Question

我打算只关注指令控制器的使用。所以，pl回答了我提到的每个指令用法实例所提到的相同错误，在指令中提到的控制器部分中，angular会出现一次。

＆＃13;

//module declaration 
var app = angular.module('myApp',[]);

//controller declaration
app.controller('myCtrl',function($scope){
$scope.name = "Peter";
});

//app declaration
app.directive('myStudent',function(){
return{
	template: "Hi! Dear!! {{name}}<br/>",
	controller:function(scope, elem, attr){
		console.log("controller");
	}
}
});

＆＃13;

<body ng-app="myApp" ng-controller="myCtrl"> 

<my-student></my-student> 
<my-student></my-student> 
<my-student></my-student> 
<my-student></my-student> 
<my-student></my-student> 

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.5/angular.min.js"></script>
</body>

＆＃13;

注意：

请注意，只关注错误和使用指令控制器。我知道同样可以通过预链接，后链接或编译来完成。

我认为它应该是链接功能而不是控制器。

＆＃13;

//module declaration 
var app = angular.module('myApp', []);

//controller declaration
app.controller('myCtrl', function($scope) {
  $scope.name = "Peter";
});

//app declaration
app.directive('myStudent', function() {
  return {
    template: "Hi! Dear!! {{name}}<br/>",
    link: function(scope, elem, attr) {
      console.log("controller");
    }
  }
});

＆＃13;

<body ng-app="myApp" ng-controller="myCtrl">

  <my-student></my-student>
  <my-student></my-student>
  <my-student></my-student>
  <my-student></my-student>
  <my-student></my-student>

  <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.5/angular.min.js"></script>
</body>

最佳实践：当您希望将API公开给其他指令时，请使用控制器。否则使用链接。

Controller接受一个数组：

＆＃13;

var app = angular.module('myApp', []);

//controller declaration
app.controller('myCtrl', function($scope) {
  $scope.name = "Peter";
});

//app declaration
app.directive('myStudent', function() {
  return {
    template: "Hi! Dear!! {{name}}<br/>",
    controller: [
      function(scope, elem, attr) {
        console.log("controller");
      }
    ]
  }
});

＆＃13;

<body ng-app="myApp" ng-controller="myCtrl">

  <my-student></my-student>
  <my-student></my-student>
  <my-student></my-student>
  <my-student></my-student>
  <my-student></my-student>

  <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.5/angular.min.js"></script>
</body>

＆＃13;

如需进一步阅读，我建议angular documentation on directives
