Detecting unknown objects & properties?

Is there a way to detect unknown object and their properties, without knowing the object/property names beforehand?

I'm interested in ways to get the code to describe itself, so I can do some research without proper documentation.

Are there set commands for stuff like this or some clever techniques, is it even possible?

Thanks!

Yep, you can do something like this:
function showProps(obj){
var message="";
for(prop in obj){
if(obj.name){
message += obj.name+".";
}
message += prop+"="+obj[prop]+"\n";
}
alert(message);
}

Though you may not like what you find!

Thanks a lot, with a few slight mod's that was exactly what I was looking for!

Why did you think I might not like it?

I seem to remember that looking at certain html objects you end up with tons of properties, most of which are completely irrelevant to what I was after. Perhaps you're after them all, if so great!
