I need to stop my script. I don't want to write more code like if(...) return false because I will use it many times.
My English is poor. It's my first question on this site. :)

It sounds like you want to just kill everything that's running without having to return from every function in the stack? I guess you could throw an exception, which will stop everything (unless the code is in a try ... catch block). That's very messy though, and it will appear as a JavaScript error in the user's browser.Daniel Lo Nigro– Daniel Lo Nigro2013-01-09 06:19:01 +00:00Commented Jan 9, 2013 at 6:19

you can simply write return false; to do so.

OP has already told that he doesn't want to use
return false;. (This is an example, how people answers / upvotes answers without reading the question properly. )In order to exit ALL scopes of your script, you could throw an exception and catch it at the outer scope of your script ;) This imposes, that you adapt your exception handling.
Please note: It is better to write your program in such way, that the following is NOT necessary!
function ExitException() {}
try { //Do your script-stuff here
Foo();
//and do this at any place where you wish to exit:
throw new ExitException;
}
catch (e) {
if (e instanceof ExitException) //This is an Exit. All fine.
console.log("Exit");
else //Pass Exception to the Browser
throw e;
}
