AngularJS：如何调用函数的服务？ [英] AngularJS : how to call function in service?

问题描述

我要AngularJS更改路径没有重新加载，
我的用户的情况是更改包含一些ID的URL，这样用户可以共享/发送该URL给朋友。
我看了<一个href=\"http://stackoverflow.com/questions/23585065/angularjs-ui-router-change-url-without-reloading-state\">AngularJS UI路由器 - 变更网址无需重新加载状态

I want to AngularJS Change Path Without Reloading, my user case is to change URL that contain the some id, so user can share/send this url to friends. I looked AngularJS UI Router - change url without reloading state

在core.js：

'use strict';
angular.module('App', ['ngRoute'])
  .service('$locationEx', ['$location', '$route', '$rootScope',
    function($location, $route, $rootScope) {
      $location.skipReload = function() {
        var lastRoute = $route.current;
        var un = $rootScope.$on('$locationChangeSuccess', function() {
          $route.current = lastRoute;
          un();
        });
        return $location;
      };
      return $location;
    }
  ]);

在控制器：

angular.module('App')
  .controller('DetailController', ['$scope', '$locationEx',
      function($scope, $locationEx) {
        $scope.changeURL = function() {
          console.log("IN changeURL");
          $locationEx.skipReload().path("sdfasdfasdfsadf").replace();
        };

如果调用changeURL，就会发生错误：类型错误：$ locationEx.ski preLOAD不是一个函数

If invoke changeURL, it will occur error:TypeError: $locationEx.skipReload is not a function

有人可以帮我吗？谢谢！

Can somebody help me? Thanks!

推荐答案

我相信你必须使用一个服务'这个'分配服务中的属性时。因此，而不是你的服务看起来像：

I believe for a service you have to use 'this' when assigning properties within the service. So instead your service would look like:

'use strict';
angular.module('App', ['ngRoute'])
  .service('$locationEx', ['$route', '$rootScope',
    function($route, $rootScope) {
      this.skipReload = function() {
        var lastRoute = $route.current;
        var un = $rootScope.$on('$locationChangeSuccess', function() {
          $route.current = lastRoute;
          un();
        });
      };
    }
  ]);

看起来不像你所需要的位置$服务，但我可能是误会根据您如何措辞的问题。

Doesn't look like you need the $location service but I might be misunderstanding based on how you've phrased the question.
