如何在JavaScript中通过Chrome浏览器进行阅读 [英] How to read from Chrome's console in JavaScript

问题描述

我想在我的应用程序中放置一个按钮，如果按它，它将获得写入控制台的所有内容并将其发送给我（用于报告错误）。我知道我可以保留一个变量，并且每次执行console.log时都会将消息附加到该变量，但我试图保持应用程序的内存消耗低，因此只需从

I would like to put a button in my app where if you press it, it will get the contents of everything that was written to the console and email it to me (for reporting bugs). I know I can keep a variable around and every time I do a console.log also append the message to that variable but I am trying to keep the memory consumption of the app low so it would be much more efficient just to grab it from the console.

有没有办法从javascript检索控制台消息？

Is there a way to retrieve the console messages from javascript?

谢谢

推荐答案

你不能。

你可以做的是钩住 console.log 函数，以便在日志记录时存储：

What you can do is hook the console.log function so that you store when it logs :

var store = [];
var oldf = console.log;
console.log = function(){
   store.push(arguments);
   oldf.apply(console, arguments);
}
