How to Implement “View More”/“View Less” Functionality for HTML Tables using jQuery

When it comes to displaying data in a clean and user-friendly manner, HTML tables are often the go-to solution. However, if you have a long list of data, it can be quite overwhelming for users. To maintain a clean interface while still providing access to all necessary information, the “View More” / “View Less” functionality is an excellent solution. In this guide, I’ll show you how to elegantly implement this feature using jQuery.

Understanding the Problem

You have an HTML table that may contain many rows of data, but displaying all those rows at once can clutter the page. Instead, you want to display only a few rows initially and provide users with the option to view more rows when needed. Once they click to view more, the additional rows should appear, and the button text should change to “View Less.” Clicking it again should hide the extra rows and revert the button back to “View More.”

This creates a clean interface while allowing users to expand the information as needed. Let's dive into the steps needed to implement this functionality.

Step-by-Step Guide to Implementation

1. HTML Code Structure

Start with a basic HTML structure for your table. Here is an example:

2. CSS for Hiding Rows

To hide the rows by default, you can use the following CSS:

3. Implementing jQuery Functionality

Now, let’s add the jQuery script that handles the “View More” / “View Less” toggle functionality.

4. Explanation of the Code

Initial Setup: The code starts by defining how many rows will initially be visible. The .active class is assigned to these rows to make them visible.

Click Event: The click event is set up for the “View More” link.

Show All Rows: If the rows are hidden, the script reveals all of them and changes the button text to “View Less.”

Show Limited Rows: If they are visible, it hides all but the original specified rows and resets the button text to “View More.”

Toggle Logic: A simple boolean variable hidden helps in toggling between the two states.

Conclusion

The View More / View Less functionality greatly enhances user experience by making the UI cleaner and more navigable. With just a few lines of jQuery code, you can allow users to easily interact with large datasets without feeling overwhelmed.

Feel free to customize the number of rows displayed based on your needs and adapt the styles as necessary. Happy coding!
