从工厂设置时，将 false 设置为范围变量不起作用

Question

我有一个导航下拉菜单，我想隐藏下拉菜单中基于工厂值的一些选项。我使用ng-show的选项，我想隐藏或显示基于从工厂的值。

当我将它直接设置为false而不使用factory时，它会工作，并且我不会在下拉菜单中看到这些选项。

这是我从工厂获取数据的方式:

$scope.mstrClientLStatus=userDetailsFactory.getUserDetailsFromFactory().mstrClientLStatus; 
console.log($scope.mstrClientLStatus) 
//it is false but doesn't hide

当我将上述设置为直接false时，选项被隐藏。

$scope.mstrClientLStatus= false //works and the options are hidden

I console.log和$scope.mstrClientLStatus在下一行，它是假的，但它仍然显示下拉菜单中的选项。

html:

<li ng-show="mstrClientLStatus"> //this is what I want to hide

整个工厂代码:

.factory('userDetailsFactory',function(){
var user = {};
return {
    setUserDetailsInFactory : function(val,$cookies,favoriteCookie,put,get){        
        user.useridFromSession = val[0].UserId;
        user.usernameFromSession = val[0].UserName;
        user.userroleFromSession = val[0].Role;
        user.clientidFromSession = val[0].ClientId;
        user.ip = "http://192.168.2.100:5000";
        user.mstrDashBoardSession = val[0].DashBoard;
        user.mstrClientLSession = val[0].ClientLogin;
        user.ClientRegistrationSession = val[0].ClientRegistration;
        user.mstrBustypeSession = val[0].mstrBustype;
        user.mstrBusCategorySession = val[0].mstrBusCategory;
        user.mstrSeatLayoutSession = val[0].mstrSeatLayout;
        user.mstrDesignationSession = val[0].mstrDesignation;
        user.mstrBusSession = val[0].mstrBus;
        user.mstrRouteSession = val[0].mstrRoute;
        user.mstrBranchSession = val[0].mstrBranch;
        user.mstrDeviceSession = val[0].mstrDevice;
        user.mstrServiceSession = val[0].mstrService;
        user.mstrRouteFareSession = val[0].mstrRouteFare;
        user.mstrNewUserSession = val[0].mstrNewUser;
        user.mstrPDAServiceAssignSession = val[0].mstrPDAServiceAssign;
        user.mstrUserRightSession = val[0].mstrUserRight;
        user.rptTripSheetSession = val[0].rptTripSheet;
        user.rptTripSummarySession = val[0].rptTripSummary;
        user.rptCargoSummaryFromSession = val[0].rptCargoSummary;
        user.rptBusMonthSession = val[0].rptBusMonth;
        user.rptDeviceSession = val[0].rptDevice;

        //console.log(user.useridFromSession);
        //console.log(user.usernameFromSession);
        //console.log(user.userroleFromSession);
    },getUserDetailsFromFactory : function(){
        return user;
    }
};

Answer 1

我的同事建议这样做，虽然它是一个变通方法。我认为:

if(userDetailsFactory.getUserDetailsFromFactory().mstrClientLStatus=="true"){
    $scope.mstrClientLStatus= true;
}

Answer 2

这很奇怪，因为你在控制器中编写代码，可能是摘要循环的问题，你只需要把你的操作放在超时块中让它在摘要循环中注册，

  $timeout(function() {
   $scope.mstrClientLStatus = userDetailsFactory.getUserDetailsFromFactory().mstrClientLStatus;
   $scope.$apply()
 })
