Sometimes you don’t have access to a JavaScript console and need to display console errors some other way. This could be a common case for mobile development. With the below snippet, console errors will appear within alerts real time.
if (typeof console != "undefined")
if (typeof console.log != 'undefined')
console.olog = console.log;
else
console.olog = function() {};
console.log = function(message) {
console.olog(message);
alert('
' + message + '
');
};
console.error = console.debug = console.info = console.log
