AngularJS Select(选择框)

使用 ng-options 创建选择框

<div ng-app="myApp" ng-controller="myCtrl">

<select ng-model="selectedName" ng-options="x for x in names">

</select>

</div>

<script>

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

app.controller('myCtrl', function($scope) {

    $scope.names = ["Google", "Runoob", "Taobao"];

});

</script>

<p>该实例演示了 ng-options 指令的使用。</p>

ng-options 选择的是对象操作灵活与 ng-repeat选择的是字符串

<div ng-app="myApp" ng-controller="myCtrl">

<select>

<option ng-repeat="x in names">{{x}}</option>

</select>

</div>

<script>

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

app.controller('myCtrl', function($scope) {

    $scope.names = ["Google", "Runoob", "Taobao"];

});

</script>

<p>该实例演示了使用 ng-repeat 指令来创建下拉列表。</p>

<div ng-app="myApp" ng-controller="myCtrl">

<p>选择网站:</p>

<select ng-model="selectedSite" ng-options="x.site for x in sites">

</select>

<h1>你选择的是: {{selectedSite.site}}</h1>

<p>网址为: {{selectedSite.url}}</p>

</div>

<script>

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

app.controller('myCtrl', function($scope) {

   $scope.sites = [

   {site : "Google", url : "http://www.google.com"},

   {site : "Runoob", url : "http://www.runoob.com"},

   {site : "Taobao", url : "http://www.taobao.com"}

];

});

</script>

<p>该实例演示了使用 ng-option指令来创建下拉列表，选中的值是一个字符串。</p>

数据源为对象

 使用对象作为数据源, x 为键(key), y 为值(value):

你选择的值为在 key-value 对中的 value。

value 在 key-value 对中也可以是个对象：

 div ng-app="myApp" ng-controller="myCtrl">

<p>选择一辆车:</p>

<select ng-model="selectedCar" ng-options="x for (x, y) in cars">
</select>

<h1>你选择的是: {{selectedCar.brand}}</h1>
<h2>模型: {{selectedCar.model}}</h2>
<h3>颜色: {{selectedCar.color}}</h3>

<p>注意选中的值是一个对象。</p>
</div>

<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.cars = {
        car01 : {brand : "Ford", model : "Mustang", color : "red"},
        car02 : {brand : "Fiat", model : "500", color : "white"},
        car03 : {brand : "Volvo", model : "XC90", color : "black"}
    }
});
</script>

<div ng-app="myApp" ng-controller="myCtrl">

<p>选择一辆车:</p>

<select ng-model="selectedCar" ng-options="y.brand for (x, y) in cars">
</select>

<h1>你选择的是: {{selectedCar.brand}}</h1>
<h2>模型: {{selectedCar.model}}</h2>
<h3>颜色: {{selectedCar.color}}</h3>

<p>下拉列表中的选项也可以是对象的属性。</p>

</div>

<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.cars = {
        car01 : {brand : "Ford", model : "Mustang", color : "red"},
        car02 : {brand : "Fiat", model : "500", color : "white"},
        car03 : {brand : "Volvo", model : "XC90", color : "black"}
    }
});
