如何确定v8中回调的源信息 [英] how to determine source information of callback in v8

问题描述

是否可以确定v8中回调的源信息（文件，行号，列号）？

Is it possible to determine the source information (file, line number, column number) of a callback in v8?

function foo(callback) {
    var x = callback();
    if (typeof x !== "string") {
        //hmmm, x is not as expected, I want to know more about the callback.
    }
}

推荐答案

I 'm不知道你可以在JavaScript中这样做，但如果你可以调试它，它应该显示你的文件/行等。

I'm not aware that you can do this in JavaScript, but if you can debug it, it should show you the file/line etc..

我想这样做完全取决于您的设置，我从来没有做过 - 它看起来像节点（使用v8）有某种支持。

I guess doing that would depend exactly on your setup and I've never done it myself - it looks like node (uses v8) has some sort of support for that .
