本文介绍了如何转移$ scope.variables到控制器?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我建立了一个系统,我有一个清单,列出变量项


  1. 标题

  2. 技能

  3. 预算

  4. 发布

我也有,当我在列表中的项目点击打开一个模式。我想借当前选定的项目,并在我的第二个模式的控制器使用其变量?这可能吗?

我在思维模式的使用,其中i缓存从数据库中抽取的所有数据服务的,但后来我不知道我怎么会只显示选定的项目,而不是每一个项目。

下面是我的控制器列表项:

  app.controller('openProjectsCtrl',['$范围,$ HTTP,projectsModal',
功能($范围,$ HTTP,projectsModal){  $ http.get(HTTP://localhost/app/controllers/php/getProjects.php)
  .success(功能(响应){
    $ scope.projects = response.projects;
  });  $ scope.showModal =功能(){
      projectsModal.deactivate();
      projectsModal.activate();
  };}]);

模态控制器(我想要查看选定变量):

  app.controller('projectsModalCtrl',['$范围,$超时','projectsModal',
功能($范围,$超时,projectsModal){VAR CTRL =这一点;ctrl.closeMe =功能(){
  projectsModal.deactivate();
};}]);


解决方案

是的,你可以使用一个控制器的变量使用两种方法的另一个控制器里面


  1. 创建服务之间的通信。

  2. 使用$ rootScope。$广播

样code

  angular.module('为MyService,[])。服务('msgBus',函数(){
        this.serviceValue = {};    }]);
});

和使用它的控制器是这样的:

控制器1

  angular.module('为MyService,[])。控制器(CTRL1',函数($范围,msgBus){
    $ scope.sendmsg =功能(){
        msgBus.serviceValue =你好;
   }
});

控制器2

  angular.module('为MyService,[])。控制器('CTRL2',函数($范围,msgBus){
$ scope.checkValue(){
警报(msgBus.serviceValue);
}
});

I am building a system where i have items listed in a list with variables

I also have a Modal that opens up when i click on an item in the list. I would like to take the current selected item and use its variables in my second modal controller? Is this possible?

I was thinking of using a service where i cache all data that is pulled from database, but then i dont know how i would only display selected item and not EVERY item in the modal.

Here is my controller for the list items:

app.controller('openProjectsCtrl', ['$scope', '$http', 'projectsModal',
function ($scope, $http, projectsModal) {

  $http.get("http://localhost/app/controllers/php/getProjects.php")
  .success(function (response) {
    $scope.projects = response.projects;
  });

  $scope.showModal = function() {
      projectsModal.deactivate();
      projectsModal.activate();
  };    

}]);

Modal Controller(Where i want to view the Selected Variables):

app.controller('projectsModalCtrl', ['$scope', '$timeout', 'projectsModal',
function ($scope, $timeout, projectsModal) {

var ctrl = this;

ctrl.closeMe = function () {
  projectsModal.deactivate();
};

}]);

解决方案

Yes you can use variables of one controller inside another controller using two methods

  1. Create Service to communicate between them.
  2. Use $rootScope.$broadcast

sample code

angular.module('myservice', []).service('msgBus', function() {
        this.serviceValue= {};

    }]);
});

and use it in controller like this:

controller 1

angular.module('myservice', []).controller('ctrl1',function($scope, msgBus) {
    $scope.sendmsg = function() {
        msgBus.serviceValue='Hello'; 
   }
});

controller 2

angular.module('myservice', []).controller('ctrl2',function($scope, msgBus) {
$scope.checkValue(){   
alert( msgBus.serviceValue);
}
});
