设置一个事件，用来测试
用类似于vue中的this.msg = result.data[1].receiver并不能把值传出去
但是用setData却可以，代码如下

 btnclick:function(){var that = this;wx.request({url: 'http://www.k1998.xyz/kjh/reciever.php',success: (result) => {console.log(result.data);//this.msg = result.data[1].receiver;//console.log(this.msg);that.setData({msg:result.data[1].receiver})}});}
