How to control the checkbox when value is set?

Question

Django

$(".update").click(function() {
            if ($("#top").val('notop')) {
                $('input[name="top"]').attr('checked', false);
            } else {
                $('input[name="top"]').attr('checked', true);
            }
        });

When the button is pressed, if the input has the value "notop", check should be false.
Why is my code not working?

Answer 1

just pull data from your system in the appropriate view in any convenient (whatever) way.

Answer 2

$('.update').click(function() {
  $('input[name="top"]').prop('checked', $('#top').val() !== 'notop');
});
