我有一些复选框:
<input type='checkbox' value="apple" checked>
<input type='checkbox' value="orange">
<input type='checkbox' value="pear" checked>
<input type='checkbox' value="naartjie">
我想绑定到我的控制器中的一个列表，这样每当一个复选框被更改时，控制器就会维护一个包含所有选中值的列表，例如，['apple'， 'pear']。
Ng-model似乎只能将一个复选框的值绑定到控制器中的一个变量。
是否有其他方法可以将这四个复选框绑定到控制器中的列表?
当前回答
我在控制器中放了一个数组。
$scope.statuses = [{ name: 'Shutdown - Reassessment Required' },
{ name: 'Under Construction' },
{ name: 'Administrative Cancellation' },
{ name: 'Initial' },
{ name: 'Shutdown - Temporary' },
{ name: 'Decommissioned' },
{ name: 'Active' },
{ name: 'SO Shutdown' }]
在标记上，我添加了如下内容
<div ng-repeat="status in $scope.statuses">
<input type="checkbox" name="unit_status" ng-model="$scope.checkboxes[status.name]"> {{status.name}}
<br>
</div>
{{$scope.checkboxes}}
输出如下，在控制器中，我只需要检查它是真还是假;选中为True，未选中为null /false。
{
"Administrative Cancellation":true,
"Under Construction":true,
"Shutdown - Reassessment Required":true,
"Decommissioned":true,
"Active":true
}
希望这能有所帮助。
其他回答
我认为最简单的解决方法是使用'select'并指定'multiple':
<select ng-model="selectedfruit" multiple ng-options="v for v in fruit"></select>
否则，我认为您将不得不处理该列表来构造该列表 (通过$watch()用复选框绑定模型数组)。
看看这个有效管理复选框列表的指令。我希望这对你有用。 检查表模型
看看这个:清单模型。
它可以使用JavaScript数组和对象，它可以使用静态HTML复选框，而不需要ng-repeat
<label><input type="checkbox" checklist-model="roles" value="admin"> Administrator</label>
<label><input type="checkbox" checklist-model="roles" value="customer"> Customer</label>
<label><input type="checkbox" checklist-model="roles" value="guest"> Guest</label>
<label><input type="checkbox" checklist-model="roles" value="user"> User</label>
JavaScript方面:
var app = angular.module("app", ["checklist-model"]);
app.controller('Ctrl4a', function($scope) {
$scope.roles = [];
});
灵感来自Yoshi上面的帖子。 这是钱。
