Update background after all items are loaded

quark

My problem is that my web application loads large images as background. It is applied in <style>the label at the top of the bodylabel. It works, but when opening the page, it shows a white background when the image is loaded.

I wanted to be able to set the image to a specific blue color background-colorwhen loading the image , so I did this:

Before the closing body tag:

     <script type="text/javascript">
        $(document).foundation();
        $(document).ready(function() {
            document.body.style.backgroundImage="url('img/form_bg.jpg')";
            //$('body').css('background-image', 'url(img/form_bg.jpg) no-repeat center center fixed');
        });
    </script>

However, this code won't work and the background won't load. This insists:

body {
    /*background:transparent;*/
    background-color:#2f3255;
}

How can I achieve:

  1. Make background color: #2f3255, when image loads
  2. After loading the image, change the background to the image

You can add an extra div to the DOM ( #intro) which will cover the entire screen when the background image loads:

CSS：

#intro {
   width: 100%;
   position: fixed;
   top: 0;
   bottom: 0;
   z-index: 100;
   background-color:#2f3255;
}

Then, when the page loads, just hide that div:

$(window).load(function() {
    // You could add a time out here if you like (setTimeout(function() { $('#intro').fadeOut();   }, 500))
    $('#intro').fadeOut();    
});
