听取console.log [英] Listening console.log

问题描述

我想为 console.log（）设置一个监听器，并在不阻止默认行为的情况下对该消息执行某些操作。因此，开发工具的控制台也应该得到消息。任何想法？

I want to set a listener for console.log() and do something with the message without preventing the default behaviour. So, the console of the dev tools should get the message as well. Any ideas?

推荐答案

从未在网页上尝试过这个，但它在浏览器插件中工作（javascripts权限不是同样出于安全原因）。

Never tried this in a webpage, but it work in a browser plugin (where javascripts rights are are not the same for security reasons).

你可以明确地采用这样的方式：

You could definitively go for something like this :

(function(){

    var originallog = console.log;

    console.log = function(txt) {
        // Do really interesting stuff
        alert("I'm doing interesting stuff here !");

        originallog.apply(console, arguments);
    }

})();

javascript中有趣的是函数也是对象：D

The funny thing in javascript is that function are objects too :D
