我可以在 javascript 中扩展控制台对象(用于重新路由日志记录)吗? [英] Can I extend the console object (for rerouting the logging) in javascript?

问题描述

是否可以扩展控制台对象?

Is it possible to extend the console object?

我尝试了类似的东西:

Console.prototype.log = function(msg){
    Console.prototype.log.call(msg);
    alert(msg);
}

但这没有用.我想通过像 log4javascript 这样的框架向控制台对象添加额外的日志记录，并且仍然使用标准的控制台对象(如果log4javascript 不可用)在我的代码中.

But this didn't work. I want to add additional logging to the console object via a framework like log4javascript and still use the standard console object (in cases where log4javascript is not available) in my code.

提前致谢！

推荐答案

尝试以下操作:

(function() {
    var exLog = console.log;
    console.log = function(msg) {
        exLog.apply(this, arguments);
        alert(msg);
    }
})()
