模仿C#中的String.Format功能

<script type="text/javascript">
            var str ;
            String.prototype.template = function()
            {
                var args = arguments;                
                return this.replace(/\{(\d+)\}/g,function(m,i)
                                                    {
                                                        return args[i];
                                                    }
                                     );
            };
            
            var a = "I Love {0}, and You Love {1},Where are {0}!";
            alert(a.template("You","Me"));
            
        </script>
