javascript - 更改在单击数据绑定(bind)时显示的纸张选项卡- polymer

我想动态地更改选择侧栏上的按钮时在页面中显示的纸张选项卡。

即。 （选择|要显示的标签）

专家| 3个标签

管理员| 4个标签

等等

当我针对滚动对话框中显示的数据选择选项卡本身时，已经设法使数据绑定起作用，我只是停留在此上。

page-tabs.html

<!-- THIS IS STILL A PRETTY BASIC EXAMPLE -->
<paper-tabs selected="{{selected}}" noink>
   <paper-tab link>
      <a href="#tab1" tabindex="-1">TAB 1</a>
    </paper-tab>
    <paper-tab link>
      <a href="#tab2" tabindex="-1">TAB 2</a>
    </paper-tab>
    <paper-tab link>
      <a href="#tab3" tabindex="-1">TAB 3</a>
    </paper-tab>
</paper-tabs>

<iron-pages selected="{{selected}}">
    <div>CONTENT OF PAGE 1</div>
    <div>CONTENT OF PAGE 2</div>
    <div>CONTENT OF PAGE 3</div>
</iron-pages>

        <iron-icon icon="supervisor-account" slot="item-icon"></iron-icon> <span>Admin</span>
      </paper-icon-item>
      <div class="flex"></div> <!-- THIS IS THE ONLY WAY THAT I COULD GET THE LAST ENTRY TO BE FLEXED TO THE BOTTOM -->
      <paper-icon-item on-click="{{settingsPage}}">
        <iron-icon icon="settings" slot="item-icon"></iron-icon> <span id="">Settings</span>
      </paper-icon-item>

    </div>

最佳答案

您可以使用<iron-pages>管理标签页，例如

<iron-pages selected="[[page]]">
    <!-- Expert | 3 tabs -->
    <page-tabs-expert></page-tabs-expert>
    <!--- Admin | 4 tabs -->
    <page-tabs-admin></page-tabs-admin>
    <!-- etc. -->
    <page-tabs-etc></page-tabs-etc>
</iron-pages>

并且，通过<iron-selector>，https://www.webcomponents.org/element/PolymerElements/iron-selector使边栏变为可选择状态

<iron-selector selected={{page}}>
