vue处理时间戳的方法

Date.prototype.format = function(format) {
    var date = {
        "M+": this.getMonth() + 1,
        "d+": this.getDate(),
        "h+": this.getHours(),
        "m+": this.getMinutes(),
        "s+": this.getSeconds(),
        "q+": Math.floor((this.getMonth() + 3) / 3),
        "S+": this.getMilliseconds()
    };
    if (/(y+)/i.test(format)) {
          format = format.replace(RegExp.$1, (this.getFullYear() + '').substr(4 - RegExp.$1.length));
    }
    for (var k in date) {
          if (new RegExp("(" + k + ")").test(format)) {
                 format = format.replace(RegExp.$1, RegExp.$1.length == 1
                        ? date[k] : ("00" + date[k]).substr(("" + date[k]).length));
          }
    }
    return format;
}
Vue.filter('time', function (value) {
    let newDate = new Date(parseInt(value) * 1000);
    return newDate.format('yyyy-MM-dd h:m:s');
})
Vue.filter('timeDate', function (value) {
    let newDate = new Date(parseInt(value) * 1000);
