js 梳理树形结构

1. 更改树形结构字段属性名称

$(function() {
	treeCarding()
    function treeCarding(){
       var data = [
           {
               name: \'中国\',
               children: [
                   {
                       name: \'教第三节课\',

                   },
                   {
                       name: \'教呼呼\',
                       children: [
                           {
                               name: \'大一\',
                               children: [
                                   {
                                       name: \'课程1\',
                                       children: [
                                           {
                                               name: \'1231\'
                                           },
                                           {
                                               name: \'121\'
                                           }
                                       ]
                                   },
                                   {
                                       name: \'课程2\',
                                       children: [
                                           {
                                               name: \'1232\'
                                           },
                                           {
                                               name: \'122\'
                                           }
                                       ]
                                   },
                                   {
                                       name: \'课程3\',
                                       children: [
                                           {
                                               name: \'1233\'
                                           },
                                           {
                                               name: \'123\'
                                           }
                                       ]
                                   },

                               ]
                           }
                       ]
                   },
                   {
                       name: \'活动\',
                       children:[{
                                       name: \'aaa\'
                                   },
                                   {
                                       name: \'bbb\'
                                   }]
                   }
               ]
           }
       ];
       
    console.log(\"原始数据\",data);
    var tree=getArray(data,0);
    console.log(\"结果数据\",tree);
    function getArray(data,num){
      var trees =new Array();
      var tempTrees,fn;
      for (var i in data) {
        var newData={
          name1:data[i].name,
          childrens:[]
        }
          trees.push(newData);
          console.log(\'i\',trees);
          console.log(\'datai\',data[i].children);
          fn= getArray(data[i].children, 1);
          if (data[i].children) {
             trees[i].childrens=fn;
          } 
      }
      return trees
    }
  }
});

2.用 js 递归输出树型

 var data = [
            { id: 1,  : \'a\', pid: 0 },
            { id: 2,  : \'a1\', pid: 1 },
            { id: 3,  : \'a11\', pid: 2 },
            { id: 4,  : \'a12\', pid: 2 },
            { id: 5,  : \'a2\', pid: 1 },
            { id: 6,  : \'a21\', pid: 5 }
        ];
        function fn(data, pid) {
            var result = [], temp;
            for (var i in data) {
                if (data[i].pid == pid) {
                    result.push(data[i]);
                    temp = fn(data, data[i].id);
                    if (temp.length > 0) {
                        data[i].children = temp;
                    }
                }
            }
            return result;
        }
     console.log(fn(data, 0));


        Array.prototype.ToTreeJson = function (pid) {
            var result = [], temp;
            for (var i in this) {
                if (this[i].pid == pid) {
                    result.push(this[i]);
                    temp = fn(this, this[i].id);
                    if (temp.length > 0) {
                        this[i].children = temp;
                    }
                }
            }
            return result;
        }

        var p = data.ToTreeJson(0);
