IE 下的Javascript調試利器:Companion.js

 有用過firebug 的人, 一定會很苦惱 ie下為何沒有這種工具呢?
Companion.JS is a Javascript debugger for IE.
(他是ie 的一個外掛程式, 需搭配MS Script Debugger )

• Detailled javascript error reporting (call stack and real file name where the error occured).
• "Firebug"-like Console API feature.
• Javascript console feature useful to inspect javascript objects at runtime.
• A toolbar icon to open the Companion.JS panel.

這邊下載 (version is 0.5.4.)
這邊有教如何安裝
