Breaking out of a PrototypeJS .each() loop

Question

In this very contrived example, I have an array with 3 elements that I\'m looping over using the .each() method.

var vals = $w(\'foo bar baz\'); 

vals.each( func         


        

Answer 1

if( val == 'bar' ) {
    throw $break;
}

It's documented at the same page you linked. It's an exception specially handled by the each function. When thrown, it prevents your function from being called on further elements.
