Question

I have the following figures to work with:

totalItems = 26;
itemsPerPage = 6;
currentItem = 17;

currentPage = ?? 

Given those figures (or any current item value), how can I determine what the current page is. I think I need to use the modulus function but I can’t fathom out which way to go about it.

Could anyone help please? Thank you

Answer 1

You need the ceil function

//In javascript
currentPage=Math.ceil(currentItem/itemsPerPage);//=3
//17/6=2.8333.. ceiling (round up to nearest integer) = 3

It’s worth pointing out this is assuming 1 based paging (first page is page 1 not page 0) and 1 based item number (meaning page 1 has items 1-6, page 2 has items 7-12).
