Preserved Topic: JavaScript Error Detection ! HELP !

I'm currently studying JavaScript. When there are errors in some code, finding them in order to correct them seems to be impossible. Is there some program or editor that helps with this, gives line numbers or something where the error is?

I don't think I'll ever get through this class unless I can figure out how to efficently find the errors in my coding (and in the books coding!).

In IE: double click the little icon in the lower left of the whole browser window (on the left of the status bar). Then check the checkbox to always display the dialogue box, and click "details".

In NN: Type "JavaScript:" (with the colon) in the address bar.

In Mozilla: Tasks -> Tools -> JavaScript Console.

In Opera: go into the preferences, and look around *very* carefully, it's in there somewhere. In the second half of the list, I think. Look for the option to display JavaScript errors.

--------

If the problem isn't a real error, and it's just a bug, then you'll have to do some debugging. Try putting alert() functions in places to tell you about what's going on in the code, so you can see if something you didn't expect happens.

e-maestro: A lot of the good script editors have a feature with line numbering in and I suspect your best bet is mr.maX's HTMLBeauty:

Without line numbering tracking down the exact line refered to in the error message can be a pain.

WOW!

THX y'all this should be a good start and a big help! I will check it out the options ASAP!

isnt there a way to re-route those error-detections so that you make it call a function that alerts you with the line number and whatsoeve`?
I heard something about that somewhere. I guess I read it in a book...

kars10, we had a long discussion about this long time:

well, that's a lot of stuff. I read through it until this HUGE think "in the name of the JS Bible".
I copied it down and tread through it this evening sitting next the fire and a glass of wine... =)
thanks a lot.
