让JSON.js完全适应.NET

动机：.net 默认的时间序列化方式为\/Date(数字 时区)\/,序列化成JSON在前端很难处理，有没有一种好的处理方式呢？

改进：

 JSON = new function(){
     this.decode = function(){
         var    filter, result, self, tmp;
         if($$("toString")) {
             switch(arguments.length){
                 case    2:
                     self = arguments[0];
                     filter = arguments[1];
                     break;
                 case    1:
                     if($[typeof arguments[0]](arguments[0]) === Function) {
                         self = this;
                         filter = arguments[0];
                     }
                     else
                         self = arguments[0];
                     break;
                 default:
                     self = this;
                     break;
             };
             if(rc.test(self)){
                 try{
                     result = e("(".concat(self, ")"));
                     if(filter && result !== null && (tmp = $[typeof result](result)) && (tmp === Array || tmp === Object)){
                         for(self in result)
                             result[self] = v(self, result) ? filter(self, result[self]) : result[self];
                     }
                 }
                 catch(z){}
             }
             else {
                 throw new Error("bad data");
             }
         };
         return result;
     };
     this.encode = function(){
         var    self = arguments.length ? arguments[0] : this,
             result, tmp;
         if(self === null)
             result = "null";
         else if(self !== undefined && (tmp = $[typeof self](self))) {
             switch(tmp){
                 case    Array:
                     result = [];

                         if(self[j] !== undefined && (tmp = JSON.encode(self[j])))
                             result[i++] = tmp;

         };
         return result;
     };
     this.toDate = function(){

100     this.defaultDateFilter=function(k,m){ // 提供通用的时间字符串解析方式（尽可能利用原有处理机制，这一过程较消耗性能,需要解析时间时使用filter）
101     switch($[typeof m](m)){

106     }
107     return m;
108     case String:
109       return JSON.toDate(m);
110       default:
111       return m;
112     }
113     }
     var    c = {"\b":"b","\t":"t","\n":"n","\f":"f","\r":"r",'"':'"',"\\":"\\","/":"/"},
         d = function(n){return n<10?"0".concat(n):n},
         e = function(c,f,e){e=eval;delete eval;if(typeof eval==="undefined")eval=e;f=eval(""+c);eval=e;return f},

         $$ = function(m){
             function $(c,t){t=c[m];delete c[m];try{e(c)}catch(z){c[m]=t;return 1}};
             return $(Array)&&$(Object)
         };
     try{rc=new RegExp('^("(\\\\.|[^"\\\\\\n\\r])*?"|[,:{}\\[\\]0-9.\\-+Eaeflnr-u \\n\\r\\t])+?$')}
     catch(z){rc=/^(true|false|null|\[.*\]|\{.*\}|".*"|\d+|\d+\.\d+)$/}
 };

至此，已经可以轻松搞定JSON时间处理的麻烦。不过这里有一点点不完美的地方，要求.NET端的时间使用UTC时间，总的来说这也不是什么大的缺陷，可以接受。我的理由是在多时区时就应当在服务端使用UTC时间。
