angularjs - 如何为指令设置动态 Controller ？

Question

谈话很便宜，请先显示我的代码:

HTML:

<div add-icons="IconsCtrl">
</div>

指示:

angular.module('attrDirective',[]).directive('addIcons', function($compile){
return {
    restrict : 'A',
    controller : "IconsCtrl"
    },
    link : function (scope, elem , attrs, ctrl) {
        var parentElem = $(elem);
        var icons = $compile("<i class='icon-plus' ng-click='add()'></i>)(scope);
        parentElem.find(".accordion-heading").append(icons);
    },
}

});

Controller :

function IconsCtrl($scope){
  $scope.add = function(){
    console.log("add");
  };
}

现在工作了，当我单击加号图标时，浏览器控制台输出“添加”。

但我想将 Controller 动态设置为指令，如下所示:

HTML:

<div add-icons="IconsOneCtrl">
</div>
<div add-icons="IconsTwoCtrl">
</div>

Controller :

function IconsOneCtrl($scope){
       $scope.add = function(){
        console.log("IconsOne add");
       };
    }

function IconsTwoCtrl($scope){
    $scope.add = function(){
        console.log("IconsTwo add");
    }
}

指令喜欢:

angular.module('attrDirective',[]).directive('addIcons', function($compile){
return {
    restrict : 'A',
    controller : dynamic set,depends on attrs.addIcons
    },
    link : function (scope, elem , attrs, ctrl) {
        var parentElem = $(elem);
        var icons = $compile("<i class='icon-plus' ng-click='add()'></i>)(scope);
        parentElem.find(".accordion-heading").append(icons);
    },
}
});

如何实现我的目标？感谢您的回答!

现在可以使用AngularJS。在指令中，您只需添加两个新属性，即
此处确实需要controller，name属性以及isolate scope。

指令中要注意的重要事项

scope:{}, //isolate scope
controller : "@", // @ symbol
name:"controllerName", // controller names property points to controller.

Working Demo for Setting Dynamic controller for Directives

HTML标记:

<communicator controller-name="PhoneCtrl" ></communicator>
<communicator controller-name="LandlineCtrl" ></communicator>

Angular Controller 和指令:

var app = angular.module('myApp',[]).
directive('communicator', function(){
return {
    restrict : 'E',
    scope:{},
    controller : "@",
    name:"controllerName", 
    template:"<input type='text' ng-model='message'/><input type='button' value='Send Message' ng-click='sendMsg()'><br/>"          
  }   
}).
controller("PhoneCtrl",function($scope){
 $scope.sendMsg = function(){
     alert( $scope.message + " : sending message via Phone Ctrl");
    }
}).
controller("LandlineCtrl",function($scope){
    $scope.sendMsg = function(){
        alert( $scope.message + " : sending message via Land Line Ctrl ");
    }
})

您的情况下，您可以在代码段下面尝试此方法。

Working Demo

HTML标记:

<div add-icons controller-name="IconsOneCtrl">
</div>
<div add-icons controller-name="IconsTwoCtrl">
</div>

Angular 代码:

angular.module('myApp',[]).

directive('addIcons', function(){
return {
    restrict : 'A',
    scope:{},
    controller : "@",
    name:"controllerName",    
    template:'<input type="button" value="(+) plus" ng-click="add()">'
  }
}).
controller("IconsOneCtrl",function($scope){
     $scope.add = function(){
        alert("IconsOne add ");
      }
}).
controller("IconsTwoCtrl",function($scope){
     $scope.add = function(){
        alert("IconsTwo add ");
      }
});
