AngularJS-从ui网格导出PDF/CSV时出错

嗨，我遵循的程序与下面的程序相同

它的工作正常。但我只是添加了下面的代码，以便在gridOptions之后从表中导出数据，如下所示，给出错误gridApi未定义，请建议，但没有

init（）

/

then（）

，simple controller export正在工作

$scope.gridOptions = {
    paginationPageSizes: [25, 50, 75],
    paginationPageSize: 25,
    useExternalPagination: true,
    useExternalSorting: true,
    rowTemplate : 'rowTemplate.html',
    columnDefs: [
      { name: $scope.translate.EQUIPMENT_NAME, field: 'equipmentName' },
      { name: $scope.translate.EQUIPMENT_TYPE, field: 'equipmentType.equipmentType' },
      { name: $scope.translate.CREATION_DATE, field: 'creationDate' },
      { name: $scope.translate.ACTION, cellTemplate:'cellTemplate.htm'}
    ],
      exporterSuppressColumns: [ $scope.translate.ACTION ],
    onRegisterApi: function(gridApi) {
     console.log('grid table fun');
      //currentSortColumns = $scope.gridOptions.columnDefs[0].field;
      $scope.gridApi = gridApi;
      //$scope.gridApi.core.on.sortChanged( $scope, $scope.sortChanged );
      //$scope.sortChanged($scope.gridApi.grid, [ $scope.gridOptions.columnDefs[0] ] );
      gridApi.pagination.on.paginationChanged($scope, function (newPage, pageSize) {
        paginationOptions.pageNumber = newPage;
        paginationOptions.pageSize = pageSize;
        //$scope.sortChanged($scope.gridApi.grid, currentSortColumns );
        getPage();
      });  
    }
  };
    $scope.export = function(){
         //alert("hii");
    console.log($scope.export_format);
    if ($scope.export_format == 'csv') {
      var myElement = angular.element(document.querySelectorAll(".custom-csv-link-location"));
      $scope.gridApi.exporter.csvExport( $scope.export_row_type, $scope.export_column_type, myElement );
    } else if ($scope.export_format == 'pdf') {
      $scope.gridApi.exporter.pdfExport( $scope.export_row_type, $scope.export_column_type );
    };
  };
