使用Angular JS创建简单的弹出窗口

angularjspopup
15

我是AngularJS的新手。我有4个按钮，名为Cancel、Deny、Success和Remove。如果我点击任何一个按钮，我希望显示多个消息，即如果我点击取消，则显示消息“您单击了取消按钮”，以此类推。

我已经从下面的链接中进行了尝试，但是该示例仅使用了简单的警报，没有使用控制器。

我想要一个在AngularJS指令中使用模态弹出窗口的示例，这样我就可以理解了。我已经尝试谷歌搜索，但没有找到简单的示例。

请帮忙。谢谢。

你是指 Angular Model 吗？ - Ved
我想要一个简单的例子，比如一个包含HTML数据的HTML文件和其他包含弹出数据的文件。通过点击这些按钮，多个消息会在弹出窗口中显示。 - veera
感谢 @syarul。HTML 文件名我想是 index.html，但 JS 文件名是什么呢？ - veera
你不需要加载Bootstrap，移除类和CSS链接。 - syarul
在你的jsfiddle中，我已经删除了bootstrap.min.css和bootstrap.min.js，然后它就无法工作了，请您更新一下jsfiddle。 - veera

使用Syarul的jsFiddle链接构建了一个模态弹出窗口示例。这是更新的fiddle。

创建了一个名为modal的Angular指令，并在HTML中使用。

说明：

HTML

<div ng-controller="MainCtrl" class="container">
  <button ng-click="toggleModal('Success')" class="btn btn-default">Success</button>
  <button ng-click="toggleModal('Remove')" class="btn btn-default">Remove</button>
  <button ng-click="toggleModal('Deny')" class="btn btn-default">Deny</button>
  <button ng-click="toggleModal('Cancel')" class="btn btn-default">Cancel</button>
  <modal visible="showModal">
      Any additional data / buttons
  </modal>
</div>

JS

var mymodal = angular.module('mymodal', []);

mymodal.controller('MainCtrl', function ($scope) {
    $scope.showModal = false;
    $scope.buttonClicked = "";
    $scope.toggleModal = function(btnClicked){
        $scope.buttonClicked = btnClicked;
        $scope.showModal = !$scope.showModal;
    };
  });

mymodal.directive('modal', function () {
    return {
      template: '<div class="modal fade">' + 
          '<div class="modal-dialog">' + 
            '<div class="modal-content">' + 
              '<div class="modal-header">' + 
                '<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>' + 
                '<h4 class="modal-title">{{ buttonClicked }} clicked!!</h4>' + 
              '</div>' + 
              '<div class="modal-body" ng-transclude></div>' + 
            '</div>' + 
          '</div>' + 
        '</div>',
      restrict: 'E',
      transclude: true,
      replace:true,
      scope:true,
      link: function postLink(scope, element, attrs) {
        scope.title = attrs.title;

        scope.$watch(attrs.visible, function(value){
          if(value == true)
            $(element).modal('show');
          else
            $(element).modal('hide');
        });

        $(element).on('shown.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = true;
          });
        });

        $(element).on('hidden.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = false;
          });
        });
      }
    };
  });

更新2 restrict : 'E' : 指令用于作为HTML标签（元素）使用。在我们的案例中，示例为

<modal>

其他的值是 'A' ，代表属性。

<div modal>

'C'代表类（在我们的情况下不建议使用，因为modal已经是bootstrap.css中的一个类）


<div class="modal">
你有没有遇到任何控制台错误？你还需要jQuery。 - Aman Dhanjal
没有错误，当我点击按钮时所有按钮都显示，没有弹出窗口。 - veera
你忘记引入angular.js，而是将bootstrap作为脚本添加了。请查看我更新的帖子以获取您的已更正代码。 - Aman Dhanjal
我刚刚添加了"<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.min.js"></script>"，但是没有点击输出。我认为CSS没有调用。 - veera
已更新答案 :) - Aman Dhanjal

如果您正在使用bootstrap.js，则下面的代码可能非常有用。这很简单，不需要编写任何js来调用弹出窗口。

这是在Angular JS中展示Bootstrap 5模态框的最简单方法

var app = angular.module('myApp', [])
    .controller('myCtrl', function ($scope) {
        $scope.title = "Bootstrap Modal From HTML & Java Script(Code Behind)"
        $scope.openModal = function () {
            $('#exampleModal').modal('show');
        }
    });
