Question

我正在与大学项目合作。我有REST API和弹簧启动以及angularJs前端。这是我对angularJs的工作部分。

HomeService.js

this.getDeviceList = function getDeviceList(){
    return $http.get(REST_SERVICE_URI + '/get_device_list')

}

 this.getPeripheralList = function getPeripheralList(dev_hard_id){
    return $http.get(REST_SERVICE_URI + '/get_peripherals/?dev_hard_id=' + dev_hard_id)
}

HomeController.js中的工作函数

$scope.getDeviceList = function () {
    HomeService.getDeviceList()
      .then (function success(response){ 
          $scope.details = response.data;
          $scope.errorMessage = '';
      },

      function error(response){
          $scope.errorMessage = 'Error occured!!!';
          $scope.message = response.data.message;
    });
}

$scope.getPeripheralList = function (devHardwareId){
    HomeService.getPeripheralList(devHardwareId)
    .then (function success(response){
        $scope.peripheralDetails = response.data;
        $scope.errorMessage = '';
    },
    function error(response) {
        $scope.errorMessage = 'Error occured!!!';
        $scope.message = response.data.message;

    });
}

html文件中的工作原语表。

<div class="panel-heading">
                Logged in user: <b th:inline="text"> [[${#httpServletRequest.remoteUser}]] </b>
                <br>
                <span class="lead">Devices</span></div>
                <div class="panel-body">

                    <div class="table-responsive">
                        <table class="table table-hover">
                                <thead>
                                        <tr>
                                            <th>Device Name</th>

                                        </tr>
                                </thead>
                                <tbody>
                                        <tr ng-repeat="d in details track by d.devHardwareId">
                                            <td>{{d.deviceName}}</td>

                                            <td align="right"><button type="button" ng-click="getPeripheralList(d.devHardwareId)" class="btn btn-success custom-width">Attached Devices</button></td>
                                        </tr>
                                </tbody>
                        </table>      
                    </div>
                </div>

以上代码运作良好。但我的要求是我需要选择一行，当时我需要为特定设备调用getPeripheralList(d.devHardwareId)函数。为此，我使用ui-grid。

所以我在HomeController.js

中添加了功能

$scope.gridOptions = { enableRowSelection: true, enableRowHeaderSelection: false };

$scope.gridOptions.columnDefs = [
    { name: 'Device HardwareId' },
    { name: 'Device Name'},
    { name: 'Device Ip Address'},
    { name: 'Attached Cameras' }
  ];

$scope.gridOptions.multiSelect = false;
$scope.gridOptions.modifierKeysToMultiSelect = false;
$scope.gridOptions.noUnselect = true;
$scope.gridOptions.onRegisterApi = function( gridApi ) {
$scope.gridApi = gridApi;
  };


$scope.toggleRowSelection = function() {
    $scope.gridApi.selection.clearSelectedRows();
    $scope.gridOptions.enableRowSelection = !$scope.gridOptions.enableRowSelection;
    $scope.gridApi.core.notifyDataChange( uiGridConstants.dataChange.OPTIONS);
  };

$scope.deviceGrid = {
    data: 'details',
};

并且也改变了html页面..

<button type="button" class="btn btn-success" ng-click="toggleRowSelection()">Toggle rowSelection</button>
<strong>rowSelection:</strong> 
<span ng-bind="gridApi.grid.options.enableRowSelection"></span>
<div ui-grid="deviceGrid" ui-grid-selection class="grid"></div>

但这并不像我预期的那样有效。它允许选择我不想做的多行，我不明白如何使用ui-grid调用getPeripheralList(d.devHardwareId)函数。（每当我选择一行时，我想打电话给上面的方法）所以我希望得到这里的人的帮助。

如果你不想在网格中选择多行，你只需要在gridOptions中配置它就像这样：

$scope.gridOptions = { enableRowSelection: true, enableRowHeaderSelection: false, multiSelect:false };

如果要在选择行时调用函数，则必须注册gridApi并使用它，您可以执行以下操作：

$scope.gridOptions = { enableRowSelection: true, enableRowHeaderSelection: false, multiSelect:false, 
onRegisterApi: function (gridApi) { 
 gridApi.selection.on.rowSelectionChanged($scope, function (row) {
     // Your call to your function goes here
    });
}};

如何使用ui-grid选择单行？
