JavaScript-DOM Prototypes in Mozilla

Accessing the prototype of an object through the constructor property's prorotype property

And a third way (also per the ECMAScript specification) through which one can access the prototype of an object is through the constructor property's prorotype property:

document.images[0].constructor.prototype.foo = bar;

Note though, the above does not yet work in Mozilla.

We have to find out for which versions this "not yet" worked. --Andreas Wuest 17:13, 10 March 2007 (PST)
