如何用JS判断当前域名并跳转到指定页面

获取当前请求路径
var href = location.href ;
if(href.indexOf("baidu")>-1){
    //跳转
  location.href = "http://baidu.com";
}

host = window.location.host;if (host=="www.028wz.net") 
{ document.write("<style>")document.write(".head{ background: url(document.write("</style>")}

<script type="text/javascript">
        if (window.location.href.indexOf("www.xt.com") > -1) {
        document.write("<li style='background:none;'><a href='http://www.xt.com/yygk/yyjj/915.html'>介绍</a></li>");
        } else if (window.location.href.indexOf("www.gzxt.com") > -1) {
        document.write("<li style='background:none;'><a href='http://www.gzxt.com/yygk/yyjj/916.html'>介绍</a></li>");
        } else if (window.location.href.indexOf("www.gzxt.com") > -1) {
        document.write("<li style='background:none;'><a href='http://www.gzxt.com/yygk/yyjj/917.html'>介绍</a></li>");
        }        
</script>
