prototype.js won't load due it clobbering "Element"
Reported by nickg | March 15th, 2010 @ 10:16 AM
prototype.js has the following gem:
(function() {
var element = this.Element;
this.Element = function(tagName, attributes) {
attributes = attributes || { };
tagName = tagName.toLowerCase();
var cache = Element.cache;
if (Prototype.Browser.IE && attributes.name) {
tagName = '<' + tagName + ' name="' + attributes.name + '">';
delete attributes.name;
return Element.writeAttribute(document.createElement(tagName), attributes);
}
if (!cache[tagName]) cache[tagName] = Element.extend(document.createElement(tagName));
return Element.writeAttribute(cache[tagName].cloneNode(false), attributes);
};
Object.extend(this.Element, element || { });
if (element) this.Element.prototype = element.prototype;
}).call(window);
This effectively wipes out envjs's Element. Here's the trace
nickg-macbook:env-js nickg$ ./tester.sh

By renaming envjs's Element to _Element it was able to load correctly. But that's ghetto.
Namespaces? Modules?
