如何为聚合物1.0执行on-close或关闭<paper-dialog>的功能？

Question

题:

每当<paper-dialog>元素关闭时如何自动执行函数？

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>

Answer 1

paper-dialog继承了Polymer.IronOverlayBehavior,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>
