How do you send console messages and errors to alert?

Question

I would like to pass errors to an alert to warn the user they made mistake in their code even if they don\'t have console open.

    var doc=(frame.contentWin

Ok so the less elegant but highly efficient way of doing this is 'refactoring' your innate console functions. Basically any error or warnings you get are being outputted there by a javascript function that is pretty similar to the familiar console.log() function. The functions that I am talking about are console.warn(), console.info() and console.error(). now let's 're-map' what each of those do:

//remap console to some other output
var console = (function(oldCons){
    return {
        log: function(text){
            oldCons.log(text);
            //custom code here to be using the 'text' variable
            //for example: var content = text;
            //document.getElementById(id).innerHTML = content
        },
        info: function (text) {
            oldCons.info(text);
            //custom code here to be using the 'text' variable
        },
        warn: function (text) {
            oldCons.warn(text);
            //custom code here to be using the 'text' variable
        },
        error: function (text) {
            oldCons.error(text);
           //custom code here to be using the 'text' variable
        }
    };
}(window.console));

//Then redefine the old console
window.console = console;

Now, generally I would highly advise against using something like this into production and limit it to debugging purposes, but since you are trying to develop a functionality that shows the output of the console, the lines are blurry there, so I'll leave it up to you.
