json.net 遍历 jsonobject遍历键值对

JSON既然是键值对应该可以像.net里的Dictionary一样可以遍历才对。试试看：

//递归遍历JSON所有键值
    function recurJson(json) 
    { 
        for(var i in json){         
            document.write(i+":"+json[i]+" <br>");        
            if(typeof json[i]=="object"){ 
                recurJson(json[i]); 
            } 
        } 
    }  
 var    dd={"a":"=a","b":"=b","c":"=c","d":{"d1":"=d1","d2":"=d2"}};
    dd.a="=a2";
    recurJson(dd);

 输出：
a:=a2
b:=b
c:=c
d:[object Object]
d1:=d1
d2:=d2  

 var record=new Ext.data.Record({"a":"=a","b":"=b","c":"=c","d":{"d1":"=d1","d2":"=d2"}});
    //record.set("a","a=a");//修改键值
    //Ext.Msg.alert("提示", record.get("d").d1);//获取键值    
    //recurJson(record.data);//遍历Record的数据    
    recurJson(record);    //遍历Record的配置项，配置项本身就是JSON格式的

输出：
isModified:function(A){return this.modified&&this.modified.hasOwnProperty(A)}
copy:function(A){return new this.constructor(Ext.apply({},this.data),A||this.id)}
clearError:function(){this.error=null}
hasError:function(){return this.error!=null}
getChanges:function(){var A=this.modified,B={};for(var C in A){if(A.hasOwnProperty(C)){B[C]=this.data[C]}}return B}
commit:function(A){this.dirty=false;delete this.modified;this.editing=false;if(this.store&&A!==true){this.store.afterCommit(this)}}
reject:function(B){var A=this.modified;for(var C in A){if(typeof A[C]!="function"){this.data[C]=A[C]}}this.dirty=false;delete this.modified;this.editing=false;if(this.store&&B!==true){this.store.afterReject(this)}}
endEdit:function(){this.editing=false;if(this.dirty&&this.store){this.store.afterEdit(this)}}
cancelEdit:function(){this.editing=false;delete this.modified}
beginEdit:function(){this.editing=true;this.modified={}}
get:function(A){return this.data[A]}
set:function(A,B){if(String(this.data[A])==String(B)){return }this.dirty=true;if(!this.modified){this.modified={}}if(typeof this.modified[A]=="undefined"){this.modified[A]=this.data[A]}this.data[A]=B;if(!this.editing&&this.store){this.store.afterEdit(this)}}
join:function(A){this.store=A}
modified:null
error:null
editing:false
dirty:false
id:1001
data:[object Object]
a:=a
b:=b
c:=c
d:[object Object]
d1:=d1
d2:=d2
综合以上：定义一个JSON类：
