一切福田，不離方寸，從心而覓，感無不通。

微信分享到朋友圈

微信内置浏览器（WebView）中特有的javascript API（javascript Interface），随着微信官方的调整，部分API已经不能直接使用，比如类似直接分享到朋友圈WeixinJSBridge.invoke(shareTimeline,data,callback) 这样的功能，直接调用，会得到一个访问拒绝的response

function WeiXinShareBtn() {
    if (typeof WeixinJSBridge == "undefined") {
        if (document.addEventListener) {
            document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
        } else if (document.attachEvent) {
            document.attachEvent('WeixinJSBridgeReady', onBridgeReady);
            document.attachEvent('onWeixinJSBridgeReady', onBridgeReady);
        }
        alert("请先通过微信搜索 wow36kr 添加36氪为好友，通过微信分享文章 ");
    } else {
        WeixinJSBridge.invoke('shareTimeline', {
            "title": "36氪",
            "link": "http://www.36kr.com",
            "desc": "关注互联网创业",
            "img_url": "http://www.36kr.com/assets/images/apple-touch-icon.png"
        });
    }
}

此方法已过时，被微信禁用了。只能用微信官方的接口
