小程序只選擇年份問(wèn)題

小程序碼

 <view class="time-plugins">
            <picker mode="date" fields="year"  value="{{date}}"  end="{{date}}"  bindchange="bindDateChange">
             {{date}}
            </picker>   
       </view>

  bindDateChange: function (e) {
    var date = e.detail.value; console.log(date);
    this.setData({
      date: date
    })
    this.post_data.year = date;
    this.renderHtml();
  },

在安卓運(yùn)行效果正常
