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

체크박스를 선택하면 true입니다. 이는 엄격한 비교를 의미합니다. 즉, 이름에만 John을 입력하면 필터링됩니다.
