JavaScript异常处理-显示行号 [英] JavaScript exception handling - displaying the line number

问题描述

在JavaScript中捕获/处理异常时，如何确定异常发生时的调用堆栈?(以及行号(如果可能的话))

When catching / handling exceptions in JavaScript, how can I determine what the call stack was when the exception occurred? (and also if possible what the line number was)

try
{
    // etc...
}
catch (ex)
{
    // At this point here I want to be able to print out a detailed exception 
    // message, complete with call stack, and if possible line numbers.
}

推荐答案

每个浏览器对此的处理方式都不相同，因此没有通用的方法可以做到这一点.此博客文章具有一些不错的代码，可以为大多数受支持的浏览器转储堆栈跟踪.我认为没有提供行号的好方法.

Each browser handles this differently, so there isn't a universal way to do it. This blog post has some good code to dump a stack trace for most supported browsers. I don't think there is a good way to provide the line number.

如果您要特别调试一个功能，则 Firebug 具有良好的堆栈跟踪功能(vis console.trace()).

If you're looking to debug one function in particular, Firebug has a good stack trace function (vis console.trace()).
