Learn how to check a checkbox using jQuery

By admin|jQuery

Think you need to check a checkbox using jQuery.

If jQuery 1.6+

Use the new .prop() function:

To set

$('.yourCheckbox').prop('checked', true);
$('.yourCheckbox').prop('checked', false);

To unset

$('.yourCheckbox').prop('checked', false);

if jQuery 1.5 and below

The .prop() function is not available on jQuery 1.5 and below, so you need to use .attr().

To set

$('.yourCheckbox').attr('checked','checked');

To unset

$('.yourCheckbox').attr('checked','');

or

$('.yourCheckbox').removeAttr('checked');
