模拟从当天起未来两周的日期数据

模拟下面图片显示的未来14天的日期：

let nowDate = new Date();
    nowDate.setHours(0, 0, 0, 0)
    // let timestamp1 = Date.parse(nowDate)
    let timestamp = Date.parse(nowDate)
    let arr = []
    for (let i = 0; i < 14; i++){
        let obj = {}
        obj.time_stamp = timestamp
        obj.time_str = `${new Date(obj.time_stamp).getFullYear()}-${new Date(obj.time_stamp).getMonth()+1 >= 10 ? new Date(obj.time_stamp).getMonth()+1 : '0' + new Date(obj.time_stamp).getMonth()+1}-${new Date(obj.time_stamp).getDate() >= 10 ? new Date(obj.time_stamp).getDate() : '0' + new Date(obj.time_stamp).getDate()}`
        obj.time_date = `星期${'日一二三四五六'.charAt(new Date().getDay())}`
        timestamp = timestamp + 86400 * 1000
        arr.push(obj)
    }
    console.log(arr);

结果：

计算两个时间之间相差几天

 function selectDay(from, to){
        var begintime = new Date(Date.parse(from)).getTime();
        var endtime = new Date(Date.parse(to)).getTime();
        var nTime = endtime - begintime;
        var day =Math.floor(nTime/86400000);
        return day
    }
selectDay('2018-10-22', '2018-11-04')
