web网站判断是否是PC浏览 js验证

在网站判断客户端的访问方式：（PC 还是 移动）  js代码如下

<script type="text/javascript">

function browserRedirect() {

var sUserAgent = navigator.userAgent.toLowerCase();

var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";

var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";

var bIsMidp = sUserAgent.match(/midp/i) == "midp";

var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";

var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";

var bIsAndroid = sUserAgent.match(/android/i) == "android";

var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";

var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";

if (!(bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM)) {

alert("PC");
window.location.href = "XXXX"; //需要重新加载的页面

} else {

alert("iphone");

}

}

browserRedirect();

</script>
