监听控制台.log

2022-01-11 00:00:00 logging console javascript devtools

我想为 console.log() 设置一个侦听器，并在不阻止默认行为的情况下处理消息.因此，开发工具的控制台也应该收到消息.有什么想法吗?

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

从来没有在网页中尝试过这个，但是它可以在浏览器插件中工作(出于安全原因，javascripts 权限并不相同).

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

你绝对可以这样做:

(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 的有趣之处在于函数也是对象:D

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