Angularjs：ng-options

Question

考虑这个例子。我有一个画廊列表，每个画廊都选择了一个独特的客户。我也可以更改特定图库的客户端。为此，我在选择/选项列表中创建了一个客户列表。

<select ng-model="clientList" ng-options="client.id as client.clientName for client in clients" >
     <option value="">Choose Client</option>
</select>

列表从DB填充。通常我使用client.id来选择项目。作为Angularjs的新手，似乎它将自己的值分配给value =“”。在我的示例中，gallery表有一个客户端列，列出了与客户端表和client.id相关的唯一clientID。如何选择正确的客户端？

控制器

function imageGalleryCtrl ($scope, images, clients, galleries)
{

    $scope.panes = [
        { title:"Home", content:"/beta/application/views/images/uploader/create.html", active: true },
        { title:"Upload", content:"/beta/application/views/images/uploader/upload.html"},
        { title:"Edit", content:"/beta/application/views/images/uploader/edit.html"}
    ];

    //close modal
    $scope.close = function () {
        $scope.imageUploader = false;
    };

    //get gallery info on click from table
    $scope.getGallery = function(id, gallery)
    {
        //set gallery ID to scope
        $scope.galleryID = id;

        //open the modal
        $scope.imageUploader = true;

        //get gallery information
        $scope.galleryCollection = galleries.getGallery(id);

        $scope.galleryCollection.then(function(galleries){
            $scope.gallery = galleries.thisGal;
        });

        //get clients
        $scope.clientCollection = clients.getClients();

        $scope.clientCollection.then(function(clients){
            $scope.clients = clients.clients;
            //Set client
        });

        //get all the images 
        $scope.imgCollection = images.getImages(id);

        $scope.imgCollection.then(function(images){
            $scope.images = images.thisGal_images;
        });
    };
}

服务

myApp.factory('galleries', function ($http, $q)
{
    return {
        getGallery: function (id)
        {
            var deferred = $q.defer(id);

            $http.post('/beta/images/get/', {id: id}).success(function(data)
            {
                deferred.resolve(data);
            });

            return deferred.promise;
        }
    };
});

客户端服务几乎相同，仅引用正确的URL

它是模型驱动的，您需要将$ scope.clientList设置为客户端ID。在你的控制器中你可以做这样的事情

function Ctrl($scope) {
    $scope.clients = [{
        id: 1,
        clientName: 'Joe'
    }, {
        id: 2,
        clientName: 'Tom'
    }, {
        id: 3,
        clientName: 'Bob'
    }];

    $scope.clientList = 2; //clientList is the model defined in the select directive
}

的 Demo on jsFiddle

如果id字段是字符串，则应将clientList设置为字符串而不是整数：

$scope.clientList = "245";
