Debugging JavaScript in MAC Safari / Tool to debug JavaScript in Safari

      Safari has inbuilt debug menu for java script. By default it is hidden. Safari's "Debug" menu allows you to turn on the logging of JavaScript errors. To display the debug menu in Mac OS X, open a Terminal window and type:

            defaults write IncludeDebugMenu 1

      To display the debug menu in Safari 3.0 for Windows, use a text editor to add the following to the Preferences.plist file located at C:\Documents and Settings\USERNAME\Application Data\Apple Computer\Safari\Preferences.plist :

            <key>IncludeDebugMenu</key> <true/>

        Safari 1.3 and above supports explicit logging of arbitrary information - similar to Objective-C NSLog() - function by using window.console.log() in your JavaScript. All messages are routed to the JavaScript Console window and show up nicely in a dark green, to easily differentiate themselves from JavaScript exceptions.

                window.console.log("I think therefore I code!"); 
                alert("I think therefore I code!");

        WebKit crew has released a JavaScript debugger tool Drosera to debug javascript in safari.

Happy Programming !!
