PHP's exit; in Javascript?

Question

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, Nov 24 '18 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. – David Spector Nov 24 '18 at 16:19

I would finish a function early with a return statement:

return;

Only skipped the function and some of the script still ran for me. – Jamesking56 Sep 04 '12 at 11:45

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.
