Which is the proper JS hotlinking code?

[Videogamer555]

All 4 of the below pieces of code have the same linking affect, with no differences that I can see (I'm using the latest version of Firefox as my browser), but one of them must be the "correct" technique.

<img src="mypic.jpg" onclick="document.location='http://www.google.com'" />

<img src="mypic.jpg" onclick="window.location='http://www.google.com'" />

<img src="mypic.jpg" onclick="self.location='http://www.google.com'" />

<img src="mypic.jpg" onclick="location='http://www.google.com'" />

Which one is the official correct techniuqe for using JS for turning a part of a web page (such as an image) into a link?

The best idea would be to wrap the <img> tag in an anchor:

<a href="http://www.google.com/"><img></a>

In Javascript, document.location doesn't exist, window.location and location are the same thing, self.location has to do with frames which you shouldn't need to worry about.

Even though it works to set the entire location object to a string, you should actually set window.location.href.
