return this.newList = this.list.filter((i) => { return i.name.indexOf(this.inputValue) !== -1;

});This code is written in JavaScript and it filters through an array of objects called "list". The filter function takes in a callback function that checks if an object's "name" property includes the value of "inputValue". If the name includes the input value, it returns true and that object is added to a new array called "newList". The "!== -1" checks if the input value is not found in the name property. If it is not found, it returns false and that object is not added to the new list. Finally, the "newList" array is assigned to "this.newList".

好的，以下是添加搜索框、增删改功能和弹窗编辑功能的代码：

HTML代码：

<h1>通讯录</h1>
<button class="add-btn">添加联系人</button>
<input type="text" id="search-input" placeholder="搜索姓名或电话">
<table>
  <thead>
    <tr>
      <th>姓名</th>
      <th>电话</th>
      <th>邮箱</th>
      <th>操作</th>
    </tr>
  </thead>
  <tbody id="contact-list">
    <!-- 数据渲染 -->
  </tbody>
</table>

<!-- 分页按钮 -->
<div id="page-buttons"></div>

<!-- 弹出层，用于添加或编辑联系人 -->
<div id="modal" class="modal" style="display: none;">
  <div class="modal-content">
    <span class="close">×</span>
    <form>
      <div class="form-group">
        <label for="name">姓名</label>

        <input type="text" id="email" name="email" required>
      </div>
