Jash: JavaScript Shell

A Cross-Browser Javascript Command-Line Debugging Tool

What is it?


Jash is a DHTML-based window that gives you command-line JavaScript access to the current browser window. With this console you can quickly debug scripts, manipulate the DOM, view the current page's objects, functions, and variables, execute arbitrary Javascript, enter new CSS (in IE, Firefox, Opera, and Safari), and much more.

How do I install it?

Add the bookmarklet to your browser's bookmarks or favorites.
