javascript - Best way to show/hide a part based on permission level - Angular JS -


i have angularjs single page application there lot of html blocks show users based on permission levels.

the user permission determined service calls , value set based on permission.

$scope.permission = 'admin'

i can use ng-hide/show directives hide blocks based on permission. worried security. changing css display property not authorized can view blocks.

the other option ng-if, using currently. know whether should same routing, more secure, believe. can use ui.router angular module acheive this. right way?

should use ng-hide/show, ng-if or routing?

expecting thoughts.

any appreciated. in advance.

you should create directive such purpose:

app.directive('checkpermissions', ['permissionsservices', function(permissionsservices) {     return {         restrict: 'a',         link: function(scope, elem, attrs, ctrl) {              if (attrs.permissions != '') {                 var haspermission = permissionsservices.hasaccess(attrs.checkpermissions);                  if (false == haspermission) {                     elem.remove();                 }             } else {                 elem.remove();             }         }     }; }]);

html section

<a href="http://some_url" check-permissions="state1.name1" >some url</a> <a ui-sref="state2.name2" check-permissions="state2.name2">state 2</a> <button ng-click="state3.name" check-permissions="state3.name3">state 3</button>

permissionsservices.hasaccess() function in permissionsservices service check if user has access particular state of application. might using angular router or ui router handling states. using ui router code in function below. function return true or false.

permissionsservices.hasaccess = function(statename) {         var hasaccess                   = false;           //some complex checking algorithm based on requirement         hasaccess = true          return hasaccess; };

hope helps!!

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
