有些网站在微信内需要隐藏url,避免同行盗取链接或不想让用户分享.

第一步:页面引入微信JS

<script src='https://res.wx.qq.com/open/js/jweixin-1.2.0.js'></script>

第二步:编写隐藏菜单函数

function onBridgeReady() {
    WeixinJSBridge.call('hideOptionMenu');
}
if (typeof WeixinJSBridge == "undefined") {
    if (document.addEventListener) {
        document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
    } else if (document.attachEvent) {
        document.attachEvent('WeixinJSBridgeReady', onBridgeReady);
        document.attachEvent('onWeixinJSBridgeReady', onBridgeReady);
    }
} else {
    onBridgeReady();
}

两步就可以了
