A bookmarklet is a little piece of bookmarkable javascript code that can be used to automate the browser in various ways.

The definitive list of bookmarklets can be found at bookmarklets.com

Tips

  • Use void to discard results of an expression, otherwise they may be displayed in the current window
  • Beware of frames
  • Use maximum of ~500 characters unless you use a Bookmarklet Bootloader
  • Use prompt to grap single line of input (possibly multiple times)
  • Use DOM to get access to complete page, and fall back to regexps to parse additional content
  • You can add elements to the DOM, including new attributes, CSS styling and event handlers thereby enriching the original page.
  • Provide different versions of a bookmarklet for different browsers, rather than including browser sniffing directly in the bookmarklet. It'll bloat the code.
  • Udell has an example of setting a cookie from someone elses domain. Hmmm....

MT Bookmarklets aren;t that clever. They just grab the currently selected text (if any), the window title and current location and pass those as parameters to an MT page viewed in a separate window.
