我有这样的纸标签
<paper-dialog id="view">
<paper-tabs selected="0">
<paper-tab on-tap="_changeList">TAB 1</paper-tab>
<paper-tab on-tap="_changeList">TAB 2</paper-tab>
<paper-tab on-tap="_changeList">TAB 3</paper-tab>
</paper-tabs>
<iron-list>some story for tab 1</iron-list>
<iron-list>some story for tab 2</iron-list>
<iron-list>some story for tab 3</iron-list>
</paper-dialog>
每个标签我都有不同的熨斗列表。将选择第一个选项卡,但由于用户将单击其他选项卡,因此应更改所选选项卡的内容。_changeList 函数会带来不同的数据。我该如何实现呢?请
