java script functionality only in mobile device

Question

I want java script functionality only in mobile device 767px. This is my code

$('#my-btnn').click(function () {
    $('#mobile-login').hide();
    $('#user-settings').slideToggle('fast');
});

Answer 1

You can simply check window width in order to determine if function should work or not:

$('#my-btnn').click(function () {
    if ($(window).width() < 767) {
        $('#mobile-login').hide();
        $('#user-settings').slideToggle('fast');
    }
});
