ng-repeat中的AngularJS ng-option
Lia*_*nat 11 javascript angularjs
很简单的问题,但不知道如何解决它
我有重复,重复模型视频.
模型有一个选定的值,我想在下拉列表中看到它:
<div data-ng-repeat="singleVideo in model.videos">
{{singleVideo}}<select data-ng-model="singleVideo.name" ng-options="item.name for item in videoList"></select>
</div>
这是视频模型:
$scope.model = {
videos:[
{id:1,name:"VIDEO_ONE"},
{id:2,name:"VIDEO_TWO"}
]
}
这是videoList项:
$scope.videoList = [
{id:1,name:"VIDEO_ONE"},
{id:2,name:"VIDEO_TWO"},
{id:3,name:"VIDEO_Three"}
];
我只希望看到第一个下拉值设置为VIDEO_ONE,第二个下拉值将设置为VIDEO_TWO.
目前下拉列表是空的.
我怎样才能做到这一点？
您只需要为ng-options设置一个值item.id as item.name for item in videoList.见下面的代码.
(我将id设置为值,因为我觉得它更适合.在某个地方你还需要name根据id.或者ver verca 来更新你的属性.你的选择.)
angular.module('testapp', [])
.controller('appCtrl', function($scope) {
$scope.model = {
videos:[
{id:1,name:"VIDEO_ONE"},
{id:2,name:"VIDEO_TWO"}
]
};
$scope.videoList = [
{id:1,name:"VIDEO_ONE"},
{id:2,name:"VIDEO_TWO"},
{id:3,name:"VIDEO_Three"}
];
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="testapp">
<div ng-controller="appCtrl">
<div ng-repeat="singleVideo in model.videos">
{{singleVideo.name}}
<select ng-model="singleVideo.id" ng-options="item.id as item.name for item in videoList" ng-selected="true"></select>
</div>
</div>
</body>| 归档时间： |
