问题：我创建了一个带有按钮的 md 卡的网页。单击该按钮后，我希望出现另一张卡片。问题：我不知道如何使新卡的按钮起作用。它的格式不正确，没有任何功能。

问题：我需要将代码更改为什么才能使其正常工作？谢谢。

代码：这是我的 JavaScript 代码：

angular.module('MyApp', ['ngMaterial', 'ngMessages', 'material.svgAssetsCache'])
    .controller('AppCtrl', function($scope, $mdDialog) {

    function addMeinElement () { 
                                // create a new div element 
                                var newDiv = document.createElement("md-card");
                                document.querySelector('#myID').appendChild(newDiv);
                                newDiv.innerHTML = "<md-card-content>Oh no! Why does this button not work?<br>"+
                                                    "<md-button class='md-warn' ng-click='my_print_to_console()'>Button :( </md-button>"+
                                                    "</md-card-content>";
                                }

    $scope.my_print_to_console = function ()    {
                                                addMeinElement ();
                                                };  


});

这是对应的html：

                        <p>Click the button to hopefully create a new card with another button.</p>
                            <md-button class="md-warn" ng-click="my_print_to_console()";>Button :)</md-button>
                    </md-card-content>
                </md-card>
                <div id="myID">
                </div>
            </div>
        </div>
    </div>

发生这种情况是因为 Angular 不知道这是一个 Angular 组件。您需要使用$compile服务包装您的 HTML。

  1. 将“$compile”添加到您的模块依赖项中
  2. 像这样包装代码

$compile('你的 html 在这里')($scope);
