touch events firing twice

Question

I am having problems on mobile devices/tablets with the events firing twice. When I click the following function, the menu that is supposed to drop down will drop down then

Answer 1

In most cases the following code will be ok:

$(document).on("touchend click", ".lines-button", function(e){
    if(e.type == 'touchend'){
        $(this).off('click');
    }
});

If touchend works, you may get rid of click.
