Question

I would like to trigger an event after a background-image is FULLY loaded.
The image is made from a dynamic PHP script.

$("#box").css("background-image","url(image.php)");

maybe I can try to get the image in a invisible <img> and when the image load (.load())
set the background-image with the src of that invisible <img> ? not sure…

thank you for your help.

You could use my jQuery plugin called waitForImages that would help with this…

$("#box").css("background-image", "url(image.php)").waitForImages({
   waitForAll: true,
   finished: function() {
       // Background image has loaded.
   }
});

Otherwise, to do it manually…

var image = 'image.php',

    img = $('<img />');

img.bind('load', function() {
     // Background image has loaded.
});

img.attr('src', image);

$('#box').css('background-image', 'url(' + image + ')');
