如何注入鏈接函數包含指令的服務？

Question

我正在嘗試將服務注入下面的使用鏈接函數而不是控制器的指令。

(function() { 
angular 
.module("myApp") 
.directive('myDirective',['$scope','myService','myData',function($scope,myService,myData) { 
return { 
    restrict'AE', 
    replace:'true', 
    templateUrl :'/myApp/directive/my-directive', 
    scope: { 
     userId: "@" 
     } 
    }, 
    link:function(scope,elem,attr) 
     { 
     //Code for link function goes here ... 
      scope.myUsersArray []; 
      scope.getUserDetails = function() 
       { 
       //code for getUserdetails goes here... 
       } 

     } 
    }]); 
    })(); 

當我運行這段代碼，我得到像例外[$注射器：unpr]未知提供商< _ $範圍錯誤。如果我刪除注入的服務，我沒有收到任何錯誤。錯誤拋出的angular.js文件，所以我沒有任何線索來解決它:(

你有幾個語法問題，你的代碼應該是這樣的：

.directive('myDirective', ['$scope', 'myService', 'myData', function($scope, myService, myData) { 
    return { 
     restrict: 'AE', 
     replace: 'true', 
     templateUrl: '/myApp/directive/my-directive', 
     scope: { 
     userId: "@" 
     }, 
     link: function(scope, elem, attr) { 
     //Code for link function goes here ... 
     scope.myUsersArray = []; 
     scope.getUserDetails = function() { 
      //code for getUserdetails goes here... 
     }; 
     } 
    }; 
    }]); 

您可能會遇到問題多爲它不明顯爲什麼你注入$ scope，myService和myData
