如何为Polymer 1.0执行on-close或dismiss的函数？

题：

How do I automatically execute a function whenever my <paper-dialog> element is closed?

版本：聚合物1.0

码：

<paper-dialog id="paper-id"
              entry-animation="scale-up-animation"
              exit-animation="scale-down-animation">
    <sample-element></sample-element>
</paper-dialog>

解决方法

paper-dialog继承了polymer.IronOverlayBehavior,它具有iron-overlay-opened和iron-overlay-closed事件.

<paper-dialog
  on-iron-overlay-opened="_myOpenFunction"
  on-iron-overlay-closed="_myClosedFunction"></paper-dialog>
