Imagine two arrays:
[one, two, three, four]
[three, four, five, six]
And I want to end up with [one, two, three, four, five, six] but I
have no guarantee that there aren't some repeated values in there -- I
can't just use Prototype's Array#uniq to do this -- because order of
elements is important. I need the equivalent of lining up two
transparencies on a light table, except with arrays.
That's a very simplified model, let me explain what they really
represent: The first is the base HREF of the page, and the second is a
path to an image file. I need to construct an absolute URI to the
image, regardless of whether it was coded as a root-relative or page-
relative URL in the HTML.
Can anyone suggest a way to do this?
