如何使用纸质对话聚合物元件? [英] How to use paper-dialog polymer element?

问题描述

我正在通过添加开始和结束标签<paper-dialog><p>This is it</p></paper-dialog>使用元素，但是没有显示出来.我是否需要在脚本之上添加一些脚本，以便在某些事件上触发该脚本?还是有其他方法使其可见?

I am using the element by adding opening and closing tags <paper-dialog><p>This is it</p></paper-dialog> but it is not getting shown up. Do I need to add some script on top of it so that it should be triggered on some event? Or is there some another way to make it visible ?

推荐答案

对话框本身是自动隐藏的.通常，您可以使用按钮进行切换. 例如，给对话框一个id="dialog"并将按钮on-tap="toggleDialog"设置为

The dialog itself is autohidden. You usually toggle it with a button. For example, give the dialog an id="dialog" and make the button on-tap="toggleDialog" , which would be

toggleDialog: () => {
    this.$.dialog.toggle();
},
