如何使用UI-Grid选择一行

Question

我正在与大学项目一起工作。我有带有弹簧靴和AngularJS前端的REST API工作。这是我的工作部分。

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

中的工作功能

$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文件中的工作原始表。

<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>

上面的代码运行良好。但是我的要求是，我需要选择一排，当时我需要为特定设备调用getPeripheralList(d.devHardwareId)功能。为此，我正在使用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',
};

也更改了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>

，但这不如我所期望的。它允许选择我不想做的多行，我不知道如何使用UI-Grid调用getPeripheralList(d.devHardwareId)函数。(每当我选择一排我想在上面的方法上调用(，所以我希望从这里得到某人的帮助。

Answer 1

如果您不想允许在网格中选择多个行，则只需在网格中配置它：

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

如果选择一行时要调用功能，则必须注册gridapi并使用它，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
    });
}};

Answer 2

这是答案

$scope.deviceGrid = { 
data:'details',
enableRowSelection: true, 
enableRowHeaderSelection: false, 
enableSelectAll: false,
multiSelect: false,
noUnselect: true,
onRegisterApi: function (gridApi) { 
 gridApi.selection.on.rowSelectionChanged($scope, function (row) {
    var msg = 'row selected ' + row.isSelected;
   console.log(row.entity.devHardwareId);
   HomeService.getPeripheralList(row.entity.devHardwareId).then (function success(response){
    $scope.peripheralDetails = response.data;
    $scope.errorMessage = '';
},
function error(response) {
    $scope.errorMessage = 'Error occured!!!';
    $scope.message = response.data.message;
});
    });
}};
