所有date中所有的tostring的方法.

console.log('orderdate:', this.OrderDate);
        console.log('toISOString:', this.OrderDate.toISOString());
        console.log('toDateString:', this.OrderDate.toDateString());
        console.log('toUTCString:', this.OrderDate.toUTCString());
        console.log('toJSON:', this.OrderDate.toJSON());
        console.log('toLocaleDateString:', this.OrderDate.toLocaleDateString());
        console.log('toLocaleString:', this.OrderDate.toLocaleString());
        console.log('toLocaleTimeString:', this.OrderDate.toLocaleTimeString());
        console.log('toString:', this.OrderDate.toString());
        console.log('toTimeString:', this.OrderDate.toTimeString());

        //  輸出結果:
        //  toISOString: 2017-12-07T16:33:01.843Z
        //  toDateString: Fri Dec 08 2017
        //  toUTCString: Thu, 07 Dec 2017 16:33:01 GMT
        //  toJSON: 2017-12-07T16:33:01.843Z
        //  toLocaleDateString: 2017/12/8
        //  toLocaleString: 2017/12/8 上午12:33:01
        //  toLocaleTimeString: 上午12:33:01
        //  toString: Fri Dec 08 2017 00:33:01 GMT+0800 (中國標准時間)
        //  toTimeString: 00:33:01 GMT+0800 (中國標准時間)
