准备
数据库中新建字段date,类型为datetime(精确到时分秒),date类型只精确到“天”
核心代码
HTML
<view >{{dateFormat(date)}}</view>
JS
data() { return { date: new Date().toISOString(), } }, mounted() { let _this = this; setInterval(function() { _this.date = Date.parse(new Date()); }, 1000); }, methods: { dateFormat(time) { let date = new Date(time); let year = date.getFullYear(); // 在日期格式中,月份是从0开始的,因此要加0,使用三元表达式在小于10的前面加0,以达到格式统一 如 09:11:05 let month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1; let day = date.getDate() < 10 ? "0" + date.getDate() : date.getDate(); let hours = date.getHours() < 10 ? "0" + date.getHours() : date.getHours(); let minutes = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes(); let seconds = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds(); // 拼接 return year + "-" + month + "-" + day + " " + hours + ":" + minutes + ":" + seconds; // return year + "-" + month + "-" + day; } }
运行结果
