Authorization code for access control - angularjs

Question

How to write a angularjs code to check if the value passing is already exist in the array and if exists, user should be given access rights, if not, he should not be given rights

Answer 1

I think this should work
In your HTML you need to bind the ng-click with a button that will check the privilege and perform accordingly. Lets say the button is like this
<button type="button" ng-click="checkPrivilege();">Check Privilege</button>
Inside your controller you need to do some operations like this
//say, this is our privilege JSON
$scope.privilege = [
{
accessName: "ACCOUNT_ADD",
roles:['ADMIN','MANAGER']
},
{
accessName: "ACCOUNT_DELETE",
roles:['ADMIN']
}
];
$scope.checkPrivilege = function(){
//first you need to find out the role of the logged in user, lets say
//you get the role value from getLoggedInUserRole() function
$scope.userRole = getLoggedInUserRole();
//lets say the selected access name is 'ACCOUNT_ADD'
$scope.allowedAccessName = "ACCOUNT_ADD";
angular.forEach($scope.privilege, function(value, key) {
var privilegedRoles = privilege[key].roles;
var privilegedAccessName = privilege[key].accessName;
//check if the json object contains the same accessName which we need
if($scope.allowedAccessName === privilegedAccessName){
//check if the role is allowed or not for this user
if( privilegedRoles.indexOf(userRole) > -1 ){
//the logged in user has this privilege to accessName
break;
}else{
// the logged in user has no access to this accessName
}
}
});
}
You can look at the comment and understand. This code may not be exactly the same which you are expecting but you will surely get an idea about how you can achieve your goal.
