vue搜索页开发实例代码详解（热门搜索，历史搜索，淘宝接口演示）

首先完成这个伪搜索框

vue搜索页开发实例代码详解（热门搜索，历史搜索，淘宝接口演示）

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

vue搜索页开发实例代码详解（热门搜索，历史搜索，淘宝接口演示）

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"htmlcode">



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 "htmlcode">



const prefix = 'mall-search';
const suffix = 'key';
export const SEARCH_HISTORY_KEYWORD_KEY = `${prefix}-history-keyword-${suffix}`;





历史搜索组件

     <!-- .stop 禁止事件冒泡 -->
     <i class="iconfont icon-delete" @click.stop="removeItem(item)"></i>
   </li>
  </transition-group>
  <a href="javascript:;" rel="external nofollow" class="history-btn" @click="showConfirm">
    <i class="iconfont icon-clear" ></i>
    清空历史搜索
  </a>
 </div>
</template>

<script>

  },
  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);
    }
  }
}

列表样式统一抽离出去

 overflow: hidden;
 @include flex-between();
 height: 44px;
 padding-right: 10px;
 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';

*{
  margin:0;
  padding:0;
}
html,body{
  // 必须设置，否则内容滚动效果无法实现

 搜索结果页

src/pages/search/result.vue

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=>{

    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"text-align: center">vue搜索页开发实例代码详解（热门搜索，历史搜索，淘宝接口演示）


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
