How to show and hide text on click of a link using JavaScript


Certainly! In this article, we'll explore how to show and hide text on click of a link using JavaScript.

Showing and hiding text is a common web development feature that can help improve the user experience of your website. By allowing users to reveal additional information only when they need it, you can keep your pages more organized and easier to read.

In this tutorial, we'll create a simple web page with a link that, when clicked, will reveal or hide additional text on the page. Here's how to get started.

Step 1: Set up the HTML

The first step is to create the basic HTML structure of our web page. We'll need an anchor tag that will serve as our "show more" button, and a div that will contain the additional text we want to show or hide.

html
<!DOCTYPE html> <html> <head> <title>Show and Hide Text on Click of Link</title> </head> <body> <a href="#" id="showMore">Show More</a> <div id="moreText" style="display: none;"> <p>This is the additional text that will be revealed when the link is clicked.</p> </div> </body> </html>

In the code above, we've created an anchor tag with an id of showMore and a div with an id of moreText. We've also added some sample text to the div to demonstrate how the feature will work.

Note that we've set the style attribute of the moreText div to display: none;. This will hide the div initially, so that the additional text is not visible when the page loads.

Step 2: Add the JavaScript

Now that we have our HTML in place, we can add the JavaScript code that will show and hide the additional text when the link is clicked. Here's the code:

javascript
<script> var link = document.getElementById('showMore'); var moreText = document.getElementById('moreText'); link.onclick = function() { if (moreText.style.display === 'none') { moreText.style.display = 'block'; link.innerHTML = 'Show Less'; } else { moreText.style.display = 'none'; link.innerHTML = 'Show More'; } return false; }; </script>

In the code above, we first use the getElementById method to get references to our anchor tag and div. We then set the onclick property of the anchor tag to a function that will run when the link is clicked.

The function checks the current display style of the moreText div. If it's set to none, meaning that the additional text is currently hidden, the function sets the display style to block to reveal the text. It also changes the text of the link to "Show Less".

If the display style is not set to none, meaning that the additional text is currently visible, the function sets the display style back to none to hide the text. It also changes the text of the link back to "Show More".

Finally, the function returns false to prevent the link from navigating to a new page when clicked.

Step 3: Test the Feature

With our HTML and JavaScript in place, we can now test the feature by opening the HTML file in a web browser and clicking the "Show More" link. Clicking the link should reveal the additional text, and change the link text to "Show Less". Clicking the link again should hide the additional text and change the link text back to "Show More".

Congratulations! You've just created a simple show/hide text feature using javascript.
