You can use <code>setTimeout()</code> and <code>clearTimeout()</code> in conjunction with <a href="http://api.jquery.com/jQuery.data/" rel="noreferrer"><code>jQuery.data</code></a>:

<pre><code>$(window).resize(function() {
 clearTimeout($.data(this, 'resizeTimer'));
 $.data(this, 'resizeTimer', setTimeout(function() {
 //do something
 alert("Haven't resized in 200ms!");
 }, 200));
});
</code></pre>

Update

I wrote an extension to enhance jQuery's default <code>on</code> (&amp; <code>bind</code>)-event-handler. It attaches an event handler function for one or more events to the selected elements if the event was not triggered for a given interval. This is useful if you want to fire a callback only after a delay, like the resize event, or else.
<a href="https://github.com/yckart/jquery.unevent.js" rel="noreferrer">https://github.com/yckart/jquery.unevent.js</a>

<pre><code>;(function ($) {
 var methods = { on: $.fn.on, bind: $.fn.bind };
 $.each(methods, function(k){
 $.fn[k] = function () {
 var args = [].slice.call(arguments),
 delay = args.pop(),
 fn = args.pop(),
 timer;

 args.push(function () {
 var self = this,
 arg = arguments;
 clearTimeout(timer);
 timer = setTimeout(function(){
 fn.apply(self, [].slice.call(arg));
 }, delay);
 });

 return methods[k].apply(this, isNaN(delay) ? arguments : args);
 };
 });
}(jQuery));
</code></pre>

Use it like any other <code>on</code> or <code>bind</code>-event handler, except that you can pass an extra parameter as a last:

<pre><code>$(window).on('resize', function(e) {
 console.log(e.type + '-event was 200ms not triggered');
}, 200);
</code></pre>

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:

<pre><code>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) + " -&gt; " + 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
});
</code></pre>

This is my approach:

<pre><code>document.addEventListener('DOMContentLoaded', function(){
 var tos = {};
 var idi = 0;
 var fn = function(id)
 {
 var len = Object.keys(tos).length;

 if(len == 0)
 return;

 to = tos[id];
 delete tos[id];

 if(len-1 == 0)
 console.log('Resize finished trigger');
 };

 window.addEventListener('resize', function(){
 idi++;
 var id = 'id-'+idi;
 tos[id] = window.setTimeout(function(){fn(id)}, 500);
 });
});
</code></pre>

The resize-event-listener catches all incoming resize calls, creates a timeout-function for each and saves the timeout-identifier along with an iterating number prepended by <code>'id-'</code> (to be usable as array key) in the <code>tos</code>-array.

each time, the timout triggers, it calls the <code>fn</code>-function, that checks, if that was the last timeout in the <code>tos</code> array (the fn-function deletes every executed timout). if true (= <code>if(len-1 == 0)</code>), the resizing is finished.

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 event function:

<pre><code>$(window).resize(function() {
 ... // how to call only once the browser has FINISHED resizing?
});
</code></pre>

However, this function is called continuously if the user is manually resizing the browser window. Which means, it might call this function dozens of times in short interval of time.

How can I call the resize function only a single time (once the browser window has finished resizing)?

UPDATE

Also without having to use a global variable.
