在Chrome中从控制台运行代码时获取堆栈跟踪错误 [英] Getting stack trace for an error when running code from the console in Chrome

问题描述

我从控制台调用一个函数，但是当它抛出一个异常时，我没有收到类似于代码正常执行的堆栈跟踪。

是有一种方法可以修改我的命令（也许用try / catch）让它提供这些信息吗？

澄清：

page.js：

  function otherStuff（）{return ['a'，'b'，undefined，'c']; 
函数doStuff（）{
 var x = otherStuff（）; 
 var z = parseInt（x [2]）; //这将会抛出一个错误
} 
  

page.js

 >其他的东西（）; 
  

我没有收到返回给我的错误的行号。当从页面（而不是控制台）运行它时，我会收到一个行号和一个堆栈跟踪。

解决方案

虽然详细，但会在Chrome JS控制台中打印交互式错误的堆栈跟踪：

  try {
 throw new Error（）; 
} catch（e）{
 console.error（e.stack）; 
} 
  

不幸的是，如果非错误对象被抛出。

I am calling a function from the console but when it throws an exception I do not receive a stack trace like I would if the code was executed normally.

Is there a way I can modify my command (perhaps with try/catch) to have it provide me this information?

to clarify:

page.js:

function otherStuff() { return ['a','b',undefined,'c'];
function doStuff() {
    var x = otherStuff();
    var z = parseInt(x[2]); // this will throw an error
}

console, after loading a html page that links page.js

> otherStuff();

I get no line number from the Error that is returned to me. When running it from the page (instead of the console) i would receive a line number and a stack trace.

解决方案

Although verbose, this will print the stack trace of an interactive error in the Chrome JS console:

try { 
    throw new Error(); 
} catch (e) { 
    console.error(e.stack); 
}

Unfortunately this won't work if a non-Error object is thrown.
