This is a use case for mouseenter and mouseleave. I submitted a patch
for it; it is scheduled to be part of Prototype 1.6. (see
http://dev.rubyonrails.org/ticket/8354)
Without the patch, you can add the code below to the beginning of your
mouseover and mouseout functions so that mousing over and out of child
elements has no effect.
--Ken Snyder
onMouseOver: function(event) {
var currentTarget = this.container;
var relatedTarget = $(event.relatedTarget || event.fromElement);
if (relatedTarget==currentTarget ||
relatedTarget.childOf(currentTarget)) return;
...
},
onMouseOut: function(event) {
var currentTarget = this.container;
var relatedTarget = $(event.relatedTarget || event.toElement);
if (relatedTarget==currentTarget ||
relatedTarget.childOf(currentTarget)) return;
...
}
