js判断是否是移动端 访问移动端网址

1以下为代码，可放置在网站foot底部文件，或者haead顶部文件，建议将代码放在网站顶部，这样可以实现手机访问立即跳转！

<script src="http://siteapp.baidu.com/static/webappservice/uaredirect.js" type="text/javascript"></script><script type="text/javascript">uaredirect("http://m.jiuquan.cc");</script>

将代码网址部分改成你网站的手机网址就Ok,当然可以是任意网址！

这应该就是传说中的WAP自动跳转吧！

    if(navigator.platform.indexOf('Win32')!=-1){ 

    //pc

        //window.location.href="电脑网址";

     }else{ 

   //shouji

        window.location.href="手机网址";

      }
