Pluck enumeration itt

[kstubs]

How do you pluck the enumeration itt value?  I need to find an item within an enumeration, but I just need it's index.

$A(['foo','bar','baz']).each(function(elm,idx){
if(elm == 'bar') alert(idx);
});

OK, that is exactly what I wrote.  I'm always looking for that really snazzy shortcut.

Thanks.

For Enumeration (Hash, ObjectRange etc.) use Enumeration#each

var index = -1;
enumeration.each(function(e, i) {
  if (e === 'bar') {
    index = i;
    // looking for the first occurrence
    throw $break;
  }
});

for Array you can use shorter

var index = ['foo','bar','baz'].indexOf('bar');
