ui-grid 3.0.0中的selectedItem

Question

我正在测试角度ui-grid 3.0.0.以下是旧版本的示例代码,selectedItems在选中时应包含一些对象.在版本3中,它似乎不起作用.有人遇到过同样的行为吗？

Angularjs版本:1.3.11 Angular-ui-grid:3.0.0-rc.16这里是我控制器的一些提取代码:

$scope.gridOptions = {  };
$scope.mySelections = [];

$scope.gridOptions = {
    enableRowSelection: true,
    enableRowHeaderSelection: false,
    modifierKeysToMultiSelect: true,
    multiSelect: true,
    pagingPageSize: 25,
    useExternalPagination: true,
    useExternalSorting: true,
    selectedItems: $scope.mySelections
};

$scope.changeDelete = function () {
    $log.debug('Selection length = ' + $scope.mySelections.length);
    if ($scope.mySelections.length > 0) {
        $location.path("/EREditHospitalChange/");
    }
    $location.path("/EREditHospitalChange/LYNDA");

}

// mySelections.length始终为0.

他是html页面中的网格声明:

<div ui-grid="gridOptions" ui-grid-selection ui-grid-pagination ui-grid-edit class="grid"></div>

<pre>{{mySelections}}</pre>
</fieldset>
<button ng-click="changeDelete()">Change/Delete</button>

[] This is what is visible in {{mySelections}}

您应该使用gridApi.selection.请参阅http://ui-grid.info/docs/#/api/ui.grid.selection.api:PublicApi和教程中的文档:http://ui-grid.info/docs/#/tutorial/210_selection

在您的gridOptions中,添加以下内容:

$scope.mySelections = [];

$scope.gridOptions = {
    enableRowSelection: true,
    enableRowHeaderSelection: false,
    modifierKeysToMultiSelect: true,
    multiSelect: true,
    pagingPageSize: 25,
    useExternalPagination: true,
    useExternalSorting: true,
    // Addition:
    onRegisterApi: function (gridApi) {
        $scope.gridApi = gridApi;
        gridApi.selection.on.rowSelectionChanged($scope,function(rows){
            $scope.mySelections = gridApi.selection.getSelectedRows();
        });
    }
};

这是关于Plunker的一个工作示例:http://plnkr.co/edit/u5pzISURTnvPBm9FyiLr？p = preview

你也可以删除$scope.gridOptions = { }它,因为声明对象就像你之后用属性一样声明对象是完全有效的
