通过userAgent判断用户是在PC还是在移动端打开网页

HTML标签：

<a href="" id='qq'>点击链接打开QQ聊天窗口</a>

JS代码：

其中

1. "********"替换为QQ号
2. "网址"替换为网页的网址，"域名"替换为网页的域名

// 
function isPC() {
    var userAgentInfo = navigator.userAgent;
    var Agents = ["Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod", "pad", "pod", "ios", "Mobile", "BlackBerry",
    "IEMobile", "phone", "BlackBerry", "IEMobile", "MQQBrowser", "JUC", "Fennec", "wOSBrowser", "BrowserNG", "WebOS", "Symbian", "Windows Phone"];
    var flag = true;
    for (var v = 0; v < Agents.length; v++) {
        if (userAgentInfo.indexOf(Agents[v]) > 0) {
            flag = false;
            break;
        }
    }
    var a = document.getElementById('qq');
    if (flag == true){
        a.href = "tencent://message/?uin=********&Site=网址&Menu=yes";
    }else{
        a.href = "mqqwpa://im/chat?chat_type=wpa&uin=********&version=1&src_type=web&web_src=域名";
    }
}
isPC();
