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）

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）






  $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;
 }

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






  .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;
    }
  }

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






$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;
 }

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







  $border-color: #e5e5e5;
  $font-size-base: 12px;
  $font-size-l: $font-size-base + 2;
  $border-color: #e5e5e5;

  @mixin flex-center($direction: row) {
    display: flex;
    justify-content: center;
    align-items: center;
    flex-direction: $direction;
  }

 .history {
  padding-bottom: 30px;
  background-color: #fff;

  &-title {
   height: 34px;
   line-height: 34px;
   padding: 0 10px;
   font-size: $font-size-l;
   font-weight: bold;
  }

  &-btn {
   @include flex-center();
   width: 80%;
   height: 40px;
   background: none;
   border: 1px solid #ccc;
   border-radius: 4px;
   margin: 0 auto;
   color: #686868;

   .iconfont {
    margin-right: 5px;
   }
  }
 }

 .g-list {
  border-top: 1px solid $border-color;
  border-bottom: 1px solid $border-color;
  margin-bottom: 20px;
 }

 .list {
  &-enter-active,
  &-leave-active {
   transition: height 0.1s;
  }

  &-enter,
  &-leave-to {
   height: 0;
  }
 }

列表样式统一抽离出去

src/assets/scss/_list.scss

// list
@mixin flex-between() {
  display: flex;
  justify-content: space-between;
  align-items: center;
 }

//ellipsis
@mixin ellipsis() {
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: nowrap;
 }

 $border-color: #e5e5e5;
 
.g-list {
 padding-left: 10px;
}
.g-list-item {
 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
  width:100%;
  height:100%;
}
ul,li{
  list-style:none;
}
a{
  text-decoration: none;
  color:#333;
}

确认框组件

src/components/comfirm/index.vue







$search-z-index: 1200;
$search-popup-z-index: $search-z-index + 10;
$modal-bgc: rgba(0, 0, 0, 0.4);

@mixin flex-center($direction: row) {
 display: flex;
 justify-content: center;
 align-items: center;
 flex-direction: $direction;
}
@mixin ellipsis() {
 overflow: hidden;
 text-overflow: ellipsis;
 white-space: nowrap;
}

 .mine-/confirm/i-wrapper {
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: $search-popup-z-index;
  @include flex-center();
  background-color: $modal-bgc;
 }

 .mine-confirm {
  overflow: hidden;
  width: 88%;
  background-color: #fff;
  border-radius: 10px;
  font-size: 16px;

  &-title {
   padding: 20px 15px 0;
   font-size: 18px;
   text-align: center;
   @include ellipsis();

   & + .mine-/confirm/i-msg {
    padding-top: 20px;
    padding-bottom: 20px;
   }
  }

  &-msg {
   padding: 40px 15px;
   text-align: center;
   line-height: 1.5;
  }

  &-btns {
   display: flex;
  }

  &-btn {
   flex: 1;
   height: 44px;
   line-height: 44px;
   background: none;
   border: none;
  }

  &-cancel {
   border-top: 1px solid #e3e5e9;
  }

  &-ok {
   background-color: #f23030;
   color: #fff;
  }
 }

 .mine-confirm {
  &-enter-active,
  &-leave-active {
   transition: opacity 0.3s;
  }

  &-enter,
  &-leave-to {
   opacity: 0;
  }

  &-enter-active {
   .mine-confirm {
    animation: bounce-in 0.3s;
   }
  }
 }

 // https://cn.vuejs.org/v2/guide/transitions.html#CSS-动画
 @keyframes bounce-in {
  0% {
   transform: scale(0);
  }
  50% {
   transform: scale(1.1);
  }
  100% {
   transform: scale(1);
  }
 }

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=>{
    
    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
