完整效果演示
首先完成这个伪搜索框
src/components/search/index.vue （通用搜索框组件）
<template>
<div class="mine-search-box-wrapper">
<i class="iconfont icon-search"></i>
<div class="mine-search-box" v-if="fake">{{placeholder}}</div>
<input
class="mine-search-box"
type="text"
title="搜索框"
:placeholder="placeholder"
ref="input"
v-model="query"
v-if="!fake"
>
<i
class="iconfont icon-close"
v-show="query"
@click="reset"
></i>
</div>
</template>
<script>
import {debounde} from 'assets/js/util';
export default {
name:'search',
props:{//接收的参数
placeholder:{
type:string,
default:'请输入搜索内容'
},
fake:{
type:boolean,
default:false
}
},
data(){
return{
query:'',
}
},
watch:{
query:debounde(function(){
this.$emit('query',this.query);
})
},
methods:{
focus(){
this.$refs.input && this.$refs.input.focus();
},
clear(){
this.query='';
},
reset(){//重置
this.clear();
this.focus();
}
}
}
</script>
<style lang="scss" scoped>
$search-box-height: 30px;
$icon-color: #ccc;
$icon-font-size-sm: 18px;
.mine-search-box-wrapper {
display: flex;
align-items: center;
width: 85%;
height: $search-box-height;
padding: 0 7px;
background-color: #fff;
border-radius: $search-box-height / 2;
margin-left:15px;
}
.iconfont {
color: $icon-color;
font-size: $icon-font-size-sm;
font-weight: bold;
}
.mine-search-box {
flex: 1;
background: none;
border: none;
margin: 0 6px;
color: #666;
line-height: 1.5;
}
</style>
src/assets/js/util.js 节流函数（防止请求数据时频率过快消耗性能）
//函数节流
export const debounde=(func,delay=200)=>{
let timer=null;
return function(...args){
timer && cleartimeout(timer);
timer=settimeout(()=>{
func.apply(this,args);
},delay);
}
}
在分类页的头部组件中引入搜索框组件
src/pages/category/header.vue
<template>
<div class="header">
<i class="iconfont icon-scan header-left"></i>
<div class="header-center">
<search placeholder="开学季有礼，好货五折起" @query='getquery' fake @click.native="gotosearch" />
</div>
<i class="iconfont icon-msg header-right"></i>
</div>
</template>
<script>
import search from 'components/search';
export default {
name:'categoryheader',
components:{
search
},
methods:{
getquery(query){
console.log(query);
},
gotosearch(){
this.$router.push('/search');
}
}
}
</script>
<style lang="scss" scoped>
.header{
background-color:rgba(222, 24, 27, 0.9);
transition:background-color 0.5s;
display: flex;
justify-content: space-between;
align-items: center;
padding:5px 20px;
.iconfont{
font-size:24px;
color:#fff;
}
.header-center{
flex:1;
}
}
</style>
点击搜索框之后会跳转到真正的搜索页
热门搜索组件
src/pages/search/hot.vue
<template>
<div class="hot">
<h4 class="hot-title">热门搜索</h4>
<div class="loading-container" v-if="!hots.length">
<me-loading/>
</div>
<ul class="hot-list" v-else>
<li class="hot-item" v-for="(item,index) in hots" :key="index" @click="$_selectitem(item.hotword)">
{{item.hotword}}
</li>
</ul>
</div>
</template>
<script>
import search from 'components/search';
import meloading from 'components/loading';
import {gethot} from 'api/search';
import {searchmixin} from 'api/mixins';
export default {
name:'searchhot',
components:{
meloading
},
data(){
return{
hots:[]
}
},
mixins:[searchmixin],
created(){
this.gethot().then(()=>{
this.$emit('loaded');
})
},
methods:{
gethot(){
return gethot().then(data=>{
return new promise(resolve=>{
if(data){
this.hots=data;
resolve();
}
})
})
}
}
}
</script>
<style lang="scss" scoped>
$border-color: #e5e5e5;
$font-size-base: 12px;
$font-size-l: $font-size-base + 2;
.hot {
padding-left: 10px;
background-color: #fff;
border-bottom: 1px solid $border-color;
margin-bottom: 10px;
&-title {
height: 34px;
line-height: 34px;
font-size: $font-size-l;
font-weight: bold;
}
&-list {
display: flex;
flex-wrap: wrap;
}
&-item {
padding: 8px;
background-color: #f0f2f5;
border-radius: 4px;
margin: 0 10px 10px 0;
color: #686868;
}
}
.loading-container {
padding: 10px 0;
}
</style>
axios获取热门搜索数据
src/api/search.js
import axios from 'axios';
//获取热门搜索数据 ajax
export const gethot=()=>{
return axios.get('http://www.imooc.com/api/search/hot').then(res=>{
res=res.data.hotkeyword;
if(res && res.owner){
return res.owner;
}
throw new error('没有成功获取到数据');
}).catch(err=>{
console.log(err);
});
}
点击搜索的关键词，跳转到淘宝搜索程序
src/api/mixins.js
import storage from 'assets/js/storage';
import {search_history_keyword_key} from 'pages/search/config';
export const searchmixin={
methods:{
$_selectitem(keyword){
let keywords=storage.get(search_history_keyword_key,[]);//找到所有搜索历史
if(keywords.length!=0){
keywords=keywords.filter(val=>val!=keyword);//这次的关键词如果在搜索历史里已存在，先剔除掉
}
keywords.unshift(keyword);//把这次的关键词放在搜索历史的最开头
storage.set(search_history_keyword_key,keywords);//更新搜索历史
//跳转到淘宝搜索页
location.href = `https://s.m.taobao.com/h5?event_submit_do_new_search_auction=1&_input_charset=utf-8&topsearch=1&atype=b&searchfrom=1&action=home%3aredirect_app_action&from=1&sst=1&n=20&buying=buyitnow&q=${keyword}`;
}
}
}
本地存储文件 assets/js/storage.js
const storage = window.localstorage;
export default {
set(key, val) {
if (val === undefined) {
return;
}
storage.setitem(key, serialize(val));
},
get(key, def) {
const val = deserialize(storage.getitem(key));
return val === undefined ? def : val;
},
remove(key) {
storage.removeitem(key);
},
clear() {
storage.clear();
}
};
function serialize(val) {
return json.stringify(val);
}
function deserialize(val) {
if (typeof val !== 'string') {
return undefined;
}
try {
return json.parse(val);
} catch (e) {
return val || undefined;
}
}
搜索页配置文件 src/pages/search/config.js
const prefix = 'mall-search';
const suffix = 'key';
export const search_history_keyword_key = `${prefix}-history-keyword-${suffix}`;
历史搜索组件
src/pages/search/history.vue
<template>
<div class="history" v-if="historys.length">
<h4 class="history-title">历史搜索</h4>
<transition-group class="g-list" tag="ul" name="list">
<li class="g-list-item" v-for="item in historys" :key="item" @click="$_selectitem(item)">
<span class="g-list-text">{{item}}</span>
<!-- .stop 禁止事件冒泡 -->
<i class="iconfont icon-delete" @click.stop="removeitem(item)"></i>
</li>
</transition-group>
<a href="javascript:;" class="history-btn" @click="showconfirm">
<i class="iconfont icon-clear" ></i>
清空历史搜索
</a>
</div>
</template>
<script>
import storage from 'assets/js/storage';
import {search_history_keyword_key} from 'pages/search/config';
import {searchmixin} from 'api/mixins';
export default {
name:'searchhistory',
data(){
return{
historys:[]
}
},
mixins:[searchmixin],
created(){
this.getkeyword();
},
methods:{
update(){
this.getkeyword();
},
getkeyword(){
this.historys=storage.get(search_history_keyword_key,[]);
this.$emit('loaded');
},
removeitem(item){
this.historys=this.historys.filter(val=>val!==item);//点击后删除该项
storage.set(search_history_keyword_key,this.historys);//更新缓存
this.$emit('remove-item');
},
showconfirm(){
this.$emit('show-confirm');
},
clear(){
storage.remove(search_history_keyword_key);
}
}
}
</script>

border-bottom: 1px solid $border-color;
color: #686868;
&:last-child {
border-bottom: none;
}
}
.g-list-text {
flex: 1;
line-height: 1.5;
@include ellipsis();
}
src/assets/scss/index.scss
@import 'icons';
@import 'list';
*{

搜索结果页
src/pages/search/result.vue
<template>
<div class="result">
<div class="loading-container" v-show="loading">
<me-loading/>
</div>
<ul class="g-list" v-show="!loading && results.length">
<li
class="g-list-item"
v-for="(item, index) in results"
:key="index"
@click="$_selectitem(item[0])"
>
<span class="g-list-text">{{item[0]}}</span>
</li>
</ul>
<div class="no-result" v-show="!loading && !results.length">没有结果</div>
</div>
</template>
<script>
import meloading from 'components/loading';
import {getsearchresult} from 'api/search';
import {searchmixin} from 'api/mixins';
export default {
name:'searchresult',
components:{
meloading
},
data(){
return{
results:[],
loading:false
}
},
props:{
query:{
type:string,
default:''
}
},
mixins:[searchmixin],
watch:{
query(query){
this.getresults(query);
}
},
methods:{
getresults(keyword){
if(!keyword){
return;
}
this.loading=true;
getsearchresult(keyword).then(data=>{
console.log(data);
if(data){
this.results=data;
this.loading=false;
}
})
}
}
}
</script>
修改src/api/search.js
import axios from 'axios';
import jsonp from 'assets/js/jsonp';
//获取热门搜索数据 ajax
export const gethot=()=>{
return axios.get('http://www.imooc.com/api/search/hot').then(res=>{
res=res.data.hotkeyword;
if(res && res.owner){
return res.owner;
}
throw new error('没有成功获取到数据');
}).catch(err=>{
console.log(err);
});
}
//获取搜索框的搜索结果
export const getsearchresult=keyword=>{
const url='https://suggest.taobao.com/sug';
const params={
q:keyword,
code:'utf-8',
area:'c2c',
nick:'',
sid:null
};
//https://suggest.taobao.com/sug?q=apple&code=utf-8&area=c2c&nick=&sid=null&callback=jsonp5
return jsonp(url, params, {
param: 'callback'
}).then(res => {
console.log(res);
if (res.result) {
// console.log(res);
return res.result;
}
throw new error('没有成功获取到数据！');
}).catch(err => {
if (err) {
console.log(err);
}
});
};
最后，当删除历史搜索之后，也需要更新滚动条
修改src/pages/search/index.vue
修改src/pages/search/history.vue
（因为页面加载时有100ms延迟的动画，因此这里更新滚动条也需要相同的延迟）
注意滚动条组件的更新操作，需要使用 $nexttick( ) 实现异步
