A cross-browser logging function. Will attempt to use the developer console (i.e.: FireBug) first, and fallback to using alert()
when not detected.
function log() {
try {
console.log.apply(console, arguments);
} catch (e) {
try {
opera.postError.apply(opera, arguments);
} catch (e) {
alert(Array.prototype.join.call(arguments, " "));
}
}
}
// Example
log("here's my log message");
