Finding a book in the library

This script can be run on this page. It will insert the availability of the following book in MIT's library system as a link after the author's name.

originalTab = tab;
isbn = find(/ISBN: (\d+)/).groups[1];
with(openTab('http://libraries.mit.edu/', true)) {
  pick('Keyword');
  enter(isbn)
  click('Search button')
  link = find('stacks link')
}
originalTab.show();
insert(after(/^Name:.*/), '<li>' + link.html)

TargetAlert

This script will add an icon to all hyperlinks giving visual information about their final destinations. Hyperlinks that do not point to webpages are appended with icons, eliminating, for example, the "surprise" of arriving at a pdf document.

excludedExtensions = {
  'html' : 1,  'shtml' : 1,  'php' : 1,  'jsp' : 1,  'asp' : 1,
}

mailto = /^mailto:/i
javascript = /^javascript:/i
type = /^[^\\?]*\.(\w+)$/i

for (link = find('link'); link.hasMatch; link = link.next) {
  if (!link.element) {
    output(link.html)
    continue;
  }
  href = link.element.getAttribute('href')
  if (href.match(mailto)) {
    continue
  } else if (href.match(javascript)) {
    html = ' <img src="moz-icon://.js?size=16"> '
  } else if (match = href.match(type)) {
    extension = match[1]
    if (extension in excludedExtensions) continue
    html = ' <img src="moz-icon://.' + extension + '?size=16"> '      
  } else {
    continue
  }
  insert(after(link), html) 
}
