選択した行への双方向バインディングのディレクティブ。kendo-grid ディレクティブと同じ要素に配置する必要があります。
タイプスクリプトのバージョン:
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(
() => $scope.row,
(newValue, oldValue) => {
if (newValue !== undefined && newValue != oldValue) {
if (newValue == null)
grid.clearSelection();
else {
var index = grid.dataSource.indexOf(newValue);
if (index >= 0)
grid.select(grid.element.find("tr:eq(" + (index + 1) + ")"));
else
grid.clearSelection();
}
}
});
});
},
scope: {
row: "=gridSelectedRow"
}
};
}
Javascript のバージョン
function kendoGridSelectedRowsDirective() {
return {
link: function ($scope, element) {
var unregister = $scope.$parent.$on("kendoWidgetCreated", function (event, grid) {
if (unregister)
unregister();
// Set selected rows on selection
grid.bind("change", function (e) {
var selectedRows = this.select();
var selectedDataItems = [];
for (var i = 0; i < selectedRows.length; i++) {
var dataItem = this.dataItem(selectedRows[i]);
selectedDataItems.push(dataItem);
}
if ($scope.row != selectedDataItems[0]) {
$scope.row = selectedDataItems[0];
$scope.$root.$$phase || $scope.$root.$digest();
}
});
// Reset selection on page change
grid.bind("dataBound", function () {
$scope.row = null;
$scope.$root.$$phase || $scope.$root.$digest();
});
$scope.$watch(function () { return $scope.row; }, function (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"
}
};
}
