How to "stop" a script from executing?

[hstraf]

I've looked around, but I can't seem to figure this out.

I simply want to have a conditional exit in my javascript..

ie:

if (some condition) {
exit the script}

Is it possible to do this?

I've found return, break, etc.. but I can't find an exit command.

Thanks!

Break should do what you want. That will stop the script cold ...

Although not what you were asking, and i agree completely with Maelstrom's answer, it might also be worth noting that JS no longer needs nesting in singular statements.

if (killme) break;

This still works to break the system.

It actually works by stopping the parser at the current breakpoint (i believe).

I've tried placing break in an if statement but get an error message saying I can't use it outside of a loop.

So the following won't work

 function correct() {
if (alreadyanswered == false){
alert ("alreadyanswered= " + alreadyanswered + "The question has not yet been answered");
alreadyanswered = true;
alert("Correct!  var alreadyanswered= "+ alreadyanswered); 
}else{
alert("This question has already been answered");
break();
}
}

break wont exactly stop a script from executing as this will continue to goto an outside loop, so an if statement inside a for loop would continue until the for loop is finished, you may want to try 'return' as this will pass the variable back to the place it was called and stop the function.
