[mochikit] Mapi function

[Rupert Bates]

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.

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

Typically this is done with count or cycle and izip.

izip(cycle([odd, even]), someArray)
