Javascript trouble?
Ask the mailing list gurus--
It's Scriptaculous.
I borrowed code sequences from the prototype windows-class add-in
which also
supports dragging. There are a few new things I don't understand.
First
among them is Event.stop() which calls Event.preventDefault(). I
don't see
this in prototype.js. Anyone know what this is? Cancelling the
bubbling I
understand.
From Prototype:
Event.stop = function(event) {
if (event.preventDefault) {
event.preventDefault();
event.stopPropagation();
} else {
event.returnValue = false;
event.cancelBubble = true;
}
}
event.preventDefault() is a DOM event function equivalent to setting
event.returnValue = false in IE or putting "return false;" in an
inline event handler. It prevents the browser's default action (e.g.
form submission, following the link).
