How to correct JavaScript code

Copy linkTweet thisAlerts:
Aug 11.2009

I am a Web Design teacher, as part of my program I teach JavaScript. My students do their assignments and most times they do not work. After reviewing the code it looks correct. I am thinking that they are using the backspace to make corrections and this is causing them problems but I am not sure. If I cut and past my code into there it works. Can anyone help me with this issue?

Thanks,

If code doesn't work, the first thing that the students should be taught to do is to check the error console.

You do know about the error console don't you teacher?

@TheBearMayAug 12.2009 — In spite of Sterling's somewhat obnoxious reply, he is correct in that the resulting code is what matters, not how it got there. Using the backspace in an editor doesn't normally leave any trace of how the character was erased, just that it isn't there any more.

I personally use this site http://www.jslint.com/ (Javascript Validator), and really try my best to conform to their rules/suggestions.

Success!
