I Cannot Color the Active Page Number When Paginating: A Step-by-Step Solution

Are you frustrated because you cannot color the active page number when paginating? Don’t worry, you’re not alone! Many developers have struggled with this issue, but fear not, dear reader, for we have a comprehensive solution for you. In this article, we’ll take you by the hand and guide you through the process of coloring the active page number when paginating.

Understanding Pagination

Pagination is a crucial aspect of web development, especially when dealing with large datasets. It allows users to navigate through multiple pages of content, making it easier to consume and interact with. However, styling the active page number can be a challenge, especially for beginners.

The Problem: Styling the Active Page Number

So, why is it so difficult to color the active page number? The reason lies in the way pagination works. When you click on a page number, the browser reloads the page, and the active page number is determined by the current URL or query string. This makes it challenging to apply styles to the active page number using traditional CSS methods.

The Solution: Using JavaScript and CSS

Luckily, we can use JavaScript and CSS to overcome this limitation. We’ll create a custom pagination system that allows us to color the active page number with ease. Let’s get started!

Step 1: Create the Pagination HTML Structure

First, we need to create the HTML structure for our pagination system. We’ll use an unordered list (<ul>) to contain our page numbers.

<ul id="pagination">
  <li><a href="?page=1">1</a></li>
  <li><a href="?page=2">2</a></li>
  <li><a href="?page=3">3</a></li>
  ...
</ul>

Step 2: Add JavaScript to Get the Current Page Number

Next, we need to add JavaScript to get the current page number from the URL or query string. We’ll use the window.location object to achieve this.

<script>
  const pagination = document.getElementById("pagination");
  const currentPage = getPageNumberFromUrl();

  function getPageNumberFromUrl() {
    const urlParams = new URLSearchParams(window.location.search);
    return parseInt(urlParams.get("page")) || 1;
  }
</script>

Step 3: Add CSS to Style the Active Page Number

Now, we need to add CSS to style the active page number. We’ll use the :nth-child() pseudo-class to target the active page number.

<style>
  #pagination li a {
    color: #333;
  }

  #pagination li:nth-child(${currentPage}) a {
    color: #009688; /* color the active page number */
  }
</style>

Step 4: Update the Active Page Number on Page Change

Finally, we need to update the active page number when the user navigates to a different page. We’ll add an event listener to the pagination list items.

<script>
  pagination.addEventListener("click", function(event) {
    if (event.target.tagName === "A") {
      const nextPage = event.target.textContent;
      window.location.search = `page=${nextPage}`;
    }
  });
</script>

Conclusion

And that’s it! We’ve successfully created a custom pagination system that allows us to color the active page number. By using JavaScript and CSS, we’ve overcome the limitation of traditional CSS methods.

Tips and Variations

Here are some additional tips and variations to take your pagination system to the next level:

• Use a library like jQuery to simplify the JavaScript code.
• Add a loading animation when the user navigates to a different page.
• Use a different styling approach, such as using a background color or icon.
• Implement infinite scrolling or lazy loading for better performance.
