多域名添加备案号

一个网站绑定多个备案域名，需要访问对应域名，显示对应备案号，只需要在程序页脚文件加入以下代码

<a href="http://beian.miit.gov.cn/" id="BeiAnHao" style="color:#999999;" target="_blank">闽ICP备16xxxxx4号-1</a>
<script>
    var yuming = window.location.host;
    if (yuming == "www.aaaa.cn" || yuming == "aaaa.cn") {
        document.getElementById("BeiAnHao").innerHTML = "闽ICP备16xxxxx4号-1";
    }
    else if (yuming == "www.abc.com" || yuming == "abc.com") {
        document.getElementById("BeiAnHao").innerHTML = "鲁ICP备116xxxxx40号-2";
    }
    else if (yuming == "www.bcd.cn" || yuming == "bcd.cn") {
        document.getElementById("BeiAnHao").innerHTML = "闽ICP备17xxxxx82号-1";
    }
</script>
