用js限制網頁只在微信瀏覽器中開啟
js
$(function(){
//判斷頁面是否是在微信瀏覽器開啟
//對瀏覽器的UserAgent進行正則匹配，不含有微信獨有標識的則為其他瀏覽器
var useragent = navigator.userAgent;
if (useragent.match(/MicroMessenger/i) != 'MicroMessenger') {
window.location.href = "wxError.html";//若不是微信瀏覽器，跳轉到溫馨error頁面
}
})
頁面
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
</head>
<body>
<script type="text/javascript">
var ua = navigator.userAgent.toLowerCase();
var isWeixin = ua.indexOf('micromessenger') != -1;
var isAndroid = ua.indexOf('android') != -1;
var isIos = (ua.indexOf('iphone') != -1) || (ua.indexOf('ipad') != -1);
if (!isWeixin) {
document.head.innerHTML = '<title>抱歉，出錯了</title><meta charset="utf-8"><meta name="viewport" content="width=device-width,user-scalable=0"><link rel="stylesheet" type="text/css" href="https://res.wx.qq.com/open/libs/weui/0.4.1/weui.css" rel="external nofollow" >';
document.body.innerHTML = '<div class="weui_msg"><div class="weui_icon_area"><i class="weui_icon_info weui_icon_msg"></i></div><div class="weui_text_area"><h4 class="weui_msg_title">請在微信客戶端開啟連結</h4></div></div>';
}
</script>
</body>
</html>一般情況下限制頁面被pc端訪問就可以了，那麼就可以參考下面的程式碼了
在需要被pc端訪問的頁面的腳本里加上如下程式碼即可：
<script>
var system = {};
var p = navigator.platform;
var u = navigator.userAgent;
system.win = p.indexOf("Win") == 0;
system.mac = p.indexOf("Mac") == 0;
system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
if (system.win || system.mac || system.xll) {//如果是PC轉
if (u.indexOf('Windows Phone') > -1) { //win手機端
} else {
window.location.href = "提示頁面路徑";
}
}
</script>到這裡就完美了，我們小編專門從電影網站扒的程式碼。
