我正在尝试使用cookie来隐藏和显示表中的列,而不是将所选的复选框值存储在数据库中。我遇到的问题是,当用户再次启动模式时,我无法显示先前选择的复选框值。我正在尝试使用 ng-init 来取回值,并将复选框设置为 true (如果已选中)。

在上面的代码中,用户可以选择任何可用的选项。一旦用户选择了一个或多个复选框,那么该值就会被传递给angularjs控制器,然后在其中设置一个cookie。每当我检查浏览器工具或视图本身时,我从cookie中获得的值都是 true 。
Angularjs控制器
...
// stored cookie columns for collections table
...
$scope.cookie_coll_phone = $cookies.get('coll_phone');
...
// add more columns to collections list
$scope.collectionColumns = function() {
var modalInstance = $uibModal.open({
animation: true,
templateUrl: '/js/modals/collection-columns.html',
size: 'md',
resolve:{
},
controller: function ($scope,$uibModalInstance) {
...
$scope.cookie_coll_phone = $cookies.get('coll_phone');
...
$scope.cancel = function () {
$uibModalInstance.dismiss('cancel');
};
$scope.save = function() {
...
$cookies.put('coll_phone', $scope.columns.coll_phone);
...
toaster.pop('success', 'Success!', 'Additional column(s) have been added.');
location.assign('/collections');
$uibModalInstance.close();
};
}
});
modalInstance.result.then(function (data) {
},function () {
});
};
...
非常感谢任何有关此问题的帮助

我正在将复选框值保存到localStorage。 在控制器中只检查是否有我的localStorage属性。这是我的3个复选框的示例。
vm.checkedCheckBoxes = window.localStorage.checkboxes ? JSON.parse(window.localStorage.checkboxes) : [false, false, false];
之后,我只是使用&#39; ng-checked&#39;在html。
