Angular UI 网格 - 选定行上的单击事件

Angular UI Grid - Click event on selected row

目标

我有一个 UI 网格。当我点击一行时,它应该被选中,并且应该调用一个以该行作为参数的函数。

当前方法

我使用以下配置代码生成网格:

$scope.gridOptions = {
        enableFiltering: true,
        enableRowHeaderSelection: false,
        enableRowSelection: true,
        multiSelect: false,
        noUnselect: true,
        onRegisterApi: function (gridApi) {
            $scope.gridApi = gridApi;
            $scope.gridApi.selection.on.rowSelectionChanged($scope, function (row) {
                var name = row.entity.name;
                $scope.addToQueue(name);
            });
        }
    };

问题

当我实际更改选择时(如函数名称所示),上面的代码运行良好。但是应该可以多次向队列中添加一行。所以即使已经选择了该行,我也想调用 $scope.addToQueue(name)

将对addToQueue函数的调用移动到gridApi.grid.element.on('click'...)函数,并将row存储在gridApi.selection.on.rowSelectionChanged函数中:

$scope.gridOptions.onRegisterApi = function (gridApi) {
  //set gridApi on scope
  $scope.gridApi = gridApi;
  gridApi.selection.on.rowSelectionChanged($scope, function (row) {
    $scope.gridApi.grid.appScope.lastSelectedRow = row;
  });

  gridApi.grid.element.on('click', function (ev) {
    if ($scope.gridApi.grid.appScope.lastSelectedRow) {
      // affect only rows (not footer or header)
      if (ev.target.className.includes('ui-grid-cell-contents')) {
        var name = $scope.gridApi.grid.appScope.lastSelectedRow.entity.name;
        $scope.addToQueue(name);
      }
    }
  });
};

$scope.addToQueue = function addToQueue (name) {
  console.log('addToQueue fired, name = ' + name);
};

对于要 selected 的行,单击它时,我使用以下内容:

对所有列使用 selectionCellTemplate:

 var selectionCellTemplate = '<div class="ngCellText ui-grid-cell-contents">' +
               ' <div ng-click="grid.appScope.rowClick(row)">{{COL_FIELD}}</div>' +
               '</div>';

 $scope.gridOptions.columnDefs = [        
    { name: 'name', displayName: 'Name', width: '15%', cellTemplate: selectionCellTemplate },       
   ];

然后将 rowClick() 方法定义为:

 $scope.rowClick = function (row) {       
    var index = row.grid.renderContainers.body.visibleRowCache.indexOf(row);
    $scope.gridApi.selection.selectRow($scope.gridOptions.data[index]);
};

我也定义了 multiselect 为 true

$scope.gridOptions.multiSelect = true;

所以行点击将 select 该行并将其添加到 selected 行。您可以访问这些 selected 行(它为每一行触发 select/unselect):

$scope.gridOptions.onRegisterApi = function (gridApi) {
    //set gridApi on scope
    $scope.gridApi = gridApi;        
    gridApi.selection.on.rowSelectionChanged($scope, doSelection);
};

function doSelection(row) {      
    _.each($scope.gridApi.selection.getSelectedRows(), function (row) {
        //Do something //It is triggered for each row select/unselect         
    });
}

或 selected 行可以随时访问:

  $scope.gridApi.selection.getSelectedRows()

批准的答案对我有用,但这里有一个小错误...

var selectionCellTemplate = '<div class="ngCellText ui-grid-cell-contents">' +
           ' <div ng-click="grid.appScope.rowClick(row)">{{COL_FIELD}}</div>' +
           '</div>';

我需要将其更改为...

var selectionCellTemplate = '<div class="ngCellText ui-grid-cell-contents"
           ng-click="grid.appScope.rowClick(row)">' +
           '<div>{{COL_FIELD}}</div>' +
           '</div>';

您会注意到我将 ng-click 移到了父级 div。 这是必需的,因为如果单元格为空,则不会触发 ng-click 事件。
