[mochikit] Re: Mapi function
Thanks for the reply, so that answers the alternate rows case, but there are plenty of other cases where you would want to know the index of the item. The items() solution feels like a bit of a workaround and presumably has performance implications. Would a mapi function not be more efficient and elegant? Sorry if I'm missing something.

[mochikit] Re: Mapi function
Did you read the sentence that I wrote? izip(count(), someArray) does the indexes.

[mochikit] Re: Mapi function
Hi Rupert,
You can do that using the MochiKit.Base.items() function:
var foo=[{b:1},{b:2},{b:3}];
var indexed_foo = items(foo); // an array like
[[0,{b:1}],[1,{b:2}],[2,{b:3}]];
Then you can map over this using arg[0] and arg[1] as index and value
respectively.
:)
Regards,
B
Hi there, how about adding a mapi function to Mochikit.Iter which
passes the index of the item being processed to the specified
function? It would be really handy, for instance for specifying
altenate rows on a table.
