如何在AngularJS中使用ng-repeat迭代键和值？

本文翻译自：How to iterate over the keys and values with ng-repeat in AngularJS?

In my controller, I have data like: $scope.object = data 在我的控制器中，我有以下数据： $scope.object = data

Now this data is the dictionary with keys and values from json . 现在这个数据是带有json键和值的字典。

I can access the attribute with object.name in the template. 我可以在模板中使用object.name访问该属性。 Is there any way that I can iterate over the keys as well and display them in table like 有没有什么方法可以迭代键，并在表格中显示它们

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

The data is like this 数据是这样的

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

I don't think there's a builtin function in angular for doing this, but you can do this by creating a separate scope property containing all the header names, and you can fill this property automatically like this: 我不认为有角度的内置函数可以做到这一点，但你可以通过创建一个包含所有标题名称的单独范围属性来实现，你可以像这样自动填充这个属性：

var data = {foo: 'a',bar: 'b'
};$scope.objectHeaders = [];for ( property in data ) {$scope.objectHeaders.push(property);
}// Output: [ 'foo', 'bar' ]

How about: 怎么样：

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

This method is listed in the docs: https://docs.angularjs.org/api/ng/directive/ngRepeat 此方法列在文档中： https ： //docs.angularjs.org/api/ng/directive/ngRepeat

If you would like to edit the property value with two way binding: 如果您想使用双向绑定编辑属性值：

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

Here's a working example: 这是一个有效的例子：

<div class="item item-text-wrap" ng-repeat="(key,value) in form_list"><b>{{key}}</b> : {{value}}
</div>

A todo list example which loops over object by ng-repeat : 一个todo列表示例，它通过ng-repeat循环遍历对象：

 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>
