Well, we saw by inspecting a simple code loop doing:
$A(this.elm.getElementsByTagName('A')).each(function(ahref,idx){
if (!Element.hasClassName(ahref.parentNode,'disabled')){
return;
}
}
That hasClassName() in a "slowed" IE take the most part of the time.
Well I know this loop is ugly we should use ?
this.elm.down('A.disabled');
But it is an example. So my question is: should we use Element.hasClassName()
in a loop
or something more straight ?
