It turns out that you can put JavaScript in bookmarks just by making the "protocol" part of the URL "javascript".
These bookmarks can consequently be used as a kind of macro to extend the surf and search capabilities of WebBrowsers. Things that bookmarklets can do include:
- Modifying the way you see someone else's webpage
- Extracting data from a webpage
- Searching more quickly, and in ways not possible with a search engine
- Navigating in new ways
Examples:
Instructions:
- Copy the text of the link, say: javascript:alert("foo")
- Create a new bookmark, probably somewhere on your "Personal Toolbar"
- Set the URL to the whole thing -- javascript:alert("foo")
- Enjoy (although that particular one is not very enjoyable).
