Question

How can I get a checkbox’s value in jQuery?

Answer 1

To check whether it is checked or not, do:

if ($('#check_id').is(":checked"))
{
  // it is checked
}

To get the value of the Value attribute you can do something like this:

$("input[type='checkbox']").val();

Or if you have set a class or id for it, you can:

$('#check_id').val();
$('.check_class').val();

However this will return the same value whether it is checked or not, this can be confusing as it is different to the submitted form behaviour.
