扫描二维码，提示请在指定客户端打开连接

有时候，需要链接只能在微信上打开，如果不是，则提示请在微信客户端打开链接的字眼的网页，网页代码如下：（这个是网页应用授权时，非微信上打开，就会出现，然后把它单独拿出来了）

效果如图：

实现方法：

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=0">
</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">';
                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>

测试代码：

html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<script type="text/javascript" src="../js/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
	//alert(window.location.href);
});

</script>
</head>
<body>
<div>
dsfsdafsadfsdf
</div>
<div>
dsfsdafsadfsdf
</div>
<div>
dsfsdafsadfsdf
</div>
<div>
dsfsdafsadfsdf
</div>
<div>
dsfsdafsadfsdf
</div>
<div>
dsfsdafsadfsdf
</div>

<script type="text/javascript" src="../js/wx_foot.js"></script>

</body>
</html>

wx_foot.js

/**
 * 判断是否在微信内置浏览器内打开
 */
function isWxBrowser(){
	//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);
	return navigator.userAgent.toLowerCase().indexOf('micromessenger') != -1 ? true : false;
}

/**
 * 不是微信则提示
 */
if (!isWxBrowser()) {
	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">';
	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>';
}

完！！！
