I watched the new blog on java script errors...
nice...
that said, here's my experience on those next to find impossible java script errors nobody wants to talk about
1 on the list
java script event doesn't work, kaput, nada not even having the first line of alert("hello world"); works..
first thing to do... make sure all your variable names match all the way thru and thru
java script is horrible at this, no way to find but to copy to your favorite editor and start searching / matching...
case in point mis-spell a variable, tough, really tough to find.. unless you know that you 've only touched one place since last compile
read on down about project back up files and how often... will save your bacon...
2 on the list
java script event doesn't work, kaput, nada
well guess what, it probably will work, you just gotta go find the java script that doesn't pass muster
i.e. do the code check on all of em, unless of course you know what you've touched recently, that helps a little
above two issues are bears to find if you are hacking away like made and come up short...
been there got that T shirt, using prior revisions in the code base may help... but... you gotta know where you've been working, etc...
long days, that might not be good
so... my favorite solution... make a back up of the project file, often, really often, like every 10 mins if on a big project with lots of pages often...
will save you lots of heartaches as you can go back and only lose 10 /20 / 30 mins of work and get back to a good working point
cause finding the above two issues is tough really tough
If someone has experience on other ways to find the above two issue, let me know
Hope this helps someone...
Best
