UniquePage.html

<div ng-controller="UniquePageCtrl">
    <unique-custom-directive arg1="{{currentObj.name}}"></my-custom-directive>
<div>

in UniquePageCtrl.js (Controller)

app.controller("UniquePageCtrl", ["$scope", function ($scope) {
          $scope.currentObj = {"name":"Kaitlyn"};
    }]);

And here is how the directive code looks:

app.directive("uniqueCustomDirective", [function () {
    return {
        restrict: "E",
        controller: "UniqueDirCtrl"
    };
}]);

This is the controller of the directive:

app.controller("UniqueDirCtrl", ["$attrs", function ($attrs) {
      var arg = $attrs.arg1;
      alert('Argument '+arg);
}]);

The alert only displays "{{currentObj.name}}" instead of the actual value of the name property.

Please share any suggestions on how to resolve this issue.

Thank you.

Using $attrs for a controller can be confusing, it's easier to just stick with $scope.

myView.html

<div ng-controller="MyViewController">
    <my-custom-directive arg="{{selectedItem.name}}"></my-custom-directive>
<div>

myViewController.js (Controller)

app.controller("MyViewController", ["$scope", function ($scope) {
          $scope.selectedItem = {"name":"Alex"};
    }]);

myCustomDirective

app.directive("myCustomDirective", [function () {
    return {
        restrict: "E",
        controller: "MyCustomDirectiveController"
    };
}]);

Directive's controller (remember to use $scope instead of $attrs),

app.controller("MyCustomDirectiveController", ["$scope", function ($scope) {
      var argument = $scope.arg;
      alert('Argument: '+argument);
}]);

Answer №2

Stop trying to access the attribute directly from your controller; utilize the link function in your directive instead.

app.directive("anotherDirective", [function () {
    return {
        restrict: "A",
        controller: "AnotherCtrl",
        link: function(scope, element, attr) {
            console.log(attr.value);
        }
    };
}]);
