A Greasemonkey Fix to the Top Menu in Sheilta (Open University)

Following comments in Fixing the Home Link in the Telem System (Open U) I’ve decided to fix the top bar links in the Sheilta system too.

The links in the top bar are javascript links that open in a new window when clicked. My Greasemonkey script turns them into regular links that you can open in a new tab.

tds = document.getElementsByTagName('td');
if (tds) {
	for (i = 0; i<tds.length; i++) {
		if (tds[i].className != "atext") {
			continue;
		} else if (! tds[i].firstChild.attributes) {
			continue;
		} else if (! tds[i].firstChild.attributes.getNamedItem('onclick')) {
			continue;
		}
 
		onclick = tds[i].firstChild.attributes.getNamedItem('onclick').nodeValue;
		re = /window.open\("(.*?)",/
		match = re.exec(onclick)
		if (match) {
			tds[i].firstChild.href=match[1];
		}
		tds[i].firstChild.attributes.getNamedItem('onclick').nodeValue = '';
		tds[i].firstChild.target = '_top';
 
		if (tds[i].firstChild.firstChild.data=='הכימת') {
			tds[i].firstChild.href='/pls/dmyopt2/mabasheilta.hadracha';
		}
	}
}

I hope you will find this script useful. I didn’t find any major bugs, but there may be some. If you find one, please report it to me via the comments or email.

Fixing the Home Link in the Telem System (OpenU)

This post can be helpful for students of the Open University of Israel. As a student there, I found it very annoying that the link to the courses’ homepage in the Telem system is a JavaScript link. This prevents it from opening in a new tab, and thus require various workarounds to get back to the homepage in a different tab. So, a little while ago I wrote a little Greasemonkey script to fix it.

// telem.user.js
// version 0.1 
// 2008-01-01
// Copyright (c) 2008, Guy Rutenberg
// Released under the GPL license
// http://www.gnu.org/copyleft/gpl.html
//
// ==UserScript==
// @name          OpenU's Telem - Fix Home Button
// @namespace     http://www.guyrutenberg.org/
// @description   Fixes the home button link in the telem system of the OpenU.
// @include       http://maagar.openu.ac.il/opus/*
// ==/UserScript==
 
 
home = document.getElementById('home');
if (home) {
	re = /javascript:find_home_page\('(.*?)','(.*?)',/
	match = re.exec(home.href)
	home.href = 'http://telem.openu.ac.il/courses/'+match[2]+'/'+match[1]
}

This script changes the link to a regular non-JavaScript link. I’ve tested it for more than a month now, without finding any bugs. However if you find something, or have any suggestion, please comment.

Update: See A Greasemonkey Fix to the Top Menu in Sheilta (Open University), it has a fix for the top menu bar in the Sheilta system
