如何使用AngularJS获取选项文本值?

I'm trying to get a text value of an option list using AngularJS

我正在尝试使用AngularJS获取选项列表的文本值

Here is my code snippet

这是我的代码片段

<div class="container-fluid">
        Sort by:
        <select ng-model="productList">
            <option value="prod_1">Product 1</option>
            <option value="prod_2">Product 2</option>
        </select>
</div>

<p>Ordered by: {{productList}}</p>

{{productList}} returns the value of the option, eg: prod_1. I'm trying to get the text value 'Product 1'. Is there a way to do this?

{{productList}}返回选项的值，例如:prod_1。我想要得到文本值Product 1。有办法吗?

The best way is to use the ng-options directive on the select element.

最好的方法是在select元素上使用ng-options指令。

Controller

控制器

function Ctrl($scope) {
  // sort options
  $scope.products = [{
    value: 'prod_1',
    label: 'Product 1'
  }, {
    value: 'prod_2',
    label: 'Product 2'
  }];   
}

HTML

HTML

<select ng-model="selected_product" 
        ng-options="product as product.label for product in products">           
</select>

This will bind the selected product object to the ng-model property - selected_product. After that you can use this:

这将把选中的product对象绑定到ng-model属性selected_product。之后你可以使用这个:

<p>Ordered by: {{selected_product.label}}</p>

Instead of ng-options="product as product.label for product in products"> in the select element, you can even use this:

而不是ng-options=“product as product”。产品标签在“>在选择元素中，你甚至可以使用这个:

<option ng-repeat="product in products" value="{{product.label}}">{{product.label}}

which works just fine as well.

这也很有效。

Also you can do like this:

你也可以这样做:

<select class="form-control postType" ng-model="selectedProd">
    <option ng-repeat="product in productList" value="{{product}}">{{product.name}}</option>
</select>

where "selectedProd" will be selected product.

选择“selectedProd”的产品。

<div ng-controller="ExampleController">
  <form name="myForm">
    <label for="repeatSelect"> Repeat select: </label>
    <select name="repeatSelect" id="repeatSelect" ng-model="data.model">
      <option ng-repeat="option in data.availableOptions" value="{{option.id}}">{{option.name}}</option>
    </select>
  </form>
  <hr>
  <tt>model = {{data.model}}</tt><br/>
</div>

AngularJS:

angular.module('ngrepeatSelect', [])
 .controller('ExampleController', ['$scope', function($scope) {
   $scope.data = {
    model: null,
    availableOptions: [
      {id: '1', name: 'Option A'},
      {id: '2', name: 'Option B'},
      {id: '3', name: 'Option C'}
    ]
   };
}]);
