tree型的json数据按照json的某个字段对子节点进行排序

项目中要求tree型的json数据按照json的某个字段对子节点进行排序，自己花时间写了写，整理如下：

要求：按照type属性对json数据进行排序，没有子节点（type=0）的排在前面

1.初始效果图和排序后效果图





1.嵌套子节点的json数据：

var data = [{"id":1,"name":"陕西省","type":1,children:
                 [ {"id":11,"name":"延安市","type":0,"state":"open"},
                   {"id":12,"name":"西安市","type":1,children:
                     [ {"id":121,"name":"长安区","type":1,children:
                        [{"id":1211,"name":"蓝田镇","type":1,children:
                          [
                           {"id":12113,"name":"武安村","type":1,children:
                             [{"id":121131,"name":"456号","type":1},
                              {"id":121132,"name":"458号","type":0},
                              {"id":121133,"name":"477号","type":0}
                             ]
                           },
                           {"id":12111,"name":"爱丽村","type":1,"state":"closed"},
                           {"id":12112,"name":"玫瑰村","type":0}
                          ]
                         },
                         {"id":1212,"name":"西斯镇","type":0}
                        ]
                     },
                       {"id":122,"name":"雁塔区","type":0},
                       {"id":123,"name":"莲湖区","type":0}
                     ]
                   },
                   {"id":13,"name":"宝鸡市","type":0,"state":"closed"},
                   {"id":14,"name":"汉中市","type":0,"state":"closed"},
                   {"id":15,"name":"渭南市","type":1,children:
                     [ {"id":151,"name":"临渭区","type":1,children:
                         [ {"id":1511,"name":"前进路","type":0},
                           {"id":1512,"name":"东风街","type":0},
                           {"id":1513,"name":"西四路","type":0}
                         ]
                       },
                       {"id":152,"name":"大荔县","type":0},
                       {"id":153,"name":"华县","type":0}
                     ]
                   }
                 ]
               }]

2.排序函数

$(function(){
        $("#tree").tree({
          data:data,
          formatter:function(node){
            return node.name;
          },
          loadFilter:function(data){
          var len = data.length;
          for(var i = 0;i < len;i++){
            //使用匿名函数
           (function(){
            //arguments[0]指的是函数的第一个参数，此处为data[0],即陕西省这一父节点的json格式数据
           var jsonArray = arguments[0];
           for(var k in jsonArray){
           //排序的条件:①存在子节点②子节点的个数大于1
            if(k.indexOf('children')!=-1&&jsonArray[k]!=null){
              if(jsonArray[k].length>1){
                 jsonArray[k] = jsonArray[k].sort(function(a,b){
                     return a.type > b.type? 1 : -1;
                });
             }
             console.log("递归前");
             //递归的条件①有子节点②父节点的类型为1
             console.log(jsonArray);
             if(jsonArray[k].length>0&&jsonArray.type==1){
               console.log("递归");
                for(var j = 0;j<jsonArray[k].length;j++){             
                   //子节点类型如果为0，退出本次循环
                   if(jsonArray[k][j].type==0){
                       continue;
                   }
                   console.log("diguio");
                  //递归调用匿名函数
                  arguments.callee(jsonArray[k][j]);
               }
             }
          }         
      }
    })(data[i]);
         return data;
    }                  
 }
});
 });
