两标准日期直接算出相差几天

DateMinus(sDate){ //结束日期减去当前日期
    var sdate = new Date(sDate.replace(/-/g, "/"));
    var now = new Date();
    console.log(now)
    var days =  sdate.getTime()-now.getTime();
    var day = parseInt(days / (1000 * 60 * 60 * 24));
    if(day<=0){
        return 0
    }
    return day;
},
