  <p ng-bind="age"></p>
</div>
<h3>ng-init初始化对象</h3>
<div ng-init="hero={name:'aurora',role:'sup',line:'不管刮风还是下雨，太阳照常升起'}">

</div>
 
<h3>ng-controller控制器</h3>
<div ng-controller="contr-2">
  First Name: <input type="text" ng-model="firstName">
  Last Name: <input type="text" ng-model="lastName">
  Full Name : <span>{{firstName + "," + lastName}}</span>
  Full Name : <span ng-bind="firstName + ',' + lastName"></span>  
</div>
 
<h3>ng-repeat遍历无重复集合</h3>
<div ng-init="names=[1,2,3]">
 <ul>
  <li ng-repeat="x in names">
   {{x}}
  </li>
 </ul>
</div>
<h3>ng-repeat遍历重复集合</h3>
<div ng-init="number=[1,2,2,3]">
 <ul>
  <li ng-repeat="x in number track by $index">
   {{x}}
  </li>
 </ul>
</div>
<h3>ng-repeat遍历对象</h3>
<div ng-controller="contr-3">
   <ul>
    <li ng-repeat="(key,value) in object track by $index">
     {{key+":"+value}}
    </li>
   </ul>
</div>
<h3>ng-repeat遍历对象(按原有顺序)</h3>
<div ng-controller="contr-4">
   <ul ng-repeat="obj in objs ">
    <li ng-repeat="(key,value) in obj ">
     {{key+":"+value}}
    </li>
   </ul>
</div>
<h3>ng-repeat遍历对象(属性详解)</h3>
<table ng-controller="contr-5">
  <tr ng-repeat="(key, value) in objs ">
    <td>学号:
      <span ng-bind="$index"></span>
    </td>
    <td>
      <span ng-bind="key"></span>:
      <span ng-bind="value"></span>
    </td>
    <td>是否为奇数？
      <span ng-bind="$odd"></span>
    </td>
    <td>是否为偶数？
      <span ng-bind="$even"></span>
    </td>
    <td>排行是老大？
      <span ng-bind="$first"></span>
    </td>
    <td>排行最小？
      <span ng-bind="$last"></span>
    </td>
    <td>排行中间？
      <span ng-bind="$middle"></span>
    </td>
  </tr>
</table>
<h3>ng-repeat start/end</h3>
<div ng-controller="contr-6">
  <div ng-repeat-start="(key,value) in objs">
    <p>学号:
      <span ng-bind="$index"></span>
    </p>
    <p>
      <span ng-bind="key"></span>:
      <span ng-bind="value"></span>
    </p>
  </div>
