/*** hoverIntent is similar to jQuery's built-in "hover" function except that* instead of firing the onMouseOver event immediately, hoverIntent checks* to see if the user's mouse has slowed down (beneath the sensitivity* threshold) before firing the onMouseOver event.* * hoverIntent r6 // 2011.02.26 // jQuery 1.5.1+* <http://cherne.net/brian/resources/jquery.hoverIntent.html>* * hoverIntent is currently available for use in all personal or commercial * projects under both MIT and GPL licenses. This means that you can choose * the license that best suits your project, and use it accordingly.* * // basic usage (just like .hover) receives onMouseOver and onMouseOut functions* $("ul li").hoverIntent( showNav , hideNav );* * // advanced usage receives configuration object only* $("ul li").hoverIntent({* sensitivity: 7, // number = sensitivity threshold (must be 1 or higher)* interval: 100, // number = milliseconds of polling interval* over: showNav, // function = onMouseOver callback (required)* timeout: 0, // number = milliseconds delay before onMouseOut function call* out: hideNav // function = onMouseOut callback (required)* });* * @param f onMouseOver function || An object with configuration options* @param g onMouseOut function || Nothing (use configuration options object)* @author Brian Cherne brian(at)cherne(dot)net*/(function($) { $.fn.hoverIntent = function(f,g) { // default configuration options var cfg = { sensitivity: 7, interval: 100, timeout: 0 }; // override configuration options with user supplied object cfg = $.extend(cfg, g ? { over: f, out: g } : f ); // instantiate variables // cX, cY = current X and Y position of mouse, updated by mousemove event // pX, pY = previous X and Y position of mouse, set by mouseover and polling interval var cX, cY, pX, pY; // A private function for getting mouse position var track = function(ev) { cX = ev.pageX; cY = ev.pageY; }; // A private function for comparing current and previous mouse position var compare = function(ev,ob) { ob.hoverIntent_t = clearTimeout(ob.hoverIntent_t); // compare mouse positions to see if they've crossed the threshold if ( ( Math.abs(pX-cX) + Math.abs(pY-cY) ) < cfg.sensitivity ) { $(ob).unbind("mousemove",track); // set hoverIntent state to true (so mouseOut can be called) ob.hoverIntent_s = 1; return cfg.over.apply(ob,[ev]); } else { // set previous coordinates for next time pX = cX; pY = cY; // use self-calling timeout, guarantees intervals are spaced out properly (avoids JavaScript timer bugs) ob.hoverIntent_t = setTimeout( function(){compare(ev, ob);} , cfg.interval ); } }; // A private function for delaying the mouseOut function var delay = function(ev,ob) { ob.hoverIntent_t = clearTimeout(ob.hoverIntent_t); ob.hoverIntent_s = 0; return cfg.out.apply(ob,[ev]); }; // A private function for handling mouse 'hovering' var handleHover = function(e) { // copy objects to be passed into t (required for event object to be passed in IE) var ev = jQuery.extend({},e); var ob = this; // cancel hoverIntent timer if it exists if (ob.hoverIntent_t) { ob.hoverIntent_t = clearTimeout(ob.hoverIntent_t); } // if e.type == "mouseenter" if (e.type == "mouseenter") { // set "previous" X and Y position based on initial entry point pX = ev.pageX; pY = ev.pageY; // update "current" X and Y position based on mousemove $(ob).bind("mousemove",track); // start polling interval (self-calling timeout) to compare mouse coordinates over time if (ob.hoverIntent_s != 1) { ob.hoverIntent_t = setTimeout( function(){compare(ev,ob);} , cfg.interval );} // else e.type == "mouseleave" } else { // unbind expensive mousemove event $(ob).unbind("mousemove",track); // if hoverIntent state is true, then call the mouseOut function after the specified delay if (ob.hoverIntent_s == 1) { ob.hoverIntent_t = setTimeout( function(){delay(ev,ob);} , cfg.timeout );} } }; // bind the function to the two event listeners return this.bind('mouseenter',handleHover).bind('mouseleave',handleHover); };})(jQuery);
