data (){
   return {
       pickerOptions: {
          disabledDate(time) {
            return time.getTime() < Date.now() - 8.64e7;
          }
        },  
   }     
} 

情景2: 设置选择今天以及今天以前的日期

data (){
   return {
       pickerOptions: {
          disabledDate(time) {
            return time.getTime() > Date.now() - 8.64e6;
          }
        },  
   }     
}   

情景3: 设置选择三个月之内到今天的日期

data (){
   return {
       pickerOptions: {
          disabledDate(time) {
           	let curDate = (new Date()).getTime();
           	let three = 90 * 24 * 3600 * 1000;
          	let threeMonths = curDate - three;
            return time.getTime() > Date.now() || time.getTime() < threeMonths;
          }
        },  
   }     
}   

情景4: 设置选择最大范围为30天

data (){
   return {
   	   pickerMinDate: null,
       pickerMaxDate: null,
       pickerOptions: {
	     onPick: ({ maxDate, minDate }) => {
	         if (minDate && this.pickerMinDate) {
	           this.pickerMinDate = null;
	         } else if (minDate) {
	           this.pickerMinDate = minDate.getTime();
	         }
	      },
          disabledDate: (time) => {
          	if (this.pickerMinDate) {
            	const day1 =  30 * 24 * 3600 * 1000
           		let maxTime = this.pickerMinDate + day1
            	let minTime = this.pickerMinDate - day1
            	return time.getTime() > maxTime || time.getTime()<minTime || time.getTime() > Date.now()
          	} else {
            	return time.getTime() > Date.now()
          	}
       	  },
