javascript - setTimeout not working on safari mobile

Question

I have a function that shows a menu when clicking on it, and I want it to disappear after 5 seconds. This is my javascript - it works properly on desktop browser but it doesn't disappear on the mobile ones.

$(function() {
    $('#prod_btn').click(function() {
        $(this).addClass('selected').next('ul').css('display', 'block');
        setTimeout(hideMenu, 5000);
    });
});

function hideMenu() {
    $('#prod_btn').removeClass('selected').next('ul').css('display', 'none');
}

Where is the problem?

Thanks

I've just had the same problem. My code is running great in any browser on my Mac, but on iOs devices it doesn't work.

I use ".bind(this)" on my timeout function and that is what is causing the problem for me. When I extend the function object with ".bind" in my script it works like a charm.

My code is something like this:

searchTimeout = setTimeout(function() {
...
}.bind(this),250);

For this to work on iOs devices I (like mentioned above) just added this:

Function.prototype.bind = function(parent) {
    var f = this;
    var args = [];

    for (var a = 1; a < arguments.length; a++) {
        args[args.length] = arguments[a];
    }

    var temp = function() {
        return f.apply(parent, args);
    }

    return(temp);
}

I don't see any .bind on your setTimeout, but for others with the same problem this may be the issue. That's why I'm posting :-)
