How to Use JQuery to Dynamically Hide Text and Add a Collapse Button

If you've ever worked on web projects that involve displaying text content, you might have faced a common challenge: managing lengthy text that can disrupt the layout of your page. This can particularly become an issue when the text exceeds a certain amount of lines, resulting in a poor user experience. So, how can you tackle this problem effectively?

In this guide, we'll explore how to utilize JQuery to create a dynamic solution that hides excess text and adds a user-friendly collapse button when the text exceeds five lines. Let’s dive in!

Problem Overview

The objective is clear:

Display only the first five lines of text.

Show a collapse button (or link) when the text exceeds this limit.

Allow users to toggle the full content when they wish to see more.

This functionality not only cleans up the interface but also keeps your web application looking neat and organized.

Step-by-Step Solution

Step 1: HTML Structure

First, let’s lay out the basic HTML structure needed for this functionality. We’ll create a paragraph for the content and a link for the collapse button. Here’s an example:

Step 2: CSS for Text Clipping

Next, we need to add some CSS to limit the visible lines of text. The key CSS properties we'll use include overflow, text-overflow, and display: -webkit-box with -webkit-line-clamp:

Step 3: Adding the JavaScript Functionality

Now we’ll utilize JQuery to handle the logic for toggling the visibility of the text and the collapse button:

How It Works

Setup: We initialize our variables to select the content and collapse button, set the number of lines to show, and calculate the initial heights needed.

Collapse Logic: We check the content height against our set limit. If the content exceeds it, we dynamically adjust the height and show the collapse button.

Toggle Function: On clicking the collapse button, we toggle the text's visibility by either expanding it fully or collapsing it back to the set height, with a smooth animation.

Final Thoughts

Implementing a dynamic collapse functionality using JQuery not only enhances the user experience but also ensures that your web pages maintain an organized and aesthetic appearance. Feel free to experiment with additional styles and customizations as per your project’s needs!

By following this guide, you now have a neat solution to an often overlooked yet critical element in web development. Happy coding!
