问题:我使用带有按钮的 md 卡创建了一个网页。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。它的格式不正确并且没有任何功能。
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>

最佳答案
发生这种情况是因为 Angular 不知道这是一个 Angular 组件。你需要用 $compile 包装你的 HTML服务。
- 将“$compile”添加到您的模块依赖项
- 像这样包装代码
$compile('your html here')($scope);
