java - AngularJS到Spring Controller

我对angularjs很陌生。现在我的一个视图中有一个复选框

<input id="{{fields[3].name}}" type="checkbox" value="{{fields[3].name}}" ng-checked="selection.indexOf(fields[3].name) > -1" ng-click="toggleSelection(fields[3].name)" class="col-xs-1" />

在弹簧控制器（如下所示）中，如何检查复选框是否已选中？

@RequestMapping(value = "/test/{id}/accept", method = RequestMethod.POST, produces = "application/json", consumes = "application/json")
        public @ResponseBody ResponseBean acceptData(
                @PathVariable("id") String id,
                @RequestBody AcceptPayload payload, Model model,
                HttpServletRequest request, HttpServletResponse response) {
....
    }

任何代码示例都将有所帮助

最佳答案

您需要将检查的数据从您的网页发送到控制器。

该网页将具有ng-repeat，如下所示。变量列表包含json数组：

<tr ng-repeat="obj in list">
    <td>
           <input id="{{obj.name}}" type="checkbox" value="{{obj.name}}"
           checklist-model="checkboxes" ng-checked="selection.indexOf(obj.name) > -1"
           ng-click="toggleSelection(obj.name)" />
   </td>
</tr>

toggleSelection（）函数将获取所选obj.name的数组，并将其添加到变量数组** selectedItems **中：

$scope.selectedItems = [];
$scope.toggleSelection = function toggleSelection(name) {
    var idx = $scope.selectedItems.indexOf(name);
    // is currently selected
    if (idx > -1) {
        $scope.selectedItems.splice(idx, 1);
    }
    // is newly selected
    else {
        $scope.selectedItems.push(name);
    }
};

我在网页中点击控制器的方式如下：

$scope.execute = function() {
    $http({
        method : 'GET',
        url : 'trigger',
        params : {
                     selectedItems : $scope.selectedItems
                }
        }).success(
            function(data, status, headers, config) {
        }).error(
            function(data, status, headers, config) {
            // called asynchronously if an error occurs
            // or server returns response with an error status.
    });
                        };

控制器中的方法如下所示：

@RequestMapping(value = "/trigger", method = RequestMethod.GET, headers = "Accept=application/json")
public @ResponseBody String trigger(@RequestParam("selectedItems") List<String> selectedItems) throws NumberFormatException, Exception {
        // Your method
    }

您可以根据需要将方法从GET更改为POST。
