Get checkbox value in jQuery

Question

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

Answer 1

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.

To check whether it is checked or not, do:

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