computed:{// 实际结束日期必须选择实际结束日期之后realEndTimeOptions:vm =>{return{disabledDate:time=>{let beginDateVal = `${vm.pmTaskProgressFeedback.realBeginDate}`;if (beginDateVal) {return (time.getTime() <new Date(beginDateVal).getTime() + 1 * 24 * 60 * 60 * 1000 - 16.64e7);}else {return time.getTime() < Date.now() - 8.64e7;}}}}},
