公司网站有 PC版本和Web，需要在PC判断设备类型，如果是移动端访问就要跳转到web页面，感觉经常会用到，这里也存一份。
条件判断如下：
document.write("用户代理: " + navigator.userAgent);
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){
<#if siteProjectUrl?? && (siteProjectUrl?length>0)>
location = "${(siteProjectUrl)!''}";
</#if>
}
if (!(bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM)) {
//跳转到pc版
<#if siteProjectUrl?? && (siteProjectUrl?length>0)>
//location = "${(siteProjectUrl)!''}";
</#if>
}
}
//根据设备跳转
browserRedirect();
