這篇文章主要介紹了微信小程序之搜索分頁(yè)功能的實(shí)現(xiàn)代碼，本文通過(guò)實(shí)例代碼給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值,需要的朋友可以參考下

直接上代碼：
wxml:

<wxs src="../wxs/changeimg.wxs" module="changeimg" />
<view class="container">
  <view class="search_input">
     <image class="back" src="" mode="widthFix"></image>
     <input type="text" class="weui-input" maxlength="10" placeholder="搜索" value="{{value}}" bindinput="changeModel" bindconfirm="search" data-key="value"/>
 <image class="scan_code" src="" mode="widthFix" ></image>
</view> 
<!--搜索菜品做法列表 -->
<view class="modus_operandi">
<view class="search_no" wx:if="{{searchLen==0&&clickEnter==1}}" >
 <text>很抱歉,沒(méi)有找到您要搜索的資料/(ㄒoㄒ)/~~</text>
</view>
 <view class="modus_operandi_total"
 wx:for="{{searchData}}"
 wx:key="id"
 bindtap="jumpVegetables"
 data-cid="{{item.classid}}"
 >
  <image class="modus_operandi_pic" mode="widthFix" src="{{changeimg.getimageurl(item.defaultpic)}}"></image>
  <view class="modus_operandi_title">{{item.title}}</view>
 </view>
</view>
</view>
