In chrome, safari, and opera setting the background image to an absolute reference such as: "/images/image.png" changes it to "http://sitepath/images/image.png".

It does not do this in firefox.

Is there any way to avoid this behavior, or is it written into the browser's javascript engine? Using jquery to set the background-image also does this problem.

The problem is that I am posting the HTML to a php script that needs the urls in this specific format. I know that setting the image path relative fixes this, but I can't do that.

The only other alternative would be to use a regexp. to convert the urls.

Thanks.

Test this in firefox, and chrome / webkit browser:

<script type="text/javascript" src="/javascripts/jquery.js"></script>
<script type="text/javascript">
    $(document).ready(function(){
        $("#test").css('background-image',"url(/images/images/logo.gif)");
        alert(document.getElementById('test').style.backgroundImage);
    });
</script>
</body>
</html>
