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

This is what I use for delaying repeated actions, it can be called in multiple places in your code:

function debounce(func, wait, immediate) {
    var timeout;
    return function() {
        var context = this, args = arguments;
        var later = function() {
            timeout = null;
            if (!immediate) func.apply(context, args);
        };
        var callNow = immediate && !timeout;
        clearTimeout(timeout);
        timeout = setTimeout(later, wait);
        if (callNow) func.apply(context, args);
    };
};

Usage:

$(window).resize(function () { 
   debounce(function() {
          //...
    }, 500);
});
