ng-repeat ng-repeat angularJS內部

Question

我正在使用AJAX在angularJS中進行項目，這是一個具有類似按鈕的發布/評論系統。 到目前為止，一切工作正常，但要讀取數據庫中的注釋，應該使用第一個讀取帖子的ng-repeat來完成。

我可以通過servicoLeituraComments.php頁面接收到數據良好的json，所有數據都在那里。 我認為問題出在ng-repeat上，但是我不確定當它在另一個內時我應該怎么做，我已經在上面嘗試過“ comments”或“ p.comments”，但均無用。 我在第二次ng-repeat中鍵入的任何內容也不會顯示在頁面上。 這是代碼。

  <script>
    var app = angular.module('postsApp', []);
    var interval;

    app.controller('postsCtrl', function($scope) {
        $scope.toggle = false;
        $scope.texto = [];
        $scope.comment = [];
        $scope.comment = "";
        $scope.comments = "";
        $scope.posts = "";
        $scope.texto = "";
        $scope.idPost = 0;
        $scope.showBox = function(p){

          p.toggle = !p.toggle;


          if(interval == 0){
            interval = setInterval("angular.element($('#postsApp')).scope().servicoLeituraPosts()",1000);
          }else{
            clearInterval(interval);
            interval = 0;

          }
           servicoLeituraComments(p);
        };
        $scope.iniciaTimer = function(){
               interval = setInterval("angular.element($('#postsApp')).scope().servicoLeituraPosts()",1000);
        };
        $scope.servicoLeituraPosts = function(){        
                $.getJSON(
                        "servicoLeituraPosts.php",
                        {

                        },
                        function(jsonData)
                        {
                            $scope.posts = jsonData;
                            $scope.$apply();
                        });
        };
        $scope.servicoLeituraComments = function(p){        
                $.getJSON(
                        "servicoLeituraComments.php",
                        {
                            "idPost": p.idPost
                        },
                        function(jsonData)
                        {
                            $scope.comments = jsonData;
                            $scope.$apply();
                        });
        };

Answer 1

所以我在這里看到兩件事。 首先是您要從中獲取注釋的JSON沒有注釋屬性。 如果這樣做，它將是這樣的：

{
        "idPost":"12",
        "data":"2017-06-21 01:17:05",
        "nome":"joao",
        "texto":"Ola",
        "idAutor":"3",
        "numeroLikes":"3"
        "comments": []  //This is missing, these would be p.comments
}

我看到的第二件事是您有一個帶有ng-model="p.comments"的<textarea> 。 您是否要使用它向$scope.posts添加注釋？ 如果是這樣，您應該將該模型更改為類似ng-model="newComment"並且addComment()應該找到$scope.newComment並將其推送到$scope.posts

嘗試這個：

ng-click="addComment($index)"

$scope.addComment = function(index){
  $scope.posts[index].comments.push($scope.newComment);
  $scope.newComment = '';
}

編輯

是否以一種JSON形式獲取帖子，以另一種形式獲取評論都無關緊要。 我能看到的唯一問題是注釋JSON的方式。 評論將需要有另一個字段，以了解要附加到哪些帖子。 像這樣：

{
    "nome":"joao",
    "texto":"12345",
    "data":null,
    "idPost": "12"  //This is how you would know that this comment goes to this post
}

Answer 2

謝謝大家，我設法解決了這個問題，我將兩個ng-repeats分別放在另一個內部，因為我有2個JSON，它們的數據通過ID相互關聯。
