javascript - 微信jssdk调用的问题，明明已经已经注入成功了，为何这样

<code>public constructor (options?: BodyConfig, page?: JQuery) {

        var _self = this;

        if (options == null) { return; }

            console.log('wx.options is null');
            return;

        }

        wx.config(wecaht_opt);

        console.log(wecaht_opt);
