angular.js - angular filter问题

Question

下面是angular官网上讲解filter的代码，有些地方没看懂，辛苦各位大神赐教了。

<p ng-init="friends = [{name:'John', phone:'555-1276'},
                         {name:'Mary', phone:'800-BIG-MARY'},
                         {name:'Mike', phone:'555-4321'},
                         {name:'Adam', phone:'555-5678'},
                         {name:'Julie', phone:'555-8765'},
                         {name:'Juliette', phone:'555-5678'}]"></p>

Search: <input ng-model="searchText">
<table id="searchTextResults">
  <tr><th>Name</th><th>Phone</th></tr>
  <tr ng-repeat="friend in friends | filter:searchText">
    <td>{{friend.name}}</td>
    <td>{{friend.phone}}</td>
  </tr>
</table>
<hr>
Any: <input ng-model="search.$"> <br>
Name only <input ng-model="search.name"><br>
Phone only <input ng-model="search.phone"><br>
Equality <input type="checkbox" ng-model="strict"><br>
<table id="searchObjResults">
  <tr><th>Name</th><th>Phone</th></tr>
  <tr ng-repeat="friendObj in friends | filter:search:strict">
    <td>{{friendObj.name}}</td>
    <td>{{friendObj.phone}}</td>
  </tr>
</table>

界面显示效果：

当勾选Equality时，下面的内容不会显示出来

代码中对应的是

不明白它的filter:search:strict是怎么起作用的？为什么什么都不能显示了？

Answer 1

The check box is useful. When checked, it is true, which means strict comparison, which means that you have to enter exactly the same thing to filter it out. You can try to enter John in Name only and it will filter out.
