pagination logic in calculating total of pages

Divide total_items by limit, and round the value up.

Math.ceil(total_items/limit);50 items / 10 per page = 5 pages55 items / 10 per page = 6 pages

javascript reactjs algorithm pagination

you need to check if there is a quotient from the divide operation because there is apparently few items need to be showed in another page

for example:

6 items5 limit

if we just divide and ceil we will get 1 which is incorrect because there is one item need an extra page to be counted

totalPages_pre = (total_items/limit)totalPages = (search.total % page_size) == 0 ? totalPages_pre : totalPages_pre + 1
