AngularJS: Add attribute, compile directive


AngularJS: Add attribute, compile directive

will be helpful for those in need In the link phase, you can call $compile(element)(scope) to recompile the element to allow AngularJS to pick up the newly added directive. However, to prevent an infinite loop (since your initial directive will also be re-compiled), you should remove the initial directive's attribute first:
code :
link: function (scope, element) {
    element.removeAttr('test-one');
    element.attr('test-two', '');

    $compile(element)(scope);
}

seems to work fine A better way to use filter in a directive is to inject $filter service:
code :
$filter('amDateFormat')($scope.datetime, 'D MMMM HH:mm');
.directive('titleDate', ['$filter', function () {
    return {
        restrict: 'A',
        scope: {
            datetime: '=titleDate'
        },

        link: function($scope, element) {
            element.attr('title', $filter('amDateFormat')($scope.datetime, 'D MMMM HH:mm'));             
        }
    }]
});

To fix the issue you can do I'm afraid you cannot add directives dynamically to the element that contains your directive. The reason is that your compile function will be called after Angular has processed the directive's element and determined what the directives are attached to it. Adding another attribute at this point is too late, discovery has already taken place.
There may be ways to do it that I don't know of (and I would be interested in seeing any stable, non-hackish one).
code :
<button ng-click="ctrl.click()" ng-disabled="ctrl.disabled" disabled-button>
.directive('disabledButton', function($parse) {
    return {
        restrict: 'A',
        transclude: true,
        scope: {
        },
        template: '<span ng-show="disabled">X</span><span ng-transclude></span>',
        link: function (scope, elem, attrs) {
            var disabled = $parse(attrs.ngDisabled);
            scope.disabled = false;
            scope.$watch(
                function() {
                    return disabled(scope.$parent);
                },
                function(newval) {
                    scope.disabled = newval;
                }
            );
        }
    };
})
AngularJS - $compile a Directive with an Object as an Attribute Parameter

AngularJS - $compile a Directive with an Object as an Attribute Parameter

like below fixes the issue When I use $compile to create and bind a directive, how can I also add a variable as an attribute? The variable is an object. , It is quite easy, just create new scope and set data property on it.
code :
angular.module('app', []);

angular
  .module('app')
  .directive('myDirective', function () {
    return {
      restrict: 'E',
      template: 'record = {{record}}',
      scope: {
        record: '='
      },
      link: function (scope) {
        console.log(scope.record);
      }
    };
  });

angular
  .module('app')
  .directive('example', function ($compile) {
    return {
      restrict: 'E',
      link: function (scope, element) {
        var data = {
          name: 'Fred'
        };
        
        var newScope = scope.$new(true);
        newScope.data = data;

        var dirCode = '<my-directive data-record="data"></my-directive>';

        var el = $compile(dirCode)(newScope);
    
        element.append(el);
      }
    };
  });
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.js"></script>

<div ng-app="app">
  <example></example>
</div>

hope this fix your issue Instead of adding and compiling an ng-class directive, simply compute and manipulate the classes in the link function directly:
code :
app.directive('hasError', () => {
    return {
        restrict: 'A',
        link: (scope,elem,attrs) => {
            scope.$watch(
               () => {
                  let expn = scope.$eval(attrs.hasError);
                  return expn && expn.$touched && expn.$invalid;
               },
               (value) => {
                    elem.removeClass('has-error');
                    value && elem.addClass('has-error');
               }
            );
        }
    }
});
