使用angular如何实现让checkbox单选,只能选择一个呢?
如图,以下是table中的checkbox选项:
<td width="30" style="text-align: left"><input
type="checkbox" ng-model="checkboxes.items[item.bookingId]" name="flag" ng-click="updateSelection(item.bookingId,checkboxes.items)"/></td>
如果在对象的controller里面实现,只能让其单选,选择一个呢??

试试这个呢
<p ng-controller="MyCtrl">
<p ng-repeat="item in list">
<label><input type="checkbox" ng-model="item.checked" ng-change="onChange(item)">{{item.name}}</label>
</p>
</p>
.controller('MyCtrl', function ($scope) {
$scope.selected = '';
$scope.list = [
{id: 1, name: 'xxx'},
{id: 2, name: 'yyy'},
{id: 3, name: 'zzz'}
];
$scope.onChange = function (item) {
if (item.checked) {
if (!$scope.selected) $scope.selected = item;
if ($scope.selected !== item) item.checked = false;
} else {
$scope.selected = '';
}
}
});
