Assessing the usage of $parse in a directive within an ng-repeat loop in Angular version 1.4.5

I'm attempting to utilize $parse to analyze the expression of an attribute of a directive within an ng-repeat loop. Here is an example of the HTML:

<body ng-app="hello" ng-controller="control">
<div ng-repeat="a in array" my-dir="a.one == 1"></div>
</body>

and the Angular directive:

angular.module('hello', [])
.controller('control', function($scope){
  $scope.array = [{
    one: 1,
    two: 2
  },
  {
    one: 3,
    two: 4
  }];
})
.directive('myDir', function($parse){
  return {
    restrict: 'A',
    link: function(scope, elem, attrs){
      var hash = $parse(attrs.myDiv);
      // I am seeking a method to evaluate this expression
      // without needing to define it as my-dir="array[$index].item == 1"
      // similar to what is done with other Angular directives.
      console.log(hash(scope)); // This returns undefined, as a.one cannot be found in the scope.
    },
  };

});

The problem with this approach is that $parse is attempting to locate the a.one property within the scope and that property does not exist.

I could use my-dir="array[$index].one == 1" but this is not user-friendly for the users of the directive (they would need to know the scope they are working with).

Answer №1

The error is in using myDiv instead of myDir.
