                wx.config({
                    debug: false, // 开启调试模式,调用的所有api的返回值会在客户端alert出来，若要查看传入的参数，可以在pc端打开，参数信息会通过log打出，仅在pc端时才会打印。

                    jsApiList: ['onMenuShareTimeline','onMenuShareAppMessage']// 必填，需要使用的JS接口列表，所有JS接口列表见附录2
                });

                wx.ready (function () {
