AngularJS ng-options 指令
定义和用法
ng-options 指令用 <options> 填充 lt;select> 元素。
ng-options 指令使用数组来填充下拉列表。在许多情况下，使用 ng-repeat 指令会更容易，但使用 ng-options 指令时您有更大的灵活性。
实例
通过使用数组中的项目在下拉列表中填充选项：
<div ng-app="myApp" ng-controller="myCtrl">
<select ng-model="selectedName" ng-options="item for item in names"></select>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {}}
$scope.names = ["Emil", "Tobias", "Linus"];
});
</script>
Sözdizimi
<select ng-options="array expression"></select>
tarafından <select> Desteği olan elementler.
