将JavaScript Date对象转换成yyyy-MM-dd HH:mm:ss格式字符串的方法

if (!Date.prototype.toISOString) {
  (function() {

    function pad(number) {
      if (number < 10) {
        return '0' + number;
      }
      return number;
    }

    Date.prototype.toISOString = function() {
      return this.getUTCFullYear() +
        '-' + pad(this.getUTCMonth() + 1) +
        '-' + pad(this.getUTCDate()) +
        ' ' + pad(this.getUTCHours()) +
        ':' + pad(this.getUTCMinutes()) +
        ':' + pad(this.getUTCSeconds())
        ;
    };

  }());
}

var d = new Date()
new Date(d.getTime() - d.getTimezoneOffset() * 60000).toISOString().replace("T", " ").replace(/\..+$/,"");
//"2015-12-10 16:11:25"
