How to call outer function's return from inner function?

Question

I have such code:

function allValid() {
    $(\'input\').each(function(index) {
        if(something) {
            return false; 
        }    
    });

If you want to do this efficiently, I think this is the best way:

function allValid() {
  elements = $('input')
  for (i = 0; i < elements.length; i++) { invalidityCheck(elements[i]) && return false; }
  return true;
}

Edit: Although a more JavaScript-y version would probably use exceptions:

function allValid() {
  try
    $('input').each(function(index)) {
      if (something) { throw 'something happened!'; }
    });
  catch (e) {
    if (e == 'something happened!') {
      return false;
    } else {
      throw e;
    }
  }
  return true;
}
