用js限制网页只在微信浏览器中打开
js
$(function(){
//判断页面是否是在微信浏览器打开
//对浏览器的UserAgent进行正则匹配，不含有微信独有标识的则为其他浏览器
var useragent = navigator.userAgent;
if (useragent.match(/MicroMessenger/i) != 'MicroMessenger') {
window.location.href = "wxError.html";//若不是微信浏览器，跳转到温馨error页面
}
})
页面
<!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，出错了</title><meta charset="utf-8"><meta name="viewport" content="width=device-width, initial-scale=1, 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">请在微信客户端打开链接</h4></div></div>';
}
</script>
</body>
</html>
一般情况下限制页面被pc端访问就可以了，那么就可以参考下面的代码了
在需要被pc端访问的页面的脚本里加上如下代码即可：
<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转
if (u.indexOf('Windows Phone') > -1) { //win手机端
} else {
window.location.href = "提示页面路径";
}
}
</script>
