主要的更改是解决了 日期能到 31/32 的问题，实现了到月底自动切换到下一月的1号

这里博主自己封了一个新的函数 主要用到了 setDate（）这个 时间函数

        //获取几天后日期
     dateCount(arg, date) {
        var date1 = arg;
        var date2 = new Date(date1);
        date2.setDate(date2.getDate() + parseInt(date));
        var times = date2.getFullYear() + "-" + (date2.getMonth() + 1) + "-" + date2.getDate();
        var Year = 0;
        var Month = 0;
        var Day = 0;
        var CurrentDate = "";
        Year = date2.getFullYear();
        Month = date2.getMonth() + 1;
        Day = date2.getDate();
        CurrentDate += Year + "-";
        if (Month >= 10) {
            CurrentDate += Month + "-";
        } else {
            CurrentDate += "0" + Month + "-";
        }
        if (Day >= 10) {
            CurrentDate += Day;
        } else {
            CurrentDate += "0" + Day;
        }
        return CurrentDate;
    },

这是整个项目页面的代码：
