Script Debugger

Having trouble adding a JavaScript to your site? Just can't get things working? Add this short script to your site, and it will report to you JavaScript errors as they happen in a box on the screen. The idea is that you will see what the error is, and hopefully give you some ideas on how to fix it. I actually use this script when I debug scripts!

For this example, clicking this button will cause a JavaScript error, that
the function is not defined. The error will be displayed in the box below.

Simply click inside the window below, use your cursor to highlight the script, and copy (type Control-c or Apple-c) the script into a new file in your text editor (such as Note Pad or Simple Text) and save (Control-s or Apple-s). The script is yours!!!
