[...] would be much cooler if we could use those techniques in all modern browsers. Luckily Erik Arvidsson already gave us his version of JS Generics back in 2006(!) I also found a demonstration of crossbrowser generics in Dan Webb’s Scripting [...]

[...] Bisna grows so much that it’s not unrecognizable. A large set of JavaScript objects were created, some code is not my own creation, I can tell you; but the result is really impressive. Bisna pretends to be a new PHP framework in the future (and if I have enough time). Now it’s only intended to be the replacer for pAjax. So, it’s time to show you how the new code will look like: [...]

Hi,
I’m not as advanced as you are but I am seeing this page with Opera and it throws these errors:

Shouldn’t there be a way to avoid having these errors show in the javascript console?
I may be a bit offbeat…

Call is part of ECMAScript edition 3 and all dialects of JS supports that (or otherwise they are not even worth using).

apply( ) method is implemented in JavaScript 1.2, but the call( ) method is not implemented until JavaScript 1.5. according to the book “JavaScript: The Definitive Guide, 4th Edition”

An Interview with Dean Edwards…

Dean Edwards was kind enough to answer a few questions on JavaScript. Tell me a bit of your background and how you got into JavaScript programming? I’ve been a programmer (professionally) for twenty years. Most of that time I’ve been……

Vincenzo: True and true

I’ve now updated the script.

The quote method has a bug: you have to replace \ with \\
return ‘”‘ + this.replace(/\\/g, “\\\\”).replace(/\”/g, “\\\”") + ‘”‘;

The quirk code can be made more readable in this way:
function extend(constr, name) {
return function (s) {
var args = Array.prototype.slice.call(arguments, 1);
return constr.prototype[name].apply(s, args);
};
}
if (!constr[name]) { constr[name] = extend(constr, name); }

Elegant solution! This is javascript the way I like it!

I have now licensed the file using Apache Software License 2.0. This is compatible with GPL so you can use it in qooxdoo.

The ugly syntax is because constr and name changes during the loop and the extra function actually binds the values to the right values (if this was not done all the methods would do this:

function (s) {
var args = Array.prototype.slice.call(arguments, 1);
return Stringprototype["slice"].apply(s, args);
}

not what one wants
