jquery动态更改svg image xlink：href

我试图用不是填充颜色的图像动态地更改多边形的填充.为此,我找到了一种将填充更改为图像的方法,但是我无法将xlink：href URL动态更改为随机URL.
有什么想法吗？谢谢你的帮助！

 $(document).ready(function() {
                var randomColor = Math.floor(Math.random()*16777215).toString(16),randomNumber = Math.floor((Math.random()*855)+48),backg = $('#background');
                    $("body").css("background-color",randomColor);
                    backg.attr("http://www.w3.org/1999/xlink","xlink:href","url(http://blob.apliiq.com/sitestorage/fabric/" + randomNumber + ".png)");
                    $('a#cta').attr("href","/designyourown/?fabricID=" + randomNumber );               
            });

解决方法

如果您纠正了backg.attr功能属性,则可以正常工作.

$(document).ready(function () {
    var randomColor = Math.floor(Math.random() * 16777215).toString(16),randomNumber = Math.floor((Math.random() * 855) + 48),backg = $('#background');
    $("body").css("background-color",'#' + randomColor);
    backg.attr("xlink:href","http://blob.apliiq.com/sitestorage/fabric/" + randomNumber + ".png");
    $('a#cta').attr("href","/designyourown/?fabricID=" + randomNumber);
});
