mint-ui的mt-datetime-picker日期/時間選擇器的問題,??
每次挑選完日期或是時間!!
再去挑選的時候,竟然不是原來得日期/時間

或者是推薦的手機用的日期/時間挑選器...
感謝大家回復

問題如下圖所示

找到問題了
原來是初始值錯誤

var yy,mm,dd;

console.log("this.pickerValue1=>"+this.pickerValue1);

yy=this.pickerValue1.substr(0,4);
mm=this.pickerValue1.substr(5,2);
dd=this.pickerValue1.substr(8,2);

console.log("this.pickerValue1=>"+yy+" - "+mm+" - "+dd);

this.dateValue1 = new Date(yy, mm -1 , dd, 1, 30, 15);

console.log(this.dateValue1);

this.$refs.picker1.open();
