UserJS to omit redirections in 2ch BBS.

2ch.js

addEventListener("DOMContentLoaded", function(){
	if(location.hostname.indexOf(".2ch.net", location.hostname.length - ".2ch.net".length) === -1) return;
	var a = document.getElementsByTagName("a"), i;
	for(i = 0; i < a.length; i += 1) a[i].href = a[i].href.replace(/:\/\/ime\.nu\//, "://");
}, false);

You should definitely make this into an extension!

Just a couple of things you could change if you like:

addEventListener("DOMContentLoaded", function(){
    if(location.hostname !== '2ch.net') return;

    var a = document.getElementsByTagName("a"), i;
    for(i = 0; i < a.length; i += 1){
        a[i].href = a[i].href.replace(/:\/\/ime\.nu\//, "://");
    }
}, false);

Good. I will employ your idea :)

I found out that String.indexOf is slightly faster than String.match. Interesting.

Applied more updates to hostname matching, according to my speed test (http://tomato.myftp.org/blog/post?id=186).
