如何使用 Vue+html 突出顯示搜索查詢

Question

在這里我的搜索正在工作，但我是一個新手，不知道如何使用 npm ......我正在使用 HTML 和 VueJS 來實現這一點，並成功創建了搜索過濾器，但無法實現高亮過濾器..一些線索是使用的 markjs.io 和其他一些自定義 vuejs 過濾器，但無法實現它們。

class Post {
  constructor(title, link, author, img, course, coursel, cours, coursl, cour, courl, cou, coul, co, col) {
    this.title = title;
    this.link = link;
    this.author = author;
    this.img = img;
    this.course = course;
    this.coursel = coursel;
    this.cours = cours;
    this.coursl = coursl;
    this.cour = cour;
    this.courl = courl;
    this.cou = cou;
    this.coul = coul;
    this.co = co;
    this.col = col;
  }
}
const app = new Vue({
  el: "#app",
  data: {
    search: "",
    postList: [
      new Post("abc", null, "xyz", "wqw", "qwe", "", " ", null, " ", null, " ", null, " ", null, );
    ]
  },
  computed: {
    filteredList() {
      return this.postList.filter(post => {
        return post.title.toLowerCase().includes(this.search.toLowerCase()) ||
          post.author.toLowerCase().includes(this.search.toLowerCase()) || 
          post.course.toLowerCase().includes(this.search.toLowerCase()) || 
          post.cours.toLowerCase().includes(this.search.toLowerCase()) || 
          post.cour.toLowerCase().includes(this.search.toLowerCase()) || 
          post.cou.toLowerCase().includes(this.search.toLowerCase()) || 
          post.co.toLowerCase().includes(this.search.toLowerCase());
      });
    }
  }
});

這是我正在使用的 HTML 代碼

<div id="app">
  <div class="search-wrapper">
    <input type="text" v-model="search" placeholder="Search"
      onfocus="if(this.value==this.defaultValue)this.value=''"    
      onblur="if(this.value=='')this.value=this.defaultValue" />
  </div>
  <div class="wrapper">
    <div class="col-lg-12 col-md-4 card" v-for="post in filteredList">
      <a v-bind:href="post.link" target="_blank">
        <img v-bind:src="post.img"/> 
        <div style="line-height:20%;">
          <br>
        </div>
        <font size="2">{{ post.author }}</font>
        <div class="brmedium"></div>
        <font size="5"><b><i><em>{{ post.title }}</em></i></b></font>
      <a v-bind:href="post.coursel" title="View Credential" target="_blank"><font size="3">{{ post.course }}</font></a>
      <a v-bind:href="post.coursl" title="View Credential" target="_blank"><font size="3">{{ post.cours }}</font></a>
      <a v-bind:href="post.courl" title="View Credential" target="_blank"><font size="3">{{ post.cour }}</font></a>
      <a v-bind:href="post.coul" title="View Credential" target="_blank"><font size="3">{{ post.cou }}</font></a>
      <a v-bind:href="post.col" title="View Credential" target="_blank"><font size="3">{{ post.co }}</font></a>
      </a>
    </div>
  </div>
</div>

<template>
  <div>
    <input v-model="text" @input="input" />
    <p id="x">

<script>
/*eslint-disable */
export default {
  data() {
    return {
      t: String(""),
      text: String(""),
    };
  },
  mounted() {
    this.t = document.querySelector("#x").innerText;
  },
  methods: {
    input() {
      document.querySelector("#x").innerHTML = this.t.replaceAll(
        this.text,
        `<span class='h'>${this.text}</span>`
      );
    },
  },
};
</script>

<style>
.h {
  background: red;
}
</style>
