how to check and bypass an error in scripts....

Hey guys, I've decided to go back and clean up some of the scripts that I use on a regular basis to make them more useful.
I'm sure this is a simple thing but I just don't know how to do it.

So I have a script to save out an image in various sizes/formats/whatever

Theres a specific error I encountered today in the following line of code:

activeDocument.trim(TrimType.TRANSPARENT,true,true,true,true);

After looking into it I found that if there aren't any transparent parts in my image then it stops right there and won't execute the rest of my script.
if I delete that line out it executes just fine.

I want to keep that line in my script for the instances when there are transparent pixels.
How would I go about checking to see if that line of code applies, and if it doesn't, then to simply skip over it and process the rest of the script without it?

Use a try/catch block:

try{
//your code here
}
catch(e){
//leave blank or enter code you want to run if it fails.
}

Perfect! it's so simple lol.

I'd seen those before in other scripts too but hadn't clicked that I could use it to simply block out a line if it didn't work.

Thanks man!

Glad it was a simple fix.
