How to wait for the 'end' of 'resize' event and only then perform an action?

Question

So I currently use something like:

$(window).resize(function(){resizedw();});

But this gets called many times while resizing process goes o

Here is VERY simple script to trigger both a 'resizestart' and 'resizeend' event on the window object.

There is no need to muck around with dates and times.

The d variable represents the number of milliseconds between resize events before triggering the resize end event, you can play with this to change how sensitive the end event is.

To listen to these events all you need to do is:

resizestart: $(window).on('resizestart', function(event){console.log('Resize Start!');});

resizeend: $(window).on('resizeend', function(event){console.log('Resize End!');});

(function ($) {
    var d = 250, t = null, e = null, h, r = false;

    h = function () {
        r = false;
        $(window).trigger('resizeend', e);
    };

    $(window).on('resize', function (event) {
        e = event || e;
        clearTimeout(t);

        if (!r) {
            $(window).trigger('resizestart', e);
            r = true;
        }

        t = setTimeout(h, d);
    });
}(jQuery));
