このコードを持っています:
PostApp.factory('loadPage', function ($http) {
return {
loadOtherPage: function (page, status, permition, order, cultureId) {
$http({
url: '/Administrator/Post/PagedIndex',
method: "POST",
data: { page: page, status: status, permition: permition, order: order, cultureId: cultureId }
}).success(function(data) {
return data;
});
}
};
.
});
PostApp.controller('PostController',
function ($scope, $http, loadPage) {
$scope.status = 'Published';
$scope.permition = 'Global';
$scope.order = 'Asscending';
$scope.cultureId = 1;
$scope.ListOfItems = [];
$scope.start = 2;
$scope.skip = 10;
$scope.loaddata = function () {
$scope.ListOfItems = loadPage.loadOtherPage($scope.start, $scope.status, $scope.permition, $scope.order, $scope.cultureId);
};
}
.
);
しかし、$ scope.ltofitems aniboutibleに$ scope.listofitemを$ scope.ltofitemsに応答してはいけません。 レスポンスはブラウザのコンソールのJSON:
[{"PId":15,"Id":15,"Status":"انتشار","Permition":"سراسری","PublishedDateEn":"08/19/2013","Title":"xxxxxxxxxxxx","CultureId":1,"Username":"naser","CommentCount":0},{"PId":16,"Id":16,"Status":"انتشار","Permition":"سراسری","PublishedDateEn":"08/19/2013","Title":"yyyyyyyyyyyyyyyyyy","CultureId":1,"Username":"naser","CommentCount":0},{"PId":17,"Id":17,"Status":"انتشار","Permition":"سراسری","PublishedDateEn":"08/21/2013","Title":"zzzzzzzzzzzzzzzz","CultureId":1,"Username":"naser","CommentCount":0}]
.
Final $ Scope.ListOfitemは空ですか?
解決
(編集:追加の明確さのための変数の追加)
loadOtherPage
関数は何も返さず、それが$scope.ListOfItems
が空の理由です。それをするための適切な方法は次のようなものです:
loadOtherPage: function (page, status, permition, order, cultureId) {
var httpPromise = $http({
url: '/Administrator/Post/PagedIndex',
method: "POST",
data: { ... }
});
return httpPromise;
}
.
$http
が呼び出し元に戻るという約束を本質的に返します。あなたのコントローラーは次のようになるべきです:
$scope.loaddata = function () {
var loadPagePromise = loadPage.loadOtherPage( ... );
loadPagePromise.success(function(data) {
$scope.ListOfItems = data;
});
};
