Overriding check box in JavaScript with jQuery

Question

Help with unit testing checkbox behavior. I have this page:

Answer 1

How about using change instead of click?

$('#makeHidden').change(function() {
            var isChecked = $(this).is(':checked');

            if (isChecked) {
                $('#displayer').hide();
            }
            else {
                $('#displayer').show();
            }
            return false;
        });

The return false; won't be in the way since the event is fired as a result of the change having occurred.

Answer 2

Here is a work around.

Now my code is like this:

        if ($.browser.msie) {
            $('#makeHidden').change(function () {
                this.blur();
                this.focus();
                onCheckboxClicked();
            });
        }
        else {
            $('#makeHidden').change(function() {
                return onCheckboxClicked();
            });
        }

All my tests including manual toy and manual production are good.

Anybody have something better than this hack?

Try this:

$(function() {
    $('<div><input type="checkbox" name="makeHidden" id="makeHidden" checked="checked" />Make Hidden</div>').appendTo('body');
    $('<div id="displayer" style="display:none;">Was Hidden</div>').appendTo('body');

    $('#makeHidden').click(function() { return onCheckboxClicked(this) } );
});

function onCheckboxClicked(el) {
    var isChecked = $(el).is(':checked');

    if (isChecked) {
        $('#displayer').hide();
    }
    else {
        $('#displayer').show();
    }
    return false;
}
