微信小程序 滾動選擇器(時間日期)詳解
微信小程序自己封裝了很多控件,用起來確實很方便,如果這是Android里面,還需要自己去定義,不廢話,效果圖:

看下相應的屬性:

Page({ data: { dates: '2016-11-08' , times: '12:00' , objectArray: [ '中國' , '英國' , '美國' ], index: 0, }, // 點擊時間組件確定事件 bindTimeChange: function (e) { console.log( "誰哦按" ) this .setData({ times: e.detail.value }) }, // 點擊日期組件確定事件 bindDateChange: function (e) { console.log(e.detail.value) this .setData({ dates: e.detail.value }) }, // 點擊城市組件確定事件 bindPickerChange: function (e) { console.log(e.detail.value) this .setData({ index: e.detail.value }) } |
代碼很簡單,分別綁定事件,點擊切換就Ok。
