一：javascript中實現分隔顯示字串

keyup(function () {                this.value = this.value.replace(/[^\w{8}\d{8}]/g, "").replace(/(\w{4})(?=\w)/g, "$1 ");            });

效果：

 

二：C#中實現分隔字串

  static void Main(string[] args)        {                        //int count = 13;            //int spt = 4;            //var xx = Math.Ceiling((double)count / spt);            //Console.Write(xx);            string str = "KEI4DXER345";            int spt = 4;            var xx = Math.Ceiling((double)str.Length/spt);            string result = string.Empty;            for (int i = 0; i < xx-1; i++)            {                result += str.Substring((i * 4), 4) + " ";            }            result += str.Substring(((int)(xx-1) * 4));            Console.Write("result:   [{0}]  ",result);
