在我的控制器中，我有如下数据： $scope.object = data

现在，此数据是具有来自 的键和值的字典json。

object.name我可以在模板中访问属性。有什么方法可以让我也可以遍历键并将它们显示在表格中

<tr><td> {{key}} </td> <td> data.key </td>

数据是这样的

{
    "id": 2,
    "project": "wewe2012",
    "date": "2013-02-26",
    "description": "ewew",
    "eet_no": "ewew",
}

怎么样：

<table>
  <tr ng-repeat="(key, value) in data">
    <td> {{key}} </td> <td> {{ value }} </td>
  </tr>
</table>

此方法在文档中列出：https ://docs.angularjs.org/api/ng/directive/ngRepeat

如果您想使用两种方式绑定来编辑属性值：

<tr ng-repeat="(key, value) in data">
    <td>{{key}}<input type="text" ng-model="data[key]"></td>
</tr>

我认为 Angular 中没有内置函数可以执行此操作，但是您可以通过创建一个包含所有标题名称的单独范围属性来执行此操作，并且您可以像这样自动填充此属性：

var data = {
  foo: 'a',
  bar: 'b'
};

$scope.objectHeaders = [];

for ( property in data ) {
  $scope.objectHeaders.push(property); 
}

// Output: [ 'foo', 'bar' ]

我们可以按照以下步骤来避免按字母顺序显示键值。

Javascript

$scope.data = {
   "id": 2,
   "project": "wewe2012",
   "date": "2013-02-26",
   "description": "ewew",
   "eet_no": "ewew",
};
var array = [];
for(var key in $scope.data){
    var test = {};
    test[key]=$scope.data[key];
    array.push(test);
}
$scope.data = array;

HTML

<p ng-repeat="obj in data">
   <font ng-repeat="(key, value) in obj">
      {{key}} : {{value}}
   </font>
</p>

一个todo 列表示例，它通过以下方式循环对象ng-repeat：

var app = angular.module('toDolistApp', []);
app.controller('toDoListCntrl', function() {
  var self = this;
  self.toDoListItems = {};// []; //dont use square brackets if keys are string rather than numbers.
  self.doListCounter = 0;

  self.addToDoList = function() {		  		   
    var newToDoItem = {};
    newToDoItem.title     = self.toDoEntry;
    newToDoItem.completed = false;		   

    var keyIs = "key_" + self.doListCounter++;  		   

    self.toDoListItems[keyIs] = newToDoItem;		   
    self.toDoEntry = ""; //after adding the item make the input box blank.
  };
});

app.filter('propsCounter', function() {
  return function(input) {
    return Object.keys(input).length;
  }
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="toDolistApp">    
  <div ng-controller="toDoListCntrl as toDoListCntrlAs">
    Total Items: {{toDoListCntrlAs.toDoListItems | propsCounter}}<br />
    Enter todo Item:  <input type="text" ng-model="toDoListCntrlAs.toDoEntry"/>
    <span>{{toDoListCntrlAs.toDoEntry}}</span>
    <button ng-click="toDoListCntrlAs.addToDoList()">Add Item</button> <br/>
    <div ng-repeat="(key, prop) in toDoListCntrlAs.toDoListItems"> 
      <span>{{$index+1}} : {{key}}   : Title = {{ prop.title}} : Status = {{ prop.completed}} </span>
    </div>     
  </div>    
</body>

    Use below code it is working to display your key and value here is key start with 1:
         <tr ng-repeat="(key,value) in alert_list" >
                   <td>{{key +1}}</td>
                   <td>{{value.title}}</td>
                 </tr>
Below is document link for it.

你可以在你的javascript（控制器）或你的html（角度视图）中做到这一点......

js：

$scope.arr = [];
for ( p in data ) {
  $scope.arr.push(p); 
}

html:

<tr ng-repeat="(k, v) in data">
    <td>{{k}}<input type="text" ng-model="data[k]"></td>
</tr>

我相信 html 方式更具角度，但您也可以在控制器中执行并在您的 html 中检索它...

查看对象键也不是一个坏主意，如果您需要它们，它们会为您提供键的数组，更多信息在这里：
