Introduction

ScrollPager is a lightweight JavaScript library that enables automatic pagination on web pages. It allows users to load and display content progressively as they scroll, improving overall user experience and reducing server load.

Installation

To use ScrollPager on your website, follow these simple steps:

  1. Download the ScrollPager library from the official website or GitHub repository.
  2. Include the ScrollPager script file in your HTML document using the <script> tag.
  3. Ensure you have a target element on your page that will contain the loaded content.
  4. Instantiate ScrollPager and define the necessary configuration parameters.

Basic Usage

Once ScrollPager is installed and configured, you can start using it with just a few lines of code. Here’s an example to get you started:

“`javascript
// Instantiate ScrollPager
const pager = new ScrollPager({
element: ‘my-container’, // ID of the container element
threshold: 200, // Pixels from the bottom to trigger content loading
url: ‘https://api.example.com/content’, // API endpoint for fetching additional content
callback: (response) => {
// This function is executed after each successful content load
// Use the response object to process and display the loaded content
const content = response.content;
// Manipulate the DOM as needed
},
});

// Start ScrollPager
pager.start();
“`

Configuration Options

ScrollPager offers several configuration options to customize its behavior. Here are the available options:

  • element: String – The ID of the container element that ScrollPager will attach to.
  • threshold: Number – The number of pixels from the bottom of the container to trigger the content load. Defaults to 200 pixels.
  • url: String – The API endpoint for fetching additional content. ScrollPager sends a GET request to this URL to load the content incrementally.
  • callback: Function – A callback function that executes after each successful content load. The callback receives a response object as a parameter, allowing you to process and display the loaded content.
  • loadingIndicator: String or Element – Optional loading indicator element to display while content is being fetched. This can be either a CSS selector or an HTML Element.

Advanced Usage

In addition to the basic usage, ScrollPager provides advanced features to enhance your pagination functionality. Some notable features include:

  • Error handling: You can handle errors during the content loading process and display appropriate messages to the user.
  • Scroll offset: Customize the scroll offset to control at which point ScrollPager triggers the content load.
  • Conditional content loading: Implement custom logic to determine when to load content based on specific conditions.
  • Manual pagination: Enable manual pagination, allowing users to trigger content loading manually instead of relying solely on scrolling.

Examples

Here are a few examples showcasing the various ways you can use ScrollPager on your website:

  1. Example 1: Basic Usage – Simple implementation of ScrollPager with default configuration.
  2. Example 2: Custom Configuration – Advanced usage of ScrollPager with custom options and error handling.
