我可以将服务注入 AngularJS 中的指令吗? [英] Can I inject a service into a directive in AngularJS?

问题描述

我正在尝试将服务注入如下指令:

I am trying to inject a service into a directive like below:

 var app = angular.module('app',[]);
 app.factory('myData', function(){
     return {
        name : "myName"
     }
 });
 app.directive('changeIt',function($compile, myData){
    return {
            restrict: 'C',
            link: function (scope, element, attrs) {
                scope.name = myData.name;
            }
        }
 });

但这给我返回了一个错误Unknown provider: myDataProvider.有人可以查看代码并告诉我我做错了什么吗?

But this is returning me an error Unknown provider: myDataProvider. Could someone please look into the code and tell me if I am doing something wrong?

推荐答案

你可以对指令进行注入，它看起来就像在其他地方一样.

You can do injection on Directives, and it looks just like it does everywhere else.

app.directive('changeIt', ['myData', function(myData){
    return {
        restrict: 'C',
        link: function (scope, element, attrs) {
            scope.name = myData.name;
        }
    }
 }]);
