显示JSON与角

嵌套的树我有这个JSON，我需要证明的这三个节点树角JS：data.key & data.parentItem & data.title。显示JSON与角

这是我的js代码：

var phonecatApp = angular.module('myApp', []) 
 
phonecatApp.controller('myController', function myController($scope, $http) { 
 
    $http.get('https://api.zotero.org/users/475425/collections/9KH9TNSJ/items?format=json') 
 
    .then(function (response) { 
 
     var data = response.data 
 

 
     data = data.filter(function (obj) { 
 
      return true 
 
     }) 
 
     .map(function (obj) { 
 
      return { 
 
      key: obj.key, 
 
      parentItem: obj.data.parentItem, 
 
      title: obj.data.title 
 
      } 
 
     }) 
 

 
     var log = [] 
 
     var parent = angular.forEach(data, function (value, key) { 
 
     if (value.parentItem === undefined) { 
 
      this.push(value) 
 
     } 
 
     }, log) 
 
     $scope.paR = log 
 

 
     var nlog = [] 
 
     var children = angular.forEach(data, function (value, key) { 
 
     if (value.parentItem !== undefined) { 
 
      this.push(value) 
 
     } 
 
     }, nlog) 
 
     $scope.chilD = nlog 
 
    }) 
 
})

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> 
 
<!DOCTYPE html> 
 
<html ng-app="myApp">

     <h3>{{myJ.key}}</h3></li> 
 
     <li>{{myJ.title}}</li> 
 
    </ul> 
 
    <ul ng-repeat="myN in chilD"> 
 
     <li> 
 
      <h3 style="color:red">{{myN.key}}</h3></li> 
 
     <li>{{myN.title}}</li> 
 
     </ul> 
 
    </div>

我的一些JSON项目都是家长和一些主题是孩子。如何做到尊重父母和孩子的规则，并在与nLogn的树中展示主题？

的可能的复制[角JS像格式树呈现JSON（http://stackoverflow.com/questions/22168343/angular-js-render-json-in-tree-像格式） –

我不明白“关于父母和孩子的规则”你的'数据'对象只有一个子节点，你能否详细说明？ –

也做一个'角度递归指令'或'角度递归模板'的网络搜索。应该找到大量的例子和教程 – charlietfl

这就是答案！

var phonecatApp = angular.module('myApp', []) 
 
phonecatApp.controller('myController', function myController($scope, $http) { 
 
    $http.get('https://api.zotero.org/users/475425/collections/9KH9TNSJ/items?format=json') 
 
    .then(function(response) { 
 
     var data = response.data 
 

 
     data = data.filter(function(obj) { 
 
      return true 
 
     }) 
 
     .map(function(obj) { 
 
      return { 
 
      key: obj.key, 
 
      parentItem: obj.data.parentItem, 
 
      title: obj.data.title 
 
      } 
 
     }) 
 
     console.log(data) 
 

 
     $scope.getParentData = function() { 
 
     var log = [] 
 

 
     angular.forEach(data, function(value, key) { 
 
      if (value.parentItem === undefined) { 
 
      this.push(value) 
 
      } 
 
     }, log) 
 
     return log 
 
     console.log(log) 
 
     } 
 

 
     $scope.getChilds = function(p) { 
 
     var log = [] 
 

 
     angular.forEach(data, function(value, key) { 
 
      if (!value.parentItem || value.parentItem !== p.key) { 
 
      return 
 
      } 
 
      this.push(value) 
 
     }, log) 
 
     return log 
 
     console.log(log) 
 
     } 
 
    }) 
 
})

你可以使用这个伟大的指令：角树视图

http://ngmodules.org/modules/angular.treeview

它需要一个JSON这样

$scope.treedata = 
[ 
    { "label" : "User", "id" : "role1", "children" : [ 
     { "label" : "subUser1", "id" : "role11", "children" : [] }, 
     { "label" : "subUser2", "id" : "role12", "children" : [ 
      { "label" : "subUser2-1", "id" : "role121", "children" : [ 
       { "label" : "subUser2-1-1", "id" : "role1211", "children" : [] }, 
       { "label" : "subUser2-1-2", "id" : "role1212", "children" : [] } 
      ]} 
     ]} 
    ]}, 
    { "label" : "Admin", "id" : "role2", "children" : [] }, 
    { "label" : "Guest", "id" : "role3", "children" : [] } 
];

，并显示它

你需要一点格式化您的数据可能是
