一、在方法中写入以下代码： methods: { getDay (day, hours) { var today = new Date() var targetday = today.getTime() + 1000 * 60 * 60 * 24 * day + hours today.setTime(targetday) var tYear = today.getFullYear() var tMonth = today.getMonth() var tDate = today.getDate() var getHours = today.getHours() tMonth = this.doHandleMonth(tMonth + 1) tDate = this.doHandleMonth(tDate) return tYear + '-' + tMonth + '-' + tDate + '小时：' + getHours }, doHandleMonth (month) { var m = month if (month.toString().length === 1) { m = '0' + month } return m }, } 二、测试： mounted () { console.log('昨天：', this.getDay(-1, 7200000)) console.log('今天：', this.getDay(0, 3600000)) console.log('明天：', this.getDay(1, 3600000)) console.log('一周后：', this.getDay(7, 7200000) }
效果：
