UniApp Configuration and Implementation Techniques for Implementing Search Function

With the rapid development of the mobile Internet, the search function has become one of the necessary functions for almost every application. For UniApp, a multi-platform application development framework based on Vue.js, implementing search functions has become simpler and more efficient. This article will introduce the configuration and implementation techniques of the search function in UniApp, and come with code examples to help readers get started quickly.

1. Configure the search function

1. Create a search page in the page folder of the uni-app project and name it search.vue.

Code example:

<template>
  <view>
    <!-- 搜索框 -->
    <input class="search-input" type="text" v-model="keyword" placeholder="请输入搜索关键词" @input="onInput" />

    <!-- 搜索结果列表 -->
    <ul class="search-list">
      <li v-for="(item, index) in searchResults" :key="index">
        {{ item.title }}
      </li>
    </ul>
  </view>
</template>

<script>
export default {
  data() {
    return {
      keyword: '',         // 搜索关键词
      searchResults: []    // 搜索结果列表
    }
  },
  methods: {
    onInput() {
      // 在这里编写搜索功能的实现代码
    }
  }
}
</script>

<style>
.search-input {
  width: 100%;
  height: 40px;
  padding: 0 10px;
}

.search-list {
  margin-top: 10px;
}

.search-list li {
  line-height: 30px;
}
</style>

2. Introduce the search page into the entry page or the page that needs to use the search function.

Code example:

<template>
  <view>
    <!-- 其他页面内容 -->

    <!-- 引入搜索页面 -->
    <search></search>
  </view>
</template>

<script>
import search from '@/pages/search.vue'

export default {
  components: {
    search
  }
}
</script>

2. Implement the search function

1. Write the implementation code of the search function in the onInput method.

Code example:

onInput() {
  // 发送搜索请求
  uni.request({
    url: 'https://api.example.com/search',      // 接口地址
    method: 'GET',                              // 请求方式
    data: {
      keyword: this.keyword                      // 搜索关键词
    },
    success: (res) => {
      // 请求成功，处理搜索结果
      this.searchResults = res.data.results;
    },
    fail: (err) => {
      // 请求失败，处理错误信息
      console.log('搜索请求失败', err);
    }
  });
}

2. Fill in the real search interface address in the interface address url, and set the appropriate request method (GET or POST).
3. In the success callback function, process the successfully returned search results and assign the results to searchResults, and the search results list on the page will be automatically updated.

In this way, we have completed the configuration and implementation of the search function in UniApp. Readers can expand and optimize the search function according to their own needs.

Summary

This article introduces the techniques for configuring and implementing search functions in UniApp, and provides corresponding code examples. Through the above steps, we can easily add search functions to UniApp applications and improve user experience. I hope this article will be helpful to UniApp developers and beginners.
