Hello.

I'm trying to write a script (My First) for Photoshop.

I want to check a condition and if it's true to exit the script.

The problem I can't find any place writing what is the "Exit" command in a script.

Thanks.

Write your code in a function then you can test for your condition and use return to exit

function main(){

if(someThingIsWrong) return;

}

main();

I wonder if there's an option that if there's no Document, it will just stop running the script.

Something like:

if (!documents.length) {
alerts ("There are no Documents");
Exit (); // A function that stops the script
}

Has anyone succeeded doing it?

How can I write such "Exit" function?

Thanks.

What I do is set up a variable at the very start to shut down things and then have that variable checked to either run the script to stop. so something like this:

var exitProg = false;
if(some condition met){runProg}
else{exitProg = true}
function runProg{
Your code here...
if(another condition checked){
secondFunction()
More code}
else{
exitProg = true;
return}
}
function secondFunction(){
More code here.....
}

By setting the exitProg= true, you can then write your program to skip over everything else and just finish without running any more code.

Thanks csuebele,

I have over 700 line of code and I would really prefer to run the check before start running all of the rest of the code. I would hate to mess-up the code by adding or deleting a forgotten '}' somewhere. If I could just kill the script at the begining after a warning that would be faster to implement, and I think easier to read for my taste. I'm still learning coding, so I'm not too familiar with best practices. But, I think there has to be a way to kill the script if it doesn't meet a condition.
