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
{{dateFormat(date)}}
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
