小編給大家分享一下Vue如何實現搜索結果高亮顯示關鍵字,希望大家閱讀完這篇文章之后都有所收獲,下面讓我們一起去探討吧!
Vue是一套用于構建用戶界面的漸進式JavaScript框架,Vue與其它大型框架的區別是,使用Vue可以自底向上逐層應用,其核心庫只關注視圖層,方便與第三方庫和項目整合,且使用Vue可以采用單文件組件和Vue生態系統支持的庫開發復雜的單頁應用。
Vue實現搜索結果高亮顯示關鍵字的具體代碼如下
1. 需要解決的問題
父組件將搜索的字段傳到子組件
子組件接受數據,正則匹配,并替換字段
2. 具體代碼
父組件代碼
<template> <div> <div v-if="showMe"> <div class="re_search"> <svg @click="$router.go(-1)"> <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#arrow-left.6f6409e" rel="external nofollow" ></use> </svg> <input type="search" v-model="search_text" class="v-md" placeholder="請輸入商品名稱" @keydown.enter="search_method"> </div> <OneBusiness v-for="(item, n) in search_res" :key="n" :item="item" :search_text="search_text"></OneBusiness> </div> <!--<!– 撐開Fixednav擋住的位置 –>--> <div class="space"></div> <!-- 固定導航欄 --> </div> </template> <script> import { mapGetters } from 'vuex'; import OneBusiness from './small_components/One_business'; import {getSearchData} from 'src/service/getData' export default { name: 'search', data () { return { showMe: false, search_text: '', // 搜索框內容 search_res: [] // 搜索結果 }; }, mounted () { this.$store.dispatch('setLoading', true); // 模擬加載 var time = Math.floor(Math.random() * 2000); console.log('模擬加載用時' + time); setTimeout(() => { this.$store.dispatch('setLoading', false); this.showMe = true; }, time); this.search_method(); }, computed: { ...mapGetters([ 'getFalseBussinessbrief' // 商家簡略信息 ]) }, methods: { async search_method () { var mainWord = this.$route.params.keyword; if (this.search_text !== '' && this.search_text !== this.$route.params.keyword) { mainWord = this.search_text; } this.search_text = mainWord; this.search_res = (await getSearchData(this.search_text)).obj.results; console.log(this.search_res); } }, components: { OneBusiness } }; </script> <style lang="less" scoped> .re_search{ background:#0096ff; line-height:0; padding: .2rem; svg{ width:.6rem; height:.6rem; } input[type="search"]{ display:inline-block; height:.9rem; width:8rem; outline: none; border: none; border-radius:.45rem; background:#f2f2f2; box-sizing: border-box; padding: 0 .5rem; font-size:.4rem; } } </style>
