How do I check a checkbox with JQuery or Javascript?

I'm trying to make a checkbox checked (or not) with jQuery.

My example HTML:

<input type="checkbox" id="test" name="test" />

Attempt at clearing a checkbox(doesn't work)

$('#test').val('off');

and at checking:

$('#test').val('on');

How do I control checkboxes with jQuery?

Answer 1

$('#test').prop('checked', true);

Note only in jQuery 1.6+

Answer 2

$('#checkbox').prop('checked', true);

When you want it unchecked:

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

Answer 3

$('#test').attr('checked','checked');

$('#test').removeAttr('checked');

Answer 4

I think you should use prop(), if you are using jQuery 1.6 onwards.

To check it you should do:

$('#test').prop('checked', true);

to uncheck it:

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

Answer 5

from jQuery v1.6 use prop

to check that is checkd or not

$('input:radio').prop('checked') // will return true or false

and to make it checkd use

$("input").prop("checked", true);

Answer 6

You don't need to control your checkBoxes with jQuery. You can do it with some simple JavaScript.

This JS snippet should work fine:

document.TheFormHere.test.Value = true;
