Question

我正在尝试从AngularJS中的KendoUI Grid处理选择事件。

我的代码工作如下。然而，感觉就像是一个非常讨厌的方式来获取所选行的数据。特别是使用_data。有没有更好的方法呢？我的做法是否错误？

<div kendo-grid k-data-source="recipes" k-selectable="true" k-sortable="true" k-pageable="{'refresh': true, 'pageSizes': true}"
            k-columns='[{field: "name", title: "Name", filterable: false, sortable: true},
            {field: "style", title: "Style", filterable: true, sortable: true}]' k-on-change="onSelection(kendoEvent)">
</div>

$scope.onSelection = function(e) {
  console.log(e.sender._data[0].id);
}

Answer 1

请尝试以下方法：

    $scope.onSelection = function(kendoEvent) {
        var grid = kendoEvent.sender;
        var selectedData = grid.dataItem(grid.select());
        console.log(selectedData.id);
    }

Answer 2

加入派对的时间相当晚，有一种直接的方法可以在不达到网格对象的情况下完成：

标记上的

：

k-on-change="onSelection(data)"

代码中的

：

$scope.onSelection = function(data) {
    // no need to reach the for the sender
}

请注意，如果需要，您仍然可以发送selected，dataItem，kendoEvent或columns。

如何使用angular指令执行此操作的快速示例。

请注意，我通过click事件和DOM句柄获取对底层kendo网格的引用。

    //this is a custom directive to bind a kendo grid's row selection to a model
    var lgSelectedRow = MainController.directive('lgSelectedRow', function () {
        return {
            scope: {
                //optional isolate scope aka one way binding
                rowData: "=?"
            },
            link: function (scope, element, attributes) {
                //binds the click event and the row data of the selected grid to our isolate scope
                element.bind("click", function(e) {
                    scope.$apply(function () {
                        //get the grid from the click handler in the DOM
                        var grid = $(e.target).closest("div").parent().data("kendoGrid");
                        var selectedData = grid.dataItem(grid.select());
                        scope.rowData = selectedData;
                    });
                });
            }
        };
    });

对所选行进行双向绑定的指令。应该放在同一个元素上作为剑道网格指令。

打字稿版本：

interface KendoGridSelectedRowsScope extends ng.IScope {
        row: any[];
    }

// Directive is registered as gridSelectedRow
export function kendoGridSelectedRowsDirective(): ng.IDirective {
        return {
            link($scope: KendoGridSelectedRowsScope, element: ng.IAugmentedJQuery) {

                var unregister = $scope.$parent.$on("kendoWidgetCreated", (event, grid) => {
                    if (unregister)
                        unregister();

                    // Set selected rows on selection
                    grid.bind("change", function (e) {

                        var selectedRows = this.select();
                        var selectedDataItems = [];

                        for (var i = 0; i < selectedRows.length; i++) {
                            var dataItem = this.dataItem(selectedRows[i]);
                            selectedDataItems.push(dataItem);
                        }

                        if ($scope.row != selectedDataItems[0]) {

                            $scope.row = selectedDataItems[0];
                            $scope.$root.$$phase || $scope.$root.$digest();
                        }
                    });


                    // Reset selection on page change
                    grid.bind("dataBound", () => {
                        $scope.row = null;
                        $scope.$root.$$phase || $scope.$root.$digest();
                    });

                    $scope.$watch(
                        () => $scope.row,
                        (newValue, oldValue) => {
                            if (newValue !== undefined && newValue != oldValue) {
                                if (newValue == null)
                                    grid.clearSelection();
                                else {
                                    var index = grid.dataSource.indexOf(newValue);
                                    if (index >= 0)
                                        grid.select(grid.element.find("tr:eq(" + (index + 1) + ")"));
                                    else
                                        grid.clearSelection();
                                }
                            }
                        });
                });
            },
            scope: {
                row: "=gridSelectedRow"
            }
        };
    }
