扩展console.log（）的javascript Web应用程序的客户端日志记录

Question

I have been searching the internet for a clean solution regarding client side logging for a javascript apps and have not come across an obvious choice.

My code is written with console.log() . I was hoping to find a javascript plugin that over-rides console.log() , such that i dont need to change my code, and also extends it so I can do things like programatically get the last 10 log lines to show the user?

Should I just over-ride console.log() in my application so that apart from printing to the console, it saves the logs to a global array?

I am writing mobile web apps.

Yes. You can just override console.log function. Simple example:

var logs = [];
console.log = function(value) {
    logs.push(value);
}

And to access all parameters given to function you can use arguments object .
