alias to chrome console.log
I would like to know why the follow code doesn't work in the Google Chrome:
// creates a xss console log
var cl = ( typeof( console ) != 'undefined' ) ? console.log : alert;
cl('teste');
output: Uncaught TypeError: Illegal invocation
thanks.

Apparently you can also defined log:
log = console.log.bind(console);
and then the line numbers also work
When you write cl();
, you're calling log
in the global context.
Chrome's console.log
doesn't want to be called on the window
object.
Instead, you can write
cl = function() { return console.log.apply(console, arguments); };
This will call log
in the context of console
.
Unfortunately @SLaks answer isnt applied to IE because it uses window-object as context in console.log-method.
I would be suggest another way that doesnt depend on browser:
!window.console && (console = {});
console.debug = console.debug || $.noop;
console.info = console.info || $.noop;
console.warn = console.warn || $.noop;
console.log = console.log || $.noop;
var src = console, desc = {};
desc.prototype = src;
console = desc;
desc.log = function(message, exception) {
var msg = message + (exception ? ' (exception: ' + exception + ')' : ''), callstack = exception && exception.stack;
src.log(msg);
callstack && (src.log(callstack));
//logErrorUrl && $.post(logErrorUrl, { message: msg + (callstack || '') }); // Send clientside error message to serverside.
};
