我有一个UI网格。当我点击一行时,它应该被选中,并且应该调用以行作为参数的函数。
当前方法
我使用以下配置代码生成Grid:
$scope.gridOptions = {
enableFiltering: true,
enableRowHeaderSelection: false,
enableRowSelection: true,
multiSelect: false,
noUnselect: true,
onRegisterApi: function (gridApi) {
$scope.gridApi = gridApi;
$scope.gridApi.selection.on.rowSelectionChanged($scope, function (row) {
var name = row.entity.name;
$scope.addToQueue(name);
});
}
};
问题
当我实际更改选择时(作为函数的名称建议),上面的代码很有效。但应该可以多次向队列添加一行。因此,即使已经选择了行,我也想调用$scope.addToQueue(name)
。

对于要选择的行,单击它时,我使用以下内容:
对所有列使用selectionCellTemplate:
var selectionCellTemplate = '<div class="ngCellText ui-grid-cell-contents">' +
' <div ng-click="grid.appScope.rowClick(row)">{{COL_FIELD}}</div>' +
'</div>';
$scope.gridOptions.columnDefs = [
{ name: 'name', displayName: 'Name', width: '15%', cellTemplate: selectionCellTemplate },
];
然后将rowClick()方法定义为:
$scope.rowClick = function (row) {
var index = row.grid.renderContainers.body.visibleRowCache.indexOf(row);
$scope.gridApi.selection.selectRow($scope.gridOptions.data[index]);
};
我还将multiselect定义为真实
$scope.gridOptions.multiSelect = true;
因此,行单击将选择该行并将其添加到所选行。您可以访问这些选定的行(它为每行选择/取消选择触发):
$scope.gridOptions.onRegisterApi = function (gridApi) {
//set gridApi on scope
$scope.gridApi = gridApi;
gridApi.selection.on.rowSelectionChanged($scope, doSelection);
};
function doSelection(row) {
_.each($scope.gridApi.selection.getSelectedRows(), function (row) {
//Do something //It is triggered for each row select/unselect
});
}
或者可以随时访问所选行:
$scope.gridApi.selection.getSelectedRows()

将对 addToQueue 的调用移至gridApi.grid.element.on('click'...)
函数,并将行存储在gridApi.selection.on.rowSelectionChanged
函数中:
$scope.gridOptions.onRegisterApi = function (gridApi) {
//set gridApi on scope
$scope.gridApi = gridApi;
gridApi.selection.on.rowSelectionChanged($scope, function (row) {
$scope.gridApi.grid.appScope.lastSelectedRow = row;
});
gridApi.grid.element.on('click', function (ev) {
if ($scope.gridApi.grid.appScope.lastSelectedRow) {
// affect only rows (not footer or header)
if (ev.target.className.includes('ui-grid-cell-contents')) {
var name = $scope.gridApi.grid.appScope.lastSelectedRow.entity.name;
$scope.addToQueue(name);
}
}
});
};
$scope.addToQueue = function addToQueue (name) {
console.log('addToQueue fired, name = ' + name);
};

批准的答案对我有用,但对于这里的一个小错误......
var selectionCellTemplate = '<div class="ngCellText ui-grid-cell-contents">' +
' <div ng-click="grid.appScope.rowClick(row)">{{COL_FIELD}}</div>' +
'</div>';
我需要将其更改为......
var selectionCellTemplate = '<div class="ngCellText ui-grid-cell-contents"
ng-click="grid.appScope.rowClick(row)">' +
'<div>{{COL_FIELD}}</div>' +
'</div>';
您会注意到我将ng-click移动到父div。 这是必需的,好像一个单元格是空的,ng-click事件不会触发。
