Question

The following code works fine in Chrome but does nothing in FF and IE. How can I debug this? The way that Im developing locally means I cant make my code publicly accessible.

$(document).ready(function () {
       // alert('dfd');
        $('#mobileMenuLink a').click(function () {
            event.preventDefault();
            // alert('dfd');
            $('#menu').toggleClass('mobileMenuOpen');
        });
    });

Answer 1

What is event? Maybe you just missed a parameter declaration:

$('#mobileMenuLink a').click(function (event) {
    event.preventDefault();
    $('#menu').toggleClass('mobileMenuOpen');
});
