uni-app实现的搜索功能 可以应用到vue 小程序

把搜索的输入框写成了一个组件

父组件直接引用即可

废话不说上代码  搜索框组件

 search.vue 

<template>
	<view class="search" :style="{ backgroundColor: backgroundColor }">

				<!-- <view v-if="!active && mode === 2" class="input sub" @click="getFocus">请输入搜索内容</view> -->

引用 搜索框

Quotesearch.vue

<template>
	<view>
      =============================
    使用
		<mSearch :show="false" @search="search($event, 1)"></mSearch>
      ==================================
下面是我写的一些别的 可以不用看

		<view class="hot-search-wrap" v-if="isShowHotKey">
			<view class="hot-search"><text class="shugang"></text> <text class="textinfo">热门搜索</text> </view>
