Please Help! There has to be a quick .js fix for Spry dropdown to work for iPads...

Question

I know I can upgrade, download, purchase or any combination of these to get and use a new dropdown menu format that would work, but that is not what I want to work on learning today.  Our top coder/developer is out of town right now, and I am just trying to fix a menu bar that was done in CS4 with Spry 1.6.1, and I have to believe that someone out there knows the fix to get it to work on an ipad.  I can make the parent li not a link and it still does not work.  Here is my .JS code:

SpryMenuBar.js
This file handles the JavaScript for Spry Menu Bar.  You should have no need
to edit this file.  Some highlights of the MenuBar object is that timers are
used to keep submenus from showing up until the user has hovered over the parent
menu item for some time, as well as a timer for when they leave a submenu to keep
showing that submenu until the timer fires.

Answer 1

Try the following changes to the JS file
Lines 103 and 104 change the values
this.showDelay = 100; // was 250
this.hideDelay = 200; // was 600
Comment out line 286
Spry.Widget.MenuBar.prototype.bubbledTextEvent = function()
//    return Spry.is.safari && (event.target == event.relatedTarget.parentNode || (event.eventPhase == 3 && event.target.parentNode == event.relatedTarget));
Comment out line 366 and add new lines 366 and 367
var self = this;
this.addEventListener(listitem, 'click', function(e){self.Click(listitem, e);}, false);
this.addEventListener(listitem, 'click', function(e){self.mouseOver(listitem, e);}, false);
//   this.addEventListener(listitem, 'mouseover', function(e){self.mouseOver(listitem, e);}, false);
this.addEventListener(listitem, 'mouseout', function(e){if (self.enableKeyboardNavigation) self.clearSelection(); self.mouseOut(listitem, e);}, false);
I have not tested the above changes ontouch screens; they do seem to work Ok on desktops.
NOTE: Line numbers could be different because of the difference in our versions.
