在本地存储AngularJs中设置值

Question

我正在尝试在localStorage中设置值。函数调用后，我试图更改该值。请检查我的代码

这是我的js角函数

 localStorage.setItem("popupstatus", true);
    $scope.loadInitialPopUp = function (){
        if (  localStorage.getItem("popupstatus") === true){ //only show if they haven't seen it.
        $scope.openPopup();
    }
    }

    $scope.openPopup = function () {
        var modalInstance = $uibModal.open({
            animation: true,
            ariaLabelledBy: 'modal-title',
            ariaDescribedBy: 'modal-body',
            controller: 'popupPeriodCtrl',
            scope: $scope,
            resolve: {
            },
            templateUrl: 'modules/popup-period/popup-period.html'
        });
        localStorage.setItem("popupstatus", false);
    };

我正在HTML页面中调用上述功能

<div ng-init="loadInitialPopUp()"> </div>

我需要从localStorage中设置的值加载此弹出窗口。我该怎么办？

getItem方法将返回一个String而不是一个布尔值。尝试做

if (Boolean(localStorage.getItem("popupstatus"))){
    $scope.openPopup();
}
