How to Implement Pagination with HTML, CSS and JavaScript

Plus, you improve backend performance by reducing the volume of content retrieved from databases. With Load more, your users have to click actively to load more content. If you want to create a more seamless experience, then you can load more content automatically once your user reaches the bottom of your page.

  • It prevents the creation of new URLs based on the filters that a user chooses.
  • You can play around with different requests to see how it works in other scenarios.
  • If you had already used pagination on your site, there is no need to remove it.
  • Both KeywordListView and listing_api() will work solely with GET parameters.
  • We’ll firstly use JavaScript to divide the table into different “pages” and to add button functionality for navigating through those pages.

For example, maybe you want to serve content dynamically without loading a new page. When you name your Django template keyword_list.html, both your KeywordListView and your listing can find the template. When you enter a URL in your browser, Django will resolve the URL and serve the matched view. When your Django development server is running, you can try out different URLs to see the keyword_list.html template in action.

This means that even if products may be in the same category, their individual description on each product page needs to be different. If you had already used pagination on your site, there is no need to remove it. Sites like e-commerce and news sites have no option but to keep using pagination.

To implement this in our project, we will need a service that has a single responsibility, to build URLs based on the pagination filter passed. Line 12 states that the minimum page number is always set to 1. Line 13 – For this demonstration, we will set our filter such that the maximum page size a user can request for is 10. If he/she requests a page size of 1000, it would default back to 10.

Pagination URLs help the consumer to navigate through the available API Endpoint data with so much ease. Links of the First Page, Last Page, Next page and Previous page are usually the Pagination URLs. We have page size, number, Uris of the first page, last page, total page count, and much more. To implement this feature, we call the updateActiveButtonStates() function whenever a page is changed or displayed.

Page-based pagination involves using a “page” parameter to specify the desired page number. Instead of relying on numeric offsets, cursor-based pagination uses a unique identifier or token to mark the position in the dataset. The API consumer includes the cursor value in subsequent requests to fetch the next page of data. Pagination typically involves the use of parameters, such as offset and limit or cursor-based tokens, to control the size and position of the data subset to be retrieved. These parameters determine the starting point and the number of records to include on each page.

Website pagination comes in handy when you want to split content across pages and show an extensive data set in manageable chunks. Cursor-based pagination excels in efficiently navigating through vast data sets. The way it works is that the API provides a “cursor”—similar to a bookmark—which marks a specific item in the data set. Each request not only retrieves data but also returns a cursor pointing to the start of the next data segment. And while this makes development easier—as the SQL server handles the pagination—it leads to scalability issues.

Both KeywordListView and listing() need templates to render their context. You’ll create this template and the URLs to access the views later in this tutorial. Before you do, stick around in what is pagination for a bit to investigate how a paginated API endpoint works. Finally, in line 15, you call the render() function with request, the template that you want to render, and a context dictionary.

Pagination Logic with JavaScript

You therefore, need to ensure that your paginated pages have unique content and that it is relevant for your users. After implementing pagination on your site, you need to prioritize the most important pages on your home page, or on the page where pagination begins. This strategy will help you effectively optimize your page with all the paginated content (where all results are displayed) so that it can rank high for necessary keywords.

While it provides bidirectional navigation, cursor-based pagination offers limited flexibility as the client can’t easily jump to a specific page. Time-based pagination is a type of keyset pagination used to navigate a data set based on time criteria. It uses timestamps to segment and retrieve records; in other words, the client typically specifies a time range (start and end time) or a reference time point to retrieve records. Beyond just segmenting data, pagination also enhances the user experience and ensures that your API is efficient. Without pagination, users might face long loading times or even timeouts when retrieving large amounts of data.

We’ve added a few more properties, that will come in handy as metadata for our response. The timestamp can be dynamically determined using the last data item in the list. This seems to be more or less how Facebook paginates in its Graph API (scroll down to the bottom to see the pagination links in the format I gave above). However, excessively large page sizes may make it challenging for users to find specific records or navigate through the data efficiently.

The database must scan every row from the beginning to the offset point. As a result, its performance degrades as the offset value increases, making it unsuitable for handling vast amounts of data. There’s also the possibility of navigating to nonexistent pages (e.g. you use an offset value that’s larger than the data set size), which can lead to errors when retrieving data. To do this, provide a unique link to each section that users can click, copy, share and load directly.

In this example, that list includes the numbers 1 to 4, an ellipsis, 17, and 18. When you reach the ellipsis in your list, you don’t want to create a hyperlink. The numbered pages should be hyperlinks, so you wrap them in an a tag in lines 14 to 19.
