使用dart angular2中的组件中的纸标签 [英] using paper-tabs in a component in dart angular2
问题描述
我试图在dart angular2组件中使用聚合物纸标签，但无法。我在下面的代码中缺少什么？
I'm trying to utilize polymer paper-tabs in a dart angular2 component, but am unable. What am I missing in the code below?
在下面的代码中，在index.html模板中指定的论文选项卡工作正常，但是main-app.html格式不正确，在没有任何正确动画的情况下点击时会消失。
In the following code, the paper-tabs specified in the index.html template work fine, but the paper-tabs in the main-app.html are not formatted correctly and disappear when clicked without any proper animation.

推荐答案
像Polymer一样使用Angular2，启用完整的阴影DOM
As usual when Polymer is used with Angular2 you need to enable full shadow DOM
在其他脚本标记之前添加此标记
Add this before other script tags
<script src="packages/web_components/webcomponents.js"></script>
<script>
/* this script must run before Polymer is imported */
window.Polymer = {
dom: 'shadow',
lazyRegister: true
};
</script>
