module.dialog('prompt',function(dependencies){
    return {
        templateUrl:'prompt.html',controller:function($scope){},something:'value'
    }
});@H_301_4@ 
 
我还希望能够在控制器中使用已注册的对话框(依赖注入)
 
  
 
module.controller('ListCtrl',function($scope,prompt){
    $scope.deleteItem = function(item){
        prompt('Do you want to delete this item?').then(function(result){
            if(result) item.$delete();
        });
    }
});@H_301_4@ 
 
这归结为以下问题：
 
 
>如何扩展angular的模块以使module.dialog注册我的对话框类型？
>如何将注册的对话框注入控制器等？
 
 
顺便说一句,
 
 
>我知道angular-ui和angular-strap.
>我宁愿不使用对话框作为服务,而是作为一个单独的类型(此解决方案已经在angular-ui中实现).

这是一个非常有趣的问题.我将在答案前加上一个观点：我认为你不应该扩展angular.module来提供一个对话方法.这些方法是内置Angular提供程序的快捷方式,Angular团队不时添加一些方法.既然你可以在不添加对话方法的情况下访问你正在寻找的功能,我就不会.也就是说,下面的代码确实向您展示了它的基本版本如何工作(它不会修改Angular模块原型,只修改模块的单个实例).

<div ng-app="myApp">
  <div ng-controller='MainController'>
    <div>
      <button ng-click='askName()'>Ask Name</button>
      <button ng-click='askNameAgain()'>Ask Name Again</button>
      <button ng-click='askAge()'>Ask Age</button>
      <button ng-click='askFood()'>Ask Food</button>
    </div>
    <div>{{lastResponse}}</div>
  </div>
</div>@H_301_4@ 
 
var app = angular.module('myApp',[]);

// Provide some basic injectables for testing
app.constant('nameString','NAME');
app.constant('ageString','AGE');
app.constant('foodString','FAVORITE FOOD');

// Create the dialog provider
app.provider('dialog',function($provide,$injector) {
  var dialogs = {};

  this.register = function(name,configFn) {
    // Create a new service
    $provide.factory(name,function($window,$q) {
      dialogs[name] = function() {
        // Get data based on DI injected version of configFn
        var data = $injector.invoke(configFn);
        // faking async here since prompt is really synchronous
        var deferred = $q.defer();
        var response = $window.prompt(data.text);
        deferred.resolve(response);
        return deferred.promise;
      };
      return dialogs[name];
    });
  };

  // Injecting the service itself gives you a function that
  // allows you to access a dialog by name,much like $filter
  this.$get = function() {
    return function(name) {
      return dialogs[name];
    };
  };
});

// Providing dialog injectables via app.config
app.config(function(dialogProvider) {
  dialogProvider.register('askFood',function(foodString) {
    return { text: 'What is your ' + foodString + '?' }
  });
});

// Alternatively,shortcut to accessing the dialogProvider via app.dialog
app.dialog = function(name,configFn) {
  app.config(function(dialogProvider) {
    dialogProvider.register(name,configFn);
  });
};

app.dialog('askName',function(nameString) {
  return { text: 'What is your ' + nameString + '?' }
});

app.dialog('askAge',function(ageString) {
  return { text: 'What is your ' + ageString + '?' }
});

app.controller('MainController',askName,askAge,askFood,dialog) {
  var setLastResponse = function(result) {
    $scope.lastResponse = result;
  };

  $scope.askName = function() {
    askName().then(setLastResponse);
  };

  $scope.askNameAgain = function() {
    // get the dialog through the dialog service
    // much like how $filter works
    var theDialog = dialog('askName');
    theDialog().then(setLastResponse);
  };

  $scope.askAge = function() {
    askAge().then(setLastResponse);
  };

  $scope.askFood = function() {
    askFood().then(setLastResponse);
  };
});@H_301_4@

通过利用dialogProvider.register函数中的$injector.invoke,您可以在configFn返回的数据中使用类似控制器的键.由于指令已经很像这样,你可以通过查看the AngularJS source获得很多.
