I've just had some extra stuff put in a URL because I've added a function to Object's prototype.

Perhaps


for(key in params){
buf.push(encodeURIComponent(key), '=', encodeURIComponent(params[key]), '&');
}


should be


for(key in params){
if (params.hasOwnProperty(key)){
buf.push(encodeURIComponent(key), '=', encodeURIComponent(params[key]), '&');
}
}


Although, I can see people passing real, functional Objects to have their properties passed back to the server, so possibly:


for(key in params){
if (params.hasOwnProperty(key)){
var v = params[key];
if (typeof v == 'function')
{
if (key.startsWith("get"))
key = key.substr(3);
else if (key.startsWith("is"))
key = key.substr(2);
v = v.call(params);
}
if (typeof v == 'string')
buf.push(encodeURIComponent(key), '=', encodeURIComponent(v), '&');
}
}


where


String.prototype.startsWith = function(prefix)
{
return this.substr(0, prefix.length) == prefix;
}


BTW, just noticed the resizable textbox! Nice one!

There are lots of things going to break if you mess with the Object prototype. Is there any reason that you are? It is generally considered bad practice.

I have to go thru the scripts and find all for...in loops and clear this up for the next release.

I've added an isInstanceOf() method which goes up the superclass chain created by YAHOO.extend()

That way, I can check if any container passed to my AspicioList constructor to hold the list is an instance of YAHOO.widget.Panel. It will probably be a subclass, but if it's a Panel, I know to create the container Element from its body property. If it's not, then it might be an Element, an HTMLElement, or a String id, so I can create the container Element directly.

I suppose it should just be a static method "isInstanceOf(obj, class)" rather than a method of Object, but it seems like it should be there!

I agree instanceOf should be there. I once created one myself and got rid of it quickly. Instead I use:

Object.instanceOf = function(obj, targetClass){...}

The couple additional keystrokes to keep default object literals intact was worth it IMO.
