angular ui-grid 事件:行被选中 [英] angular ui-grid event: row selected

问题描述

我正在尝试根据 ui-grid 上的行选择启用/禁用按钮.如果未选择任何行，则该按钮处于禁用状态.

I am trying to enable/disable a button based on the selection of a row on a ui-grid. If there are no rows selected, the button is disabled.

我发现这个 plunkr 使用旧的 ng-grid 方式在选择一行后触发事件.

I found this plunkr with the old ng-grid way of firing an event after a row is selected.

  $scope.gridOptions = { 

  data: 'myData', 
  selectedItems: $scope.selections,
  enableRowSelection: true,

  afterSelectionChange:function() {
        if ($scope.selections != "" ) {
            $scope.disabled = false;
        } else {
            $scope.disabled = true;
        }
  }
};

不幸的是它不起作用，我在 ui-grid 文档中没有发现此类事件的迹象.

Unfortunately it does not work, and I have found no sign of such event in the ui-grid documentation.

如何使用 ui-grid 实现这一点?

How can I achieve that with ui-grid?

推荐答案

在 ui-grid 中，您在rowSelectionChanged"事件上注册了一个回调函数

In ui-grid, you register a callback function on the event "rowSelectionChanged"

 $scope.gridOptions.onRegisterApi = function (gridApi) {
                $scope.gridApi = gridApi;
                gridApi.selection.on.rowSelectionChanged($scope, callbackFunction);
                gridApi.selection.on.rowSelectionChangedBatch($scope, callbackFunction);
            }
 }

 function callbackFunction(row) { 
    var msg = 'row selected ' + row.isSelected; $log.log(msg); 
 })

我觉得你应该看看ui-grid中的教程页面:http://ui-grid.info/docs/#/tutorial/210_selection.在我看来，API 页面很糟糕:(.

I think you should take a look at the tutorial page in ui-grid: http://ui-grid.info/docs/#/tutorial/210_selection. The API page sucks, in my opinion :(.
