Does prototype not have a method for converting an array to a "x"-
delimited String?
Something like:
("a","b","c").implode("-"); //
"a-b-c"
It wouldn''t be too hard to do by combining toString() and replace(),
but I''m surprised that there is not already a function to do so.

new
Array(''a'',''b'',''c'').join(''-'');
join is standard JavaScript.

No, but there is one built in to the standard Array object: join()
[1,2,3].join(''--'') ==> ''1--2--3''
See e.g., http://www.devguru.com/technologies/ecmascript/QuickRef/array.html

Great! I knew I had to be overlooking something. Thanks Richard!

FYI, "new Array" and "Array" are equivalent : ) - kangax On May 9, 10:47 am, "Richard Quadling" <rquadl...-gM/Ye1E23mwN+BqQ9rBEUg@public.gmane.org> wrote:> new Array(''a'',''b'',''c'').join(''-''); > > join is standard JavaScript. > > 2008/5/9 Keith Hughitt <keith.hugh...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>: > > > > > Does prototype not have a method for converting an array to a "x"- > > delimited String? > > Something like: > > > ("a","b","c").implode("-"); // "a-b-c" > > > It wouldn''t be too hard to do by combining toString() and replace(), > > but I''m surprised that there is not already a function to do so. > > -- > ----- > Richard Quadling > Zend Certified Engineer :http://zend.com/zce.php?c=ZEND002498&r=213474731 > "Standing on the shoulders of some very clever giants!"--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

Thanks. On a side-note. Are there any reasons to use new with a garbage variable in cases like these? JSLint, for example, complains if you try and call a constructor without using "new."

It depends. Array function works the same when invoked as constructor and as a standalone one. String, on the other hand, produces new String object (when invoked as constructor) but does type conversion when called on its own. - kangax On May 9, 4:25 pm, Keith Hughitt <keith.hugh...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Thanks. > > On a side-note.
