1、WXML文件

<!--搜索框 -->
<view class="weui-search-bar">
 <view class="weui-search-bar\_\_form">
 <!--点击之后，出现input框 -->
 <view class="weui-search-bar\_\_box">
  <icon class="weui-icon-search\_in-box" type="search" size="14"></icon>
  <input type="text" class="weui-search-bar\_\_input" placeholder="搜索" value="{{inputVal}}" focus="{{inputShowed}}" bindinput="inputTyping" />
  <!--输入款字数大于0，则显示清除按钮 -->
  <view class="weui-icon-clear" wx:if="{{inputVal.length > 0}}" bindtap="clearInput">
  <icon type="clear" size="14"></icon>
  </view>
 </view>
 <!--没点击之前，只是一些文字和图标 -->
 <label class="weui-search-bar\_\_label" hidden="{{inputShowed}}" bindtap="showInput">
  <icon class="weui-icon-search" type="search" size="14"></icon>
  <view class="weui-search-bar\_\_text">搜索</view>
 </label>
 </view>
 <!--动态出现的“取消”键 -->
 <view class="weui-search-bar\_\_cancel-btn" hidden="{{!inputShowed}}" bindtap="hideInput">取消</view>
</view>
