What is the equivalent of PHP's exit; in Javascript/jQuery?
I need to stop my script early depending on certain conditions... The only answers I could find from search was stopping forms from submitting...

In PHP, exit() can be called anywhere. In JavaScript, return can only be called in a function, not in file scope.David Spector– David Spector2018-11-24 16:16:09 +00:00Commented Nov 24, 2018 at 16:16

You could try:
throw "stop execution";
Using return you will skip the current function, that's why throwing is more similar to PHP exit();

When I tried this I got an "uncaught exception" error. In PHP, I believe, exit() stops without error.
I would finish a function early with a return statement:
return;

Only skipped the function and some of the script still ran for me.
A javascript function is terminated by calling return. Usually you will be in the context of a function or something. Also event handlers (like for onclick on an element) will behave like a function and accept return.

From looking on your certain problem, and for everyone else. Please see this. This MIGHT help you.
Just put this one line
if(exit_condition!=true)
and also this requires your codes to be inside of
$(document).ready()
if(exit_condition!=true)
$(document).ready(function() {
// Your code
// Your code
// Your code
// Your code
});
I have also encountered this issue, @Jamesking56 has encountered. And this is my solution.
