Is there a JavaScript equivalent of Java's

class.getName()

?

No.

But here are various hacks that all fall down in one way or another:

Here is a hack that will do what you need - be aware that it modifies the Object's prototype, something people frown upon (usually for good reason)

Object.prototype.getName = function() {
var funcNameRegex = /function (.{1,})\(/;
var results = (funcNameRegex).exec((this).constructor.toString());
return (results && results.length > 1) ? results[1] : "";
};

Now, all of your objects will have the function,

getName()

, that will return the name of the constructor as a string. I have tested this in FF3 and IE7, I can't speak for other implementations.
