Question

我有一个包含多个段落的新闻。我要做的是为每个段落添加一个表单控件，以便我可以单独更新它们。

这就是数据的样子

    <?php

    $con = mysqli_connect(HOST,USER,PASS,DB);

    if($_SERVER['REQUEST_METHOD']=='GET') 
    {
        $stmt = $con->prepare("SELECT user_id, category_id FROM tb_user");

             if ($stmt->execute()) {
                    $users = array();
                    $stmt->bind_result($user_id, $category_id);
                      while ($stmt->fetch()) {

                         $user["user_id"] = $user_id;
                        $user["category_id"] = $category_id;
                        $users[] = $user;
                     }

                     $stmt->close();                       

                echo json_encode($users);
            }
}

?>

我的模板看起来像这样

{
    "newsId": "42352",
    "title": "Service is now available",
    "body": [
        "Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed",
            "Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed",

    ],
    "id": 1
}

在我的组件中我现在就是这个

<div class="form-group" >
   <md-input-container class="md-block">
       <textarea mdInput type="text" rows="6" cols="" [ngModel]="news?.getBody()" class="texta" name="body" placeholder="Paragraph" #body [formControl]="updateNewsFormGroup.controls['body']"></textarea>
   </md-input-container>
</div>

如何为每个段落分别指定一个控制器？
