Depending on your needs sometimes you may wish to create a pagination with an array of items. This post will teach you, paginating an array objects in Javascript.
When manually(Without plugins) paginating, you should manually “slice” the array of results into checks. If you’re unsure how to do this, check out the slice JavaScript function.

function Paginator(items, page, per_page) { var page = page || 1, per_page = per_page || 10, offset = (page - 1) * per_page, paginatedItems = items.slice(offset).slice(0, per_page), total_pages = Math.ceil(items.length / per_page); return { page: page, per_page: per_page, pre_page: page - 1 ? page - 1 : null, next_page: (total_pages > page) ? page + 1 : null, total: items.length, total_pages: total_pages, data: paginatedItems }; } |
If you see Paginator() function, it will accept 3 parameters, items, collection of items, page, number of current page, per_page , number of items to be shown in the request.
How to use
As I mentioned above you just have to pass one required parameter and 2 option methods as for the need. Lets take a sample data and check the results as shown below.

Store the response in a variable and access them and loop over the data elements, reaming all you can directly access.

Like it. Perfect for what I need. Great for any arrays you want to page. You should add it to npm.
