Fade background image in and out with jQuery?

So far, I've tried a bunch of things to the effect of the following, without success:

<script type="text/javascript">
var x = 0;

while (true) {
    /* change background-image of #slide using some variation
    of animate or fadeIn/fadeOut with or without setTimeout */
    x++;
}
</script>

Any ideas?

Solution

  • You can fade background colors but not background images. The way to work around this is to have your images as <img> tags and hide them by default display:none;. Give your images position:absolute and z-index:-1 so they act like backgrounds and are behind everything else.

    Here's a quick example of images fading one after the other.

    HTML

    <img src=".." />
<img src=".." />

    CSS

    img{
 position:absolute;
 z-index:-1;
 display:none;
}

    jQuery

    function test() {
    $("img").each(function(index) {
        $(this).hide();
        $(this).delay(3000* index).fadeIn(3000).fadeOut();
    });
}
test();
