Smart window resize and smart delay callback functions.

/**
* Delay function to trigger callback function after given milliseconds
*/
delayfn = (function() {
var timer = 0;
return function(callback, ms) {
clearTimeout(timer);
timer = setTimeout(callback, ms);
};
})();

/**
* This function is used to detect browser resize and close the dropdown/overlays if opened..
*/
(function($, sr) {
var debounce = function(func, threshold,execAsap) {
var timeout;
return function debounced() {
var obj = this, args = arguments;
function delayed() {
if (!execAsap)
func.apply(obj, args);
timeout = null;
};
if (timeout)
clearTimeout(timeout);
else if (execAsap)
func.apply(obj, args);

timeout = setTimeout(delayed,threshold || 100);
};
};

jQuery.fn[sr] = function(fn) {
return fn ? this.bind(‘resize’,
debounce(fn)) : this.trigger(sr);
};
})(jQuery, ‘smartresize’);
