Vue 实现淘宝搜索功能

淘宝搜索功能涉及关键词输入、实时搜索建议、搜索结果展示等核心模块。以下是基于 Vue 的实现方案：

搜索框与关键词输入

使用 Vue 的 v-model 实现双向绑定，监听用户输入：

vue实现淘宝搜索

<template>
  <div class="search-container">
    <input 
      v-model="searchQuery" 
      @input="handleInput" 
      placeholder="搜索商品..."
    />
    <button @click="performSearch">搜索</button>
  </div>
</template>

export default {
  data() {
    return {
      searchQuery: '',
      suggestions: []
    }
  },
  methods: {
    handleInput() {
      if (this.searchQuery.trim()) {
        this.fetchSuggestions();
      }
    }
  }
}

实时搜索建议

通过防抖函数优化高频请求：

import { debounce } from 'lodash';

export default {
  created() {
    this.debouncedFetch = debounce(this.fetchSuggestions, 300);
  },
  methods: {
    handleInput() {
      this.debouncedFetch();
    },
    async fetchSuggestions() {
      try {
        const res = await axios.get('/api/suggestions', {
          params: { q: this.searchQuery }
        });
        this.suggestions = res.data;
      } catch (error) {
        console.error(error);
      }
    }
  }
}

搜索结果展示

使用条件渲染展示结果列表：

vue实现淘宝搜索

<ul v-if="suggestions.length" class="suggestion-list">
  <li 
    v-for="(item, index) in suggestions" 
    :key="index"
    @click="selectSuggestion(item)"
  >
    {{ item }}
  </li>
</ul>

完整搜索逻辑

整合搜索执行与结果分页：

export default {
  data() {
    return {
      searchResults: [],
      currentPage: 1,
      totalPages: 0
    }
  },
  methods: {
    async performSearch() {
      const params = {
        q: this.searchQuery,
        page: this.currentPage
      };

      const res = await axios.get('/api/search', { params });
      this.searchResults = res.data.items;
      this.totalPages = res.data.totalPages;
    },
    selectSuggestion(item) {
      this.searchQuery = item;
      this.performSearch();
    }
  }
}

样式优化

添加基础样式提升用户体验：

.search-container {
  position: relative;
  width: 500px;
  margin: 0 auto;
}

.suggestion-list {
  position: absolute;
  width: 100%;
  background: white;
  border: 1px solid #eee;
  max-height: 300px;
  overflow-y: auto;
}

.suggestion-list li {
  padding: 8px 12px;
  cursor: pointer;
}

.suggestion-list li:hover {
  background-color: #f5f5f5;
}
