获取angularjs ui-grid的选定行

Question

我已经查看了关于这个 ui-grid 的多篇文章，它让我很适合。我正在尝试获取选定的行对象。我要么得到一个未定义的，要么无法读取“getSelectedRows”的属性。任何帮助是极大的赞赏。

我从这篇文章here开始，文档似乎也不是那么好。

这是我的代码：

        vm.gridOptions = {
        enableRowSelection: false,
        enableSelectAll: false,
        showGridFooter:true

    };

    vm.gridOptions.columnDefs = [
        { name: 'productName' },
        { name: 'unitPrice' }
    ];

    vm.gridOptions.multiSelect = false;

    vm.getSelectedRows = function () {
        vm.mySelectedRows = vm.gridApi.selection.getSelectedRows();
    }

     productDataService.getProductList()
         .then(function (result) {                 
             vm.gridOptions.data = result.data;
             vm.mySelectedRows = vm.gridApi.selection.getSelectedRows();<--Property undefined error here
             $timeout(function() {
                 if (vm.gridApi.selection.selectedRow) {
                     vm.gridApi.selection.selectRow(vm.gridOptions.data[0]);
                 }
             });
         });

    vm.gridOptions.onRegisterApi = function(gridApi) {
        vm.gridApi = gridApi;
    }

希望这可以帮助：

angular.module('app', ['ui.grid', 'ui.grid.selection'])
  .controller('MainCtrl', ['$scope', '$timeout', function($scope, $timeout) {
    var vm = this;
    vm.gridOptions = {
      enableRowSelection: false,
      enableSelectAll: false,
      showGridFooter:true,
      data: [{productName: "Moroni", unitPrice: 50},
             {productName: "Tiancum", unitPrice: 43},
             {productName: "Jacob", unitPrice: 27},
             {productName: "Nephi", unitPrice: 29},
             {productName: "Enos", unitPrice: 34}]
    };
    vm.gridOptions.columnDefs = [
        { name: 'productName' },
        { name: 'unitPrice' }
    ];
    vm.gridOptions.multiSelect = false;
    vm.getSelectedRows = function () {
        vm.mySelectedRows = vm.gridApi.selection.getSelectedRows();
    }
    vm.getProductList = function() {
      vm.gridOptions.data = vm.resultSimulatedData;
      vm.mySelectedRows = vm.gridApi.selection.getSelectedRows(); //<--Property undefined error here
      if (vm.mySelectedRows[0]) {
        alert('Selected Row: ' + vm.mySelectedRows[0].productName + ', ' + vm.mySelectedRows[0].unitPrice + '.');
      } else {
        alert('Select a row first');
      }
      $timeout(function() {
          if (vm.gridApi.selection.selectedRow) {
              vm.gridApi.selection.selectRow(vm.gridOptions.data[0]);
          }
      });
    };
    vm.gridOptions.onRegisterApi = function(gridApi) {
      vm.gridApi = gridApi;
    };
    vm.resultSimulatedData = [{productName: "Moroni1", unitPrice: 50},

                               {productName: "Enos1", unitPrice: 34}];
    return vm;
  }]);
