See ngOptions ngOptions(optional) – {comprehension_expression=} – in one of the following forms: For array data sources: label for value in array select as label for value in array label group by group for value in array select as label group by group for value in array track by trackexpr For object data sources: label for (key , value) in object select as label for (key , value) in object label group by group for (key, value) in object select as label group by group for (key, value) in object

对你来说，应该是

array = [{ "value": 1, "text": "1st" }, { "value": 2, "text": "2nd" }];

<select ng-options="obj.value as obj.text for obj in array"></select>

更新

随着AngularJS的更新，现在可以用track by表达式为select element的value属性设置实际值了。

<select ng-options="obj.text for obj in array track by obj.value">
</select>

如何记住这些丑陋的东西

对于那些很难记住这种语法形式的人:我同意这不是最简单或最漂亮的语法。这种语法是Python列表推导式的扩展版本，知道这一点有助于我很容易地记住语法。大概是这样的:

Python代码:

my_list = [x**2 for x in [1, 2, 3, 4, 5]]
> [1, 4, 9, 16, 25]

# Let people to be a list of person instances
my_list2 = [person.name for person in people]
> my_list2 = ['Alice', 'Bob']

这实际上与上面列出的第一个语法相同。但是，在<select>中，我们通常需要区分代码中的实际值和<select>元素中显示的文本(标签)。

比如，我们需要人手。Id，但我们不想把Id显示给用户;我们想要显示它的名字。同样，我们对代码中的person.name不感兴趣。这里有as关键字来标记东西。所以它变成了这样:

person.id as person.name for person in people

或者，代替person。Id我们可能需要person实例/引用本身。见下文:

person as person.name for person in people

对于JavaScript对象，同样的方法也适用。只需要记住，对象中的项是用(key, value)对解构的。

你可以这样做:

<select ng-model="model">
    <option value="">Select</option>
    <option ng-repeat="obj in array" value="{{obj.id}}">{{obj.name}}</option>
</select>

- - -更新

经过一些更新后，用户frm。Adiputra的解决方案要好得多。代码:

obj = { '1': '1st', '2': '2nd' };
<select ng-options="k as v for (k,v) in obj"></select>

运行代码片段并查看变化。为了快速理解，这里有一个注释

例1(对象选择):- ng-option="os.name for os in osList track by os.id"。这里由os跟踪。Id是重要的&应该在那里和os。id不应该出现在os.name之前。 ng-model="my_os"应该设置为一个key为id的对象，例如my_os={id: 2}。 例2(取值选择):- ng-option="os. "id作为osList中os的os.name”。这里由os跟踪。id不应该在那里，os。Id应该在os.name之前。 ng-model="my_os"应该设置为my_os= 2这样的值

其余代码片段将进行解释。

angular.module('app', []).controller('ctrl', function($scope, $timeout){ //************ EXAMPLE 1 ******************* $scope.osList =[ { id: 1, name :'iOS'}, { id: 2, name :'Android'}, { id: 3, name :'Windows'} ] $scope.my_os = {id: 2}; //************ EXAMPLE 2 ******************* $timeout(function(){ $scope.siteList = [ { id: 1, name: 'Google'}, { id: 2, name: 'Yahoo'}, { id: 3, name: 'Bing'} ]; }, 1000); $scope.my_site = 2; $timeout(function(){ $scope.my_site = 3; }, 2000); }) fieldset{ margin-bottom: 40px; } strong{ color:red; } <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.10/angular.min.js"></script> <div ng-app="app" ng-controller="ctrl"> <!--//************ EXAMPLE 1 *******************--> <fieldset> <legend>Example 1 (Set selection as <strong>object</strong>)</legend> <select ng-model="my_os" ng-options="os.name for os in osList track by os.id"> <option value="">--Select--</option> </select> {{my_os}} </fieldset> <!--//************ EXAMPLE 2 *******************--> <fieldset> <legend>Example 2 (Set selection as <strong>value</strong>. Simulate ajax)</legend> <select ng-model="my_site" ng-options="site.id as site.name for site in siteList"> <option value="">--Select--</option> </select> {{my_site}} </fieldset> </div>

根据我的说法，这是最适合所有场景的:

<select ng-model="mySelection.value">
   <option ng-repeat="r in myList" value="{{r.Id}}" ng-selected="mySelection.value == r.Id">{{r.Name}}
   </option>
</select>

您可以使用您的模型来绑定数据。您将获得对象将包含的值以及基于您的场景的默认选择。

用一个普通的表单提交发送一个名为my_hero的自定义值给服务器:

JSON:

"heroes": [
  {"id":"iron", "label":"Iron Man Rocks!"},
  {"id":"super", "label":"Superman Rocks!"}
]

HTML:

<select ng-model="hero" ng-options="obj.id as obj.label for obj in heroes"></select>
<input type="hidden" name="my_hero" value="{{hero}}" />

服务器将接收my_hero的值为iron或super。

这类似于@neemzy的回答，但是为value属性指定了单独的数据。

在ng-options中选择一个项目可能有点棘手，这取决于您如何设置数据源。

在与它们斗争了一段时间后，我最终用我使用的最常用的数据源制作了一个样本。你可以在这里找到它:

http://plnkr.co/edit/fGq2PM?p=preview

现在要让ng-options工作，需要考虑以下几点:

Normally you get the options from one source and the selected value from other. For example: states :: data for ng-options user.state :: Option to set as selected Based on 1, the easiest/logical thing to do is to fill the select with one source and then set the selected value trough code. Rarely would it be better to get a mixed dataset. AngularJS allows select controls to hold more than key | label. Many online examples put objects as 'key', and if you need information from the object set it that way, otherwise use the specific property you need as key. (ID, CODE, etc.. As in the plckr sample) The way to set the value of the dropdown/select control depends on #3, If the dropdown key is a single property (like in all examples in the plunkr), you just set it, e.g.: $scope.dropdownmodel = $scope.user.state; If you set the object as key, you need to loop trough the options, even assigning the object will not set the item as selected as they will have different hashkeys, e.g.: for (var i = 0, len = $scope.options.length; i < len; i++) { if ($scope.options[i].id == savedValue) { // Your own property here: console.log('Found target! '); $scope.value = $scope.options[i]; break; } }

您可以在另一个对象$scope.myObject.myProperty中替换相同属性的savedValue。
