Javascript行号映射 [英] Javascript line number mapping

问题描述

格式错误的评论会改变某些浏览器中报告的javascript错误行数;它们看起来像这样：

Magically formatted comments will change the reported line number of javascript errors in some browsers; They look like this:

//@line n "f"

n 是行号， f 是文件名。很遗憾， // @ line 似乎是不可访问的。有谁知道这个功能的文档在哪里，哪些浏览器支持它？

n is the line number and f is the file name. Unfortunately, //@line appears to be ungoogleable. Does anyone know where there is documentation on this feature, and which browsers support it?

（我发现它的引用这里和这里。）

(I found references to it here and here.)

推荐答案
