Use Your Browser to Edit Any Live Web Page Using a Single Line of JavaScript

This was just too juicy to pass up. Blogstorm recently blogged about an easy JavaScript technique for making any website editable. After checking it out for myself, I just had to share it here at Perishable Press. Here it is:

javascript:document.body.contentEditable='true'; document.designMode='on'; void 0

Paste that single line of code into the address bar of any modern browser and have fun editing the page. Obviously, any changes will only apply to the page as seen in your browser, not the original document. Even so, it’s a fun trick to play around with, snap screenshots, be creative, etc.

Go ahead — amaze your friends!

  1. Hi Jeff,

    Cool trick! I do that with Firebug all the time, which not only lets you edit text, but everything (but you already know that, of course, just letting the other readers know). And I use it often to make that field on the adwords keyword tool a lot bigger than it is (3em height only).

    The only thing I didn’t use Firebug for, is to amaze my friends. Thanks for the idea! I’m going to be so cool now! 8-D
