Display the background-image of the <body> element only when the image has finished loading

I have a webpage where I want to delay showing a large image until it has finished downloading. Instead, I would like to display a background with a fading effect while the image loads.

The challenge is that the background image must be set within the body tag, and I don't want to use jQuery's show/hide functions as they would affect the entire webpage.

I have searched for solutions online but most examples involve showing/hiding elements in different tags, not within the body tag itself.

Is there a way to achieve this, or am I asking for something impossible? Any help would be appreciated!

Answer №1

To dynamically set the background-image of the body once the page has finished loading, you can use the following code:

jQuery('body').css('background-image', 'url(path/to/your/image.jpg)');

You can test it out on this demo: http://jsfiddle.net/exampleuser99/aBcDe/

Answer №2

To begin, you must establish 2 distinct CSS classes: bodyloading and bodyloaded. The former will serve as the body tag's default class name. Once the page finishes loading, you have the ability to modify the body tag's class name to bodyloaded

document.body.className = "bodyloaded";

As a result, the second CSS will be visible (which will include the background image).

Answer №3

When utilizing the code $('body').hide, it will hide the entire element, not just the background image. In other words, nothing will be visible. To solely hide the background image, adjust the css accordingly.

$('body').css("background-image", "url(image.jpg)");

Answer №4

Here are my recommendations to achieve your goal:

  1. First, save the image separately from the document.
  2. Next, use JavaScript to load the image.

  3. Set the image as the background only after it has been fully downloaded (it will be cached, allowing you to simply point the src of the image and it will work)

    var img = new Image();
img.onload = function() { .$('body').css('background-image', 'url(' + http://path/to/image.jpg +  ')'); }
img.src = "http://path/to/image.jpg";

  4. Optionally, execute everything only once the document has finished loading (enclose the function body in: 

    function () { $(ready) { function() { .$('body').css('background-image',                  'url(' +     http://path/to/image.jpg +  ')'); }  }
