Is there no better way to merge one array into another than iterating over the
array you wish to append with each() and push()ing the elements on to the
other array?
Here''s what I mean:
var arr1 = [1, 2, 3, 4, 5];
var arr2 = [''a'', ''b'',
''c''];
$A(arr2).each(function(el) { arr1.push(el) });
Is there no better way to do it than this?
Thanks!
-Jeremy

Maybe an alternative: var res = $A([arr1,arr2]).flatten(); hth sigi On 4/24/06, Jeremy Kitchen <kitchen-RA8HwDor7flnDGu+y90WmgC/G2K4zDHf@public.gmane.org> wrote:> > Is there no better way to merge one array into another than iterating over > the > array you wish to append with each() and push()ing the elements on to the > other array? > > Here''s what I mean: > var arr1 = [1, 2, 3, 4, 5]; > var arr2 = [''a'', ''b'', ''c'']; > $A(arr2).each(function(el) { arr1.push(el) }); > > Is there no better way to do it than this? > > Thanks! > > -Jeremy > > > _______________________________________________ > Rails-spinoffs mailing list > Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails-spinoffs > > > >-- Mit freundlichen Grüßen Siegfried Puchbauer _______________________________________________ Rails-spinoffs mailing list Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails-spinoffs

I''ll just stick with the each()/push() iterator for now :) -Jeremy _______________________________________________ Rails-spinoffs mailing list Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails-spinoffs
