方法中定義：

dateFormat(time) {
                //將13位時間戳轉(zhuǎn)換成時間格式  輸出為2018-10-09
                let date = new Date(time);
                let year = date.getFullYear();
                let month = date.getMonth() + 1;
                let day = date.getDate();
                month = month < 10 ? "0" + month : month;
                day = day < 10 ? "0" + day : day;
                var myDate = ''
                myDate = year + '-' + month + '-' + day;
                return myDate
            },

方法調(diào)用

        console.log(this.dateFormat(1539083829787))  //調(diào)用傳參為數(shù)字類型   輸出為2018-10-09
