JQuery: How to call RESIZE event only once it's FINISHED resizing?

Question

How do I call a function once the browser windows has FINISHED resizing?

I\'m trying to do it like so, but am having problems. I\'m using the JQuery Resize

Just to add to the above, it is common to get unwanted resize events because of scroll bars popping in and out, here is some code to avoid that:

function registerResize(f) {
    $(window).resize(function() {
        clearTimeout(this.resizeTimeout);
        this.resizeTimeout = setTimeout(function() {
            var oldOverflow = document.body.style.overflow;
            document.body.style.overflow = "hidden";
            var currHeight = $(window).height(),
                currWidth = $(window).width();
            document.body.style.overflow = oldOverflow;

            var prevUndefined = (typeof this.prevHeight === 'undefined' || typeof this.prevWidth === 'undefined');
            if (prevUndefined || this.prevHeight !== currHeight || this.prevWidth !== currWidth) {
                //console.log('Window size ' + (prevUndefined ? '' : this.prevHeight + "," + this.prevWidth) + " -> " + currHeight + "," + currWidth);
                this.prevHeight = currHeight;
                this.prevWidth = currWidth;

                f(currHeight, currWidth);
            }
        }, 200);
    });
    $(window).resize(); // initialize
}

registerResize(function(height, width) {
    // this will be called only once per resize regardless of scrollbars changes
});
