Recently I received an email from Gary who tried out my shareware Javscript editor, ScrypTik. I tried to reply directly, but his email bounced. Gary's question was a good one, so I'll answer it here as it may help others. Question:
I have downloaded a copy of ScrypTik and I like what it can offer. However, I have the following issue which is typical of my application:
What is the best way of locating the error with your product?
Thanks for your interest in ScrypTik. The easiest way to locate this error is to "view source" in your browser. Then copy this plain text into an editior that shows line numbers (such as ScrypTik), then you can see what is on line 706. Firefox with the HTML tidy plugin does this with view source. Also the Firefox error console will give you a display of the line of code that is giving the error. When developing, I always use Firefox. The firebug plugin is fantastic for AJAX debugging and css issues.
Basically, avoid using IE except for testing how your pages look. This should be done every hour so if (when!) something breaks, you have a good idea of what caused it.
