How do I print debug messages in the Google Chrome JavaScript Console?
Please note that the JavaScript Console is not the same as the JavaScript Debugger; they have different syntaxes AFAIK, so the print command in JavaScript Debugger will not work here. In the JavaScript Console, print() will send the parameter to the printer.
