How To Display Loading Message When An Iframe Is Loading

When you're embedding an iframe on your webpage, it's essential to provide a smooth user experience by showing a loading message when the iframe content is loading. This not only informs your users that the content is being fetched but also keeps them engaged during the loading process. In this article, we'll walk you through a straightforward method to display a loading message while an iframe is loading.

To achieve this effect, we can utilize HTML, CSS, and a sprinkle of JavaScript. Here's a step-by-step guide on how to implement this feature:

1. HTML Structure:
Firstly, let's set up the basic HTML structure. Create a container element that will hold both the iframe and the loading message. For example:

Html

<div class="iframe-container">
  <div class="loading-message">Loading...</div>
  
</div>

2. CSS Styling:
Next, let's style the loading message and container using CSS. You can customize these styles to match your website's design. Here's an example CSS code snippet:

Css

.iframe-container {
  position: relative;
}

.loading-message {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  background: rgba(255, 255, 255, 0.8);
  padding: 10px 20px;  
  border-radius: 5px;
  z-index: 999;
  display: none;
}

3. JavaScript Functionality:
Now, let's add JavaScript to show and hide the loading message based on the iframe loading status. We'll use the `load` event of the iframe to detect when the content has finished loading. Here's a sample JavaScript code snippet:

Javascript

const iframe = document.querySelector('iframe');
const loadingMessage = document.querySelector('.loading-message');

iframe.addEventListener('load', () =&gt; {
  loadingMessage.style.display = 'none';
});

iframe.addEventListener('readystatechange', () =&gt; {
  if (iframe.contentDocument.readyState !== 'complete') {
    loadingMessage.style.display = 'block';
  }
});

4. Putting It All Together:
By combining the HTML, CSS, and JavaScript snippets above, you can now seamlessly display a loading message while your iframe content loads. Feel free to modify the styles and messages to suit your website's aesthetic and tone.

In conclusion, adding a loading message to your iframes enhances user experience by providing feedback on content loading progress. With a bit of HTML, CSS, and JavaScript, you can easily implement this feature and keep your users engaged while they wait for the iframe content to load.

That's it! Implement these steps on your website, and you'll have a sleek loading message displayed whenever your iframes are fetching new content. Happy coding!
