Rails spinoffs - Sep 2007 - Prototype Arrays - dont seem to hold values when i insert elemnts by name (not number)

I get a function returned with no contained values when inserting
elements into an array using key''s instead of position (for example):

var x = new Array();
// set ref to id of a form element...
x["control_ref_1"] = "formElement1";
alert($(x["my name"]).value);

If i remove the prototype js reference in my page - it works again. I
have hacked around the problem to work (used Object instead of Array)
- but i would like to know why it works this way. I know that
prototype extends array - but is this a bug - or a specified way to
work? And why?

You should just use Object. You are merely using Object''s behavior with
your
Array instance anyway (i.e. you are not using Array''s special features
at
all so why even bother creating an Array instance).

Arrays should never be used as associative arrays. That''s the rule
you''re
looking for, I think.
