Question

我无法在视图中显示数据。我在results.data上看到了ajax加载的结果，但是我无法显示结果。

JSON数据是 -

[{
    "locationId": 14,
    "name": "coin"
},
{
    "locationId": 11,
    "name": "coop"
},
{
    "locationId": 5,
    "name": "dxd"
},
{
    "locationId": 15,
    "name": "dxd2"
},
{
    "locationId": 1017,
    "name": "inka"
},
{
    "locationId": 16,
    "name": "test-pinco"
},
{
    "locationId": 13,
    "name": "upimuim"
}]

查看

<div class="row">
    <div class="col-md-2">
        &nbsp;
    </div>
    <div class="col-md-8">
        <table class="table table-striped table-bordered table-hover">
            <thead>
                <tr>
                    <th>LocationId</th>
                    <th>Name</th>
                </tr>
            </thead>
            <tbody>
                <tr data-ng-repeat="order in orders">
                    <td>
                        {{ locationId }}
                    </td>
                    <td>
                        {{ name }}
                    </td>
                </tr>
            </tbody>
        </table>
    </div>
    <div class="col-md-2">
        &nbsp;
    </div>
</div>

控制器

'use strict';
app.controller('locationsController', ['$scope', 'locationsService', function ($scope, locationsService) {

    $scope.locations = [];

    locationsService.getLocations().then(function (results) {

        $scope.locations = results.data;

    }, function (error) {
        //alert(error.data.message);
    });

}]);

服务

'use strict';
app.factory('locationsService', ['$http', function ($http) {

    var serviceBase = 'http://localhost:4014/';
    var locationsServiceFactory = {};

    var _getLocations = function () {

        return $http.get(serviceBase + 'api/locations').then(function (results) {
            return results;
        });
    };

    locationsServiceFactory.getLocations = _getLocations;

    return locationsServiceFactory;

}]);

Answer 1

在视图中尝试此操作 -

将$ scope.locations替换为$ scope.orders，然后使用order.locationID和order.name。

Answer 2

您的服务应该返回承诺：

app.factory('locationsService', ['$http', function ($http) {

    var serviceBase = 'http://localhost:4014/';
    var locationsServiceFactory = {};

    var _getLocations = function () {

        // return a promise
        return $http.get(serviceBase + 'api/locations');
    };

    locationsServiceFactory.getLocations = _getLocations;

    return locationsServiceFactory;

}]);

您的观点应该在ng-repeat中引用顺序：

<tr data-ng-repeat="order in orders">
    <td>
        {{ order.locationId }}
    </td>
    <td>
        {{ order.name }}
    </td>
</tr>

Answer 3

以下内容应该有效：位置ID和名称是订单对象的属性。因此，要访问它们，我们需要以这种方式访问： order.locationId，order.Name

    <div class="row">
        <div class="col-md-2">
            &nbsp;
        </div>
        <div class="col-md-8">
            <table class="table table-striped table-bordered table-hover">
                <thead>
                    <tr>
                        <th>LocationId</th>
                        <th>Name</th>
                    </tr>
                </thead>
                <tbody>
                    <tr data-ng-repeat="order in orders">
                        <td>
                            {{ order.locationId }}
                        </td>
                        <td>
                            {{ order.name }}
                        </td>
                    </tr>
                </tbody>
            </table>
        </div>
        <div class="col-md-2">
            &nbsp;
        </div>
    </div>
