nodejs：vue 3 + vite 作为前端，将 html 填入＜iframe＞，在线查询英汉词典

向 doubao.com/chat/ 提问：
node.js + js-mdict 作为后端，vue 3 + vite 作为前端，编写在线查询英汉词典

后端部分（express + `js-mdict` ）

详见上一篇：nodejs：express + js-mdict 作为后端，vue 3 + vite 作为前端，在线查询英汉词典

前端部分（Vue 3 + Vite）

1. 创建前端项目

node -v
v18.20.6
npm -v
10.8.2

cd \js
cnpm create vite@latest mydict-web --template vue
选 Vue 3
选 Javascript

项目结构‌：Vite 会自动创建一个基本的项目结构，包括 src目录下的组件、路由和状态管理等文件。主要文件和目录如下：

App.vue：根组件
main.js：应用程序入口
router：Vue Router配置
store：状态管理

在 public 中添加一些英汉字典的样式：oalecd8e.css , oalecd8e.js , uk_pron.png, us_pron.png,
copy jquery-3.2.1.min.js pulibc\jquery.js

修改 index.html 中的标题如下

<!DOCTYPE html>
<html lang="en"><head><meta charset="UTF-8" /><link rel="icon" type="image/svg+xml" href="/vite.svg" /><meta name="viewport" content="width=device-width, initial-scale=1.0" /><title>Vite 在线英汉词典查询</title></head><body><div id="app"></div><script type="module" src="/src/main.js"></script></body>
</html>

修改 src/main.js 如下

import { createApp } from 'vue'
import App from './App.vue'
import axios from 'axios'createApp(App).mount('#app')

vite 代理服务器（Proxy）的配置通常用于开发环境，以解决跨域请求等问题。
修改 vite.config.js 如下

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'// https://vite.dev/config/
export default defineConfig({plugins: [vue()],server: {proxy: {'/api': {target: 'http://localhost:8006', // 后端服务地址changeOrigin: true, // 是否改变源地址rewrite: (path) => path.replace(/^\/api/, '')}}}    
})

2. 安装依赖

cd mydict-web
cnpm install axios

cnpm install vue-router -S

package.json 如下

{"name": "mydict-web","private": true,"version": "0.1.0","type": "module","scripts": {"dev": "vite","build": "vite build","preview": "vite preview"},"dependencies": {"axios": "^1.7.9","vue": "^3.5.13","vue-router": "^4.5.0"},"devDependencies": {"@vitejs/plugin-vue": "^5.2.1","vite": "^6.1.0"}
}

3. 编写前端代码

修改 src/App.vue 文件：

<template><div id="app"><input v-model="sWord" placeholder="请输入英文单词" @keyup.enter="search" target="iframe">&nbsp; <button @click="search">查询</button>&nbsp; <button @click="prefix">前缀查询</button>&nbsp; <button @click="fuzzy">模糊查询</button><h3>查询结果</h3><div style="float:left; width:100%;"><div id="result" style="float:left; width:75%; height:500; border:2px;"><iframe ref="iframe" name="iframe" width="100%" height="500"> </iframe></div><div v-if="alist"><div v-html="alist" style="float:right; width:25%; height:500; border:2px;"></div></div></div><div v-if="error">{{ error }}</div></div>
</template><script setup>
import { ref } from 'vue';
import axios from 'axios';const sWord = ref('');
const result = ref('');
const error = ref('');
const iframe = ref(null);
const alist = ref(null);// 查询
const search = async () => {try {const response = await axios.get('/api/search', {params: {word: sWord.value}});let htm1 = response.data.result;const frame1 = iframe.value;if (frame1 && htm1) {let doc1 = frame1.contentWindow.document;doc1.open();doc1.write(htm1);doc1.close();}error.value = '';} catch (err) {result.value = '';error.value = err.response?.data?.error || '请求出错，请稍后重试';}
};// 前缀查询
const prefix = async () => {try {const response = await axios.get('/api/prefix', {params: {word: sWord.value}});let items = [];let wordls = response.data.wordls;wordls.forEach((item, i) => {if (i<=20){items[i] = `<a href="/api/query?word=${item}" target="iframe">${item}</a>`;}});if (items.length >0){ alist.value = items.join('<br>\n');}else { alist.value = '';}error.value = '';} catch (err) {alist.value = '';error.value = err.response?.data?.error || '请求出错，请稍后重试';}
};// 模糊查询
const fuzzy = async () => {try {const response = await axios.get('/api/fuzzy', {params: {word: sWord.value}});let items = [];let wordls = response.data.wordls;wordls.forEach((item, i) => {if (i<=20){items[i] = `<a href="/api/query?word=${item}" target="iframe">${item}</a>`;}});if (items.length >0){ alist.value = items.join('<br>\n');}else {alist.value = '';}error.value = '';} catch (err) {alist.value = '';error.value = err.response?.data?.error || '请求出错，请稍后重试';}
};</script><style scoped>
