将参数传递给模态

Question

我想将登录用户点击userName的列表传递userName给twitter bootstrap modal.我正在使用带有angularjs的grails,其中数据通过angularjs呈现.

组态

我的grails查看页面encouragement.gsp是

<div ng-controller="EncouragementController">
    <g:render template="encourage/encouragement_modal" />
    <tr ng-cloak
                  ng-repeat="user in result.users">
                   <td>{{user.userName}}</rd>
                   <td>
                      <a class="btn btn-primary span11" href="#encouragementModal" data-toggle="modal">
                            Encourage
                       </a>
                  </td>
                </tr>

我的encourage/_encouragement_modal.gsp是

<div id="encouragementModal" class="modal hide fade">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal"
      aria-hidden="true">&times;</button>
    <h3>Confirm encouragement?</h3>
  </div>
  <div class="modal-body">
      Do you really want to encourage <b>{{aModel.userName}}</b>?
  </div>
  <div class="modal-footer">
    <button class="btn btn-info"
      ng-click="encourage('${createLink(uri: '/encourage/')}',{{aModel.userName}})">
      Confirm
    </button>
    <button class="btn" data-dismiss="modal" aria-hidden="true">Never Mind</button>
  </div>
</div>

那么,我该如何传递userName给encouragementModal？

Answer 1

要传递参数,您需要使用resolve并在控制器中注入项目

$scope.Edit = function (Id) {
   var modalInstance = $modal.open({
      templateUrl: '/app/views/admin/addeditphone.html',
      controller: 'EditCtrl',
      resolve: {
         editId: function () {
           return Id;
         }
       }
    });
}

现在,如果您将使用这样:

app.controller('EditCtrl', ['$scope', '$location'
       , function ($scope, $location, editId)

在这种情况下,editId将是未定义的.你需要注入它,像这样:

app.controller('EditCtrl', ['$scope', '$location', 'editId'
     , function ($scope, $location, editId)

现在它会顺利工作,我多次遇到同样的问题,一旦注入,一切都开始工作了!

另一个不起作用.根据文档,这是你应该这样做的方式.

angular.module('plunker', ['ui.bootstrap']);
var ModalDemoCtrl = function ($scope, $modal) {

    var modalInstance = $modal.open({
      templateUrl: 'myModalContent.html',
      controller: ModalInstanceCtrl,
      resolve: {
        test: function () {
          return 'test variable';
        }
      }
    });
};

var ModalInstanceCtrl = function ($scope, $modalInstance, test) {

  $scope.test = test;
};

或者,您可以创建新范围并通过范围选项传递参数

var scope = $rootScope.$new();
 scope.params = {editId: $scope.editId};
    $modal.open({
        scope: scope,
        templateUrl: 'template.html',
        controller: 'Controller',
    });

在你的模态控制器中传入$ scope,你就不需要传入了itemsProvider或者解决了你命名它的东西

modalController = function($scope) {
    console.log($scope.params)
}

Answer 4

您还可以通过添加具有模态实例的新属性并将其传递给模态控制器,轻松地将参数传递给模态控制器.例如:

以下是我想要打开模态视图的点击事件.

 $scope.openMyModalView = function() {
            var modalInstance = $modal.open({
                    templateUrl: 'app/userDetailView.html',
                    controller: 'UserDetailCtrl as userDetail'
                });
                // add your parameter with modal instance
                modalInstance.userName = 'xyz';
        };

模态控制器:

angular.module('myApp').controller('UserDetailCtrl', ['$modalInstance',
                function ($modalInstance) {
                    // get your parameter from modal instance
                    var currentUser = $modalInstance.userName;
                    // do your work...
                }]);

Answer 5

我尝试如下.

我ng-click在Encourage按钮上调用了angularjs控制器,

               <tr ng-cloak
                  ng-repeat="user in result.users">
                   <td>{{user.userName}}</rd>
                   <td>
                      <a class="btn btn-primary span11" ng-click="setUsername({{user.userName}})" href="#encouragementModal" data-toggle="modal">
                            Encourage
                       </a>
                  </td>
                </tr>

我设置userName的encouragementModal从angularjs控制器.

    /**
     * Encouragement controller for AngularJS
     * 
     * @param $scope
     * @param $http
     * @param encouragementService
     */
    function EncouragementController($scope, $http, encouragementService) {
      /**
       * set invoice number
       */
      $scope.setUsername = function (username) {
            $scope.userName = username;
      };
     }
    EncouragementController.$inject = [ '$scope', '$http', 'encouragementService' ];

我提供了一个place(userName)来从angularjs控制器获取值encouragementModal.

<div id="encouragementModal" class="modal hide fade">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal"
      aria-hidden="true">&times;</button>
    <h3>Confirm encouragement?</h3>
  </div>
  <div class="modal-body">
      Do you really want to encourage <b>{{userName}}</b>?
  </div>
  <div class="modal-footer">
    <button class="btn btn-info"
      ng-click="encourage('${createLink(uri: '/encourage/')}',{{userName}})">
      Confirm
    </button>
    <button class="btn" data-dismiss="modal" aria-hidden="true">Never Mind</button>
  </div>
</div>

它起作用了,我向自己致敬.

您应该真正使用Angular UI来满足这些需求.检查出来:Angular UI对话框

简而言之,使用Angular UI对话框,您可以使用控件将变量从控制器传递到对话框控制器resolve.这是你的"来自"控制器:

var d = $dialog.dialog({
  backdrop: true,
  keyboard: true,
  backdropClick: true,
  templateUrl:  '<url_of_your_template>',
  controller: 'MyDialogCtrl',
  // Interesting stuff here.
  resolve: {
    username: 'foo'
  }
});

d.open();

在你的对话框控制器中:

angular.module('mymodule')
  .controller('MyDialogCtrl', function ($scope, username) {
  // Here, username is 'foo'
  $scope.username = username;
}

编辑:自新版本的ui对话框以来,解析条目变为:

resolve: { username: function () { return 'foo'; } }
