attr('checked',false);// Unchecks it

However, you cannot trust the .attr() method to get the value of the checkbox (if you need to). You will have to rely in the .prop() method.

So, for jQuery 1.6+

Use the new .prop() function as:

$('#myCheckbox').prop('checked', true); // Checks it $('#myCheckbox').prop('checked', false); // Unchecks it

<inputtype="checkbox"id="myCheckbox"checked="checked"/><!-- Checked --><inputtype="checkbox"id="myCheckbox"/><!-- Unchecked -->$('#myCheckbox').prop('checked',true);// Checks it $('#myCheckbox').prop('checked',false);// Unchecks it
