使用聚合物将纸张标签绑定到核心页面

Question

使用聚合物将纸张标签绑定到核心页面

我正在使用Polymer构建一个使用纸质标签和核心页面的网站.我遇到的问题是,我似乎无法让标签的click事件影响正在显示的页面,并且所有内容都保持隐藏状态,除非我专门选择我想要显示的页面.
所以我真的只是想让标签表现出标签应该表现的方式.

到目前为止,这是我的代码:

<body unresolved>

  <paper-tabs selected="0" selectedindex="0"  id="paper-tabs"  >

    <paper-tab id="paper-tab" active>ABOUT</paper-tab>
    <paper-tab id="paper-tab1">PORTFOLIO</paper-tab>
    <paper-tab id="paper-tab2">CONTACT</paper-tab>

  </paper-tabs>



  <core-pages selected="{{$.paper-tab.selected}} " selectedindex="0" notap  id="core-pages">
    <about-me id="paper-tab" active>
      <h2 horizontal center-justified>Worldwide Jamie</h2>
      <p>Jamie is a Chicago-based freelance front end web developer.</p>
      <p>Clearly this website is <b>Under Development</b></p>
      <p>Come back soon to see how great your site could be</p>
    </about-me>

    <portfolio-list id="portfolio">
    <!--Insert slider?-->
    </portfolio-list>

    <contact-me id="contact">
    </contact-me>
  </core-pages>    

    </body>
</html>

从Polymer 1.0+开始,这就是你想要使用的东西.

<link rel="import" href="components/paper-tabs/paper-tabs.html">
<link rel="import" href="components/iron-pages/iron-pages.html">

<paper-tabs selected="0">
    <paper-tab>Tab One</paper-tab>
    <paper-tab>Tab Two</paper-tab>
</paper-tabs>

<iron-pages selected="0">
    <div>Page One</div>
    <div>Page Two</div>
</iron-pages>

<script>
     var pages = document.querySelector('iron-pages');
     var tabs = document.querySelector('paper-tabs');

    tabs.addEventListener('iron-select', function() { 
        pages.selected = tabs.selected;
    });
</script>

简单.在脚本中使用它.

var tabs = document.querySelector('paper-tabs');
var pages = document.querySelector('core-pages');

tabs.addEventListener('core-select',function(){
  pages.selected = tabs.selected;
});
