observe_field is not working everytime in IE 6.0
...ine in Fire Fox but in
IE 6.0 it is not populating second drop down every time.
I read in on of the blog and I have made changes in
prototype.js to get it worked. I have added code mentioned below in
Event Observer function of protype.js file.
Previously my prototype.js like this
registerCallback: function(element) {
if (element.type) {
switch (element.type.toLowerCase()) {
case ''checkbox'':
case ''radio'':
Event.observe(element, ''click'',
this.onElementEvent.bind(this));
break;

extending an existing DOM object in a prototype way
...iveSpan class extend it with some functionality (like
onclick events, attributes, etc)
here''s what I have in mind, but I''m not sure this is exactly correct:
var ActiveSpan = Class.create();
ActiveSpan.prototype = {
initalize: function(span) {
Object.extend(span, this);
this.registerCallbacks();
},
registerCallbackss: function() {
Event.observe(this, ''click'', clickHandler.bindAsEventListener(this);
},
clickHandler: function(e) {
this.style.background = "red";
}
}
does this look right? Also, I''ll eventually want to go through the
child ele...

prototype EventObserver on radio option elements
Hi all,
I just started using prototype 1.3.1. I''ve successfully used
Form.Element.EventObserver on a select list and recently tried to add it
to radio options. However, I think there is a flaw in how it works with
radio options.
Radio options are a little unusual in that there are multiple distinct
elements, tied together by a common name, where changing one element
