How to select first several items using prototype select method?

Question

I have a code like this:

$('my-id').select('dd');

But it selects all dd from 'my-id' block. What is the best way to select only several, for example, 4 dd's from my-id?

Answer 1

Use .eachSlice() to break the array into chunks and then take the chunk you want to work with. In the example below it is the first one.

var dds = $('my-id').select('dd').eachSlice(4)[0];
