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

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>
