You just need to select the first element of the array at index 0 using:

您只需要使用以下命令在索引0处选择数组的第一个元素:

{{ mani.role[0] }}

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.name = {
    "_id": "5863d3aaacaeddc00663bc07",

    "comments": [{
      "created": 1485511936350,
      "role": [
        "user"
      ],
      "email": "selvam@e21designs.com",
      "name": "selvam R",
      "commentText": "mani selvam"
    }, {
      "created": 1485511936350,
      "role": [
        "admin"
      ],
      "email": "selvam@e21designs.com",
      "name": "selvam R",
      "commentText": "mani selvam"
    }, {
      "created": 1485511936350,
      "role": [
        "kp"
      ],
      "email": "selvam@e21designs.com",
      "name": "selvam R",
      "commentText": "mani selvam"
    }],
    "created": "2016-12-28T15:00:58.777Z",
    "isCurrentUserOwner": false
  };
});

  <div ng-repeat="mani in name.comments ">

    <td>{{$index + 1}}</td>
    <td>{{ mani.role[0] }}</td>

  </div>

You can use the toString() method to convert the array that is being displayed to a string. Like so:

您可以使用toString()方法将正在显示的数组转换为字符串。像这样:

        <td>{{mani.role.toString()}}</td>

That will display it as a string so the " and [] will be removed.

这会将其显示为字符串,以便删除“和[]。

Plunkr显示了这一点。

Your mani.role is an array, so do something like this:

你的mani.role是一个数组,所以做这样的事情:

<td><span ng-repeat="r in mani.role">{{ r }} </span></td>

#4

Your data looks like Json data, so what you need is to read Json data through AngularJS by creating module like this:

您的数据看起来像Json数据,因此您需要通过创建如下模块来通过AngularJS读取Json数据:

var App = angular.module('App', []);

App.controller('Ctrl', function($scope, $http) {
  $http.get('data.json')
       .then(function(res){
          $scope.data = res.data;                
        });
});
