vue:過濾器---時間戳格式轉化

//新建js文件
export function formatDate (date, fmt) {
    if (/(y+)/.test(fmt)) {
        fmt = fmt.replace(RegExp.$1, 
                (date.getFullYear() + '').substr(4 - RegExp.$1.length));
    }
    let o = {
        'M+': date.getMonth() + 1,
        'd+': date.getDate(),
        'h+': date.getHours(),
        'm+': date.getMinutes(),
        's+': date.getSeconds()
    };
    for (let k in o) {
        if (new RegExp(`(${k})`).test(fmt)) {
            let str = o[k] + '';
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length === 1) ? 
            str : padLeftZero(str));
        }
    }
    return fmt;
};
 
function padLeftZero (str) {
    return ('00' + str).substr(str.length);
};

添加過濾器：

filters: {
    formatDate(time) {
      var date = new Date(time);
      return formatDate(date, "yyyy-MM-dd");
    }
  }

 

 

二、

filters: {
      formatDate: function (value) {
        let date = new Date(value);
        let y = date.getFullYear();
        let MM = date.getMonth() + 1;
        MM = MM < 10 ? ('0' + MM) : MM;
        let d = date.getDate();
        d = d < 10 ? ('0' + d) : d;
        let h = date.getHours();
        h = h < 10 ? ('0' + h) : h;
        let m = date.getMinutes();
        m = m < 10 ? ('0' + m) : m;
        let s = date.getSeconds();
        s = s < 10 ? ('0' + s) : s;
        return y + '-' + MM + '-' + d + ' ' + h + ':' + m + ':' + s;
      }
