How to read from Chrome's console in JavaScript

I would like to put a button in my app, 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.

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

You can't. What's in the console can't be read from JavaScript.

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

console.stdlog = console.log.bind(console);

console.logs = [];

console.log = function(){

    console.logs.push(Array.from(arguments));

    console.stdlog.apply(console, arguments);

}

console.logs contains all what was logged. You can clean it at any time by doing console.logs.length = 0;.

You can still do a standard, non storing, log by calling console.stdlog.
