Good day all.
I'm having some problems with hoverintent.js
a jquery plugin that handle the mouseOver events in a different way than normal.
Due to some complications, I can't modifiy anything but the js of this plugin, but I need to make it compliant with touch events and not only with mouseOver and mouseLeave.
after some debugs, I have managed to recognize this part of the code to be the one to modify:
var handleHover = function(e) {
// next three lines copied from jQuery.hover, ignore children onMouseOver/onMouseOut
var p = (e.type == "mouseover" ? e.fromElement : e.toElement) || e.relatedTarget;
while ( p && p != this ) { try { p = p.parentNode; } catch(e) { p = this; } }
if ( p == this ) { return false; }
// 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); }
// else e.type == "onmouseover"
if (e.type == "mouseover") {
// 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 == "onmouseout"
} 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.mouseover(handleHover).mouseout(handleHover);
what I've done so far is to make the function working different with mobiles:
var handleHover = function(e) {
isMobile = /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent);
if(isMobile){
console.log("Ismobile");
}else{
... Same code as before here ...
}
// bind the function to the two event listeners
return this.mouseover(handleHover).mouseout(handleHover);
and now i'm struck. I would like it to "change" its behavior to handle the touch, and not the mouse over event, so on mobiles I will need to touch the element, instead to hovering on it. May someone give me an help? Am I on the right way? Is it the right way to think of it?
unluckily I have only the possibility to change this file and some few more.
Recently i bumped into several problems with changing hoverIntent.js, and ended up in writing my own plugin: hoverDelay.js (much simpler, and less code). see if you can use it, and modify it to your own needs (and maybe contribute the mobile code to it :-)
