I needed to page through results in an array and couldn't find any simple pagination functions through the googles, so I wrote this. I hope it's useful!

paginate_array.js

function paginateArray(arr,page_num,per_page) {
  var i,r=[];
  
  if (arr.length < 1) {
    return r;
  }
  
  if (per_page == undefined || per_page == null) {
    per_page = 10;
  }
  
  if (page_num == undefined || page_num == null) {
    page_num = 1
  } else if (page_num < 1) {
    page_num = 1
  } else if (page_num == 1) {
    start_i = 0;
    end_i = per_page;
  } else if (page_num == 2) {
    start_i = per_page;
    end_i = per_page+start_i;
  } else if (page_num > 2) {
    start_i = ((page_num-1)*per_page)-1;
    end_i = start_i+per_page;
  }
  
  for (i=start_i;i<end_i;i++) {
    if (arr[i] == undefined || arr[i] == null) {
      break;
    } else {
      r.push(arr[i])
    }
  }
  
  return r;
}
