6 minutes read

To add a loading image for an iframe, you can use JavaScript to manipulate the iframe element. First, you can create an image element for the loading image and set its source to the URL of the desired image.

Additionally, you can adjust the positioning and styling of the loading image using CSS to ensure it appears correctly on the page.


What is a loading image preload for iframe?

A loading image preload for an iframe is a technique used to display a loading image or spinner while an iframe content is being loaded.

By preloading the loading image, it ensures that the image is shown immediately when the iframe starts loading, giving a better user experience.


How to create a custom loading image for iframe?

To create a custom loading image for an iframe, you can follow these steps:

  1. Create or download an image that you want to use as the loading image. Make sure the image is in a format that is supported by web browsers, such as PNG or JPG.
  2. Add the image to your website's assets folder or any location where it can be easily accessed.
  3. Use CSS to style the loading image. You can set the image as a background image, adjust its size, position, and add any other styles to make it visually appealing.
  4. Create a loading message or spinner using HTML and CSS if you would like to display a textual message along with the image.
  5. Embed the iframe into your webpage and include a loading placeholder in the iframe's src attribute. This placeholder could be a blank HTML file, a loading spinner GIF, or any other loading animation you prefer.
  6. Use JavaScript to remove the loading placeholder and display the custom loading image when the iframe content is fully loaded. You can achieve this by listening for the iframe's load event and then hiding the loading placeholder and displaying the custom loading image.


By following these steps, you can create a custom loading image for your iframe that enhances the user experience on your website.

</head>
<body>
  <div id="loader" class="loader"></div>
  <iframe id="iframe" src="https://www.example.com" style="display:none;"></iframe>
  
  <script>
    window.onload = function() {
      var iframe = document.getElementById('iframe');
      var loader = document.getElementById('loader');
      
      iframe.onload = function() {
        loader.style.display = 'none';
