選擇器用mode來(lái)區(qū)別,默認(rèn)是普通選擇器,e.detail.value拿到的值是選擇了項(xiàng)的索引index,再通過(guò)array拿到值.在data里面做初始化的時(shí)候,將備選項(xiàng)加入array即可.

選擇時(shí)觸發(fā)bindPickerChange事件,獲取index.

②時(shí)間選擇器

mode = time時(shí),是時(shí)間選擇器.start,end分別是有效時(shí)間范圍的開(kāi)始和結(jié)束.格式hh:mm

選擇時(shí)觸發(fā)bindTimeChange事件,獲取time.

③日期選擇器

mode = date時(shí),是時(shí)間選擇器.start,end分別是有效日期范圍的開(kāi)始和結(jié)束.格式y(tǒng)yyy-MM-dd

選擇時(shí)觸發(fā)bindDateChange事件,獲取date
