How to implement a Youdao dictionary-like page design in Vue?

Vue is a very popular JavaScript framework for building modern, high-performance web applications. In Vue, using component-based development to build pages makes it very convenient to implement various complex UI designs. This article will introduce how to use Vue to implement a page design similar to Youdao Dictionary.

1. Page design

Before starting the implementation of Vue, let’s take a look at the page design of imitating Youdao Dictionary. The design is divided into three main parts: the top navigation bar, the search box, and the search results list.

Top navigation bar: It consists of a logo and two navigation links. The logo can be clicked to return to the homepage. Navigation links generally include "Home" and "Translation".

Search box: includes an input box and a search button. Users can enter the word or phrase they want to query in the input box and click the search button to query.

Search result list: Query results are presented in list form, and each query result includes the definition and example sentences of the word or phrase.

2. Division of components

According to the page design, the entire page can be divided into three components: navigation bar component, search box component and search result component.

Navigation bar component: Mainly responsible for the style and logic of the top navigation bar.

Search box component: Mainly responsible for the style and logic of the search box.

Search result component: Mainly responsible for displaying the style and logic of query results.

3. Component implementation

1. Navigation bar component

First, you need to introduce the navigation bar component into Vue's App.vue.

<template>
  <div id="app">
    <nav-bar></nav-bar>
    <router-view></router-view>
  </div>
</template>

<script>
import NavBar from './components/NavBar.vue'

export default {
  name: 'App',
  components: {
    NavBar
  }
}
</script>

<style>
/* 全局样式 */
</style>

Next, create the NavBar.vue component and define the style and logic of the navigation bar.

<template>
  <div id="nav-bar">
    <div class="nav-left">
      <img src="./assets/logo.png" alt="logo" @click="backToHome">
      <div class="nav-link" @click="$router.push('/')">首页</div>
      <div class="nav-link" @click="$router.push('/translate')">翻译</div>
    </div>
    <div class="nav-right">
      <!-- 登录按钮等右侧组件 -->
    </div>
  </div>
</template>

<script>
export default {
  name: 'NavBar',
  methods: {
    backToHome() {
      this.$router.push('/')
    }
  }
}
</script>

<style>
/* 导航栏样式 */
</style>

2. Search box component

The search box component contains an input box and a search button. The user enters the word or phrase to be queried in the input box and clicks the search button. Make an inquiry. Similar to the navigation bar component, first introduce the search box component in App.vue.

<template>
  <div id="app">
    <nav-bar></nav-bar>
    <search-box></search-box>
    <router-view></router-view>
  </div>
</template>

<script>
import NavBar from './components/NavBar.vue'
import SearchBox from './components/SearchBox.vue'

export default {
  name: 'App',
  components: {
    NavBar,
    SearchBox
  }
}
</script>

<style>
/* 全局样式 */
</style>

Next, create the SearchBox.vue component and define the style and logic of the search box.

<template>
  <div id="search-box">
    <input type="text" class="search-input" v-model="searchWord">
    <button class="search-btn" @click="search">搜索</button>
  </div>
</template>

<script>
export default {
  name: 'SearchBox',
  data() {
    return {
      searchWord: ''
    }
  },
  methods: {
    search() {
      // 跳转到搜索结果页面，将searchWord作为查询参数
      this.$router.push({path: '/search', query: {word: this.searchWord}})
    }
  }
}
</script>

<style>
/* 搜索框样式 */
</style>

3. Search result component

The search result component is mainly responsible for displaying the style and logic of query results. First introduce the search result component in App.vue.

<template>
  <div id="app">
    <nav-bar></nav-bar>
    <search-box></search-box>
    <search-result v-if="$route.path === '/search'"></search-result>
    <router-view></router-view>
  </div>
</template>

<script>
import NavBar from './components/NavBar.vue'
import SearchBox from './components/SearchBox.vue'
import SearchResult from './components/SearchResult.vue'

export default {
  name: 'App',
  components: {
    NavBar,
    SearchBox,
    SearchResult
  }
}
</script>

<style>
/* 全局样式 */
</style>

Next, create the SearchResult.vue component and define the style and logic of the search results. Get the query parameter word in the created cycle hook, and get the query results by calling the external API.

<template>
  <div id="search-result">
    <div v-if="resultLoading" class="result-loading">正在查询...</div>
    <ul v-else class="result-list">
      <li v-for="(item, index) in resultList" :key="index">
        <h3 class="result-word">{{item.word}}</h3>
        <p class="result-translation">{{item.translation}}</p>
        <p class="result-example">{{item.example}}</p>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  name: 'SearchResult',
  data() {
    return {
      resultLoading: true,
      resultList: []
    }
  },
  created() {
    const query = this.$route.query
    if (query.word) {
      // 调用API查询结果
      this.resultLoading = false
      this.resultList = [...]
    }
  }
}
</script>

<style>
/* 搜索结果样式 */
</style>

Here we only briefly introduce the implementation method of the component. In actual development, it needs to be adjusted and improved according to specific needs.

4. Summary

Vue’s component-based development method is very flexible and can easily implement various complex UI designs.
