I work in Aptana. You set breakpoints, hover over variables, and do watches right in the editor. Love it. Never thought I'd move away from Firebug as my chief debugger.
If you're accustomed to using Firebug, you might like Firebug Lite, implemented in JavaScript. You can use it as a bookmarklet, which is nice. I'm not sure how powerful it is, I imagine other, "real" solutions are better, but it's handy in a pinch.
For Internet Explorer debugging (and when you don't have VS 2008), you can use MS Script Editor. This is a good writeup on how to get it configured correctly:
Here is an article, Advanced JavaScript Debugging Techniques, that describes the use of several tools. One new tool I learned about that I hadn't heard of before is JSLint. Sometimes JSLint just immediately shows you your dodgy code that is causing the issue.

我在阿普塔纳工作。 您可以设置断点、将鼠标悬停在变量上并直接在编辑器中进行监视。 爱它。 从未想过我会离开 Firebug 作为我的首席调试员。

如果您习惯使用 Firebug，您可能会喜欢用 JavaScript 实现的 Firebug Lite。 您可以将它用作书签，这很好。 我不确定它有多强大，我想其他“真正的”解决方案会更好，但在紧要关头它很方便。

对于 Internet Explorer 调试（当您没有 VS 2008 时），您可以使用 MS 脚本编辑器。 这是关于如何正确配置它的好文章：

Google chrome 浏览器内置了一个合理的 JS 调试器。 此处提供了可用命令的详细列表。
The Google chrome browser has a reasonable wee JS debugger built-in. There's a good list of the available commands here.
看一下 Venkman，Firefox 的 JavaScript 调试器：
http://www.mozilla.org/projects /venkman/
这是一个真正的源代码级 JavaScript 调试器，您可以在其中设置断点并单步调试代码。
Take a look at Venkman, the JavaScript debugger for Firefox:
http://www.mozilla.org/projects/venkman/
It's a real source-level javascript debugger where you can set breakpoints and step through code.
Aptana Studio IDE 有一个很好的 JavaScript 调试器。
社区版仅支持Firefox，专业版还支持Internet Explorer。
Aptana Studio IDE has a nice javascript debugger.
The community version supports only Firefox, the professional one also supports Internet Explorer.
这是一篇文章，高级 JavaScript 调试技术，描述了几种工具的使用。 我了解到的一个以前从未听说过的新工具是 JSLint。 有时 JSLint 会立即向您显示导致问题的可疑代码。

Opera 有 Dragonfly，不过我仍然更喜欢 Firebug。 在 Firebug 之前就有 Venkman，尽管目前它的未来还不确定。
Opera has Dragonfly, though I still prefer Firebug. Before Firebug there was Venkman, though it's future is uncertain at this point.
