vue 検索フィルタ

本論文の例では、Vueの検索フィルタリング効果を実現するための具体的なコードを共有します。
html数:


<table id="tfhover_1" class="tftable_1" border="1">
  <tr>
    <th>  </th>
    <th>    </th>
    <th>IP</th>
    <th>    </th>
    <th>    </th>
    <th>    </th>
  </tr>
  <tr v-cloak v-for="(item, index) of slist">
    <td>{{item.name}}</td>
    <td>{{item.username}}</td>
    <td>{{item.email}}</td>
    <td>{{item.sex}}</td>
    <td>{{item.province}}</td>
    <td>{{item.hobb}}</td>
    <!--<td><a href="javascript:;" rel="external nofollow" rel="external nofollow" @click="showOverlay(index)">  </a> | <a href="javascript:;" rel="external nofollow" rel="external nofollow" @click="del(index)">  </a></td>-->
  </tr>
