javascript - 更改单击数据绑定(bind)时显示的纸张选项卡 - Polymer

Question

我想在选择侧边栏上的按钮时动态更改页面中显示的纸张选项卡。

即。 (选择|要显示的选项卡)

专家 | 3 个标签

管理员 | 4 个标签

等等

当我选择与可滚动对话框中显示的数据相关的选项卡本身时，我已经成功地使数据绑定(bind)工作，但我只是停留在这一点上。

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>

      <paper-icon-item on-click="{{adminPage}}">
        <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>

感谢任何帮助。

您可以使用 <iron-pages> 管理您的标签页，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，让你的侧边栏可以选择 <iron-selector> , https://www.webcomponents.org/element/PolymerElements/iron-selector

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