nodejs+vue+elementui学生竞赛管理系统65o97
您的问题似乎是在询问如何使用Node.js、Vue.js和Element UI来创建一个学生竞赛管理系统。这是一个较为复杂的项目,涉及后端和前端的开发。以下是一个简化的指南和代码示例:
后端(Node.js 和 Express):
安装所需依赖:
npm install express mongoose
创建一个简单的Express服务器并连接MongoDB:
const express = require('express');
const mongoose = require('mongoose');
const app = express();
const port = 3000;
mongoose.connect('mongodb://localhost:27017/student-contest-system', { useNewUrlParser: true });
app.listen(port, () => {
console.log(`Server running on port ${port}`);
});
定义学生竞赛信息的模型和路由:
const Contest = mongoose.model('Contest', new mongoose.Schema({
name: String,
date: Date,
location: String
}));
app.get('/contests', async (req, res) => {
try {
const contests = await Contest.find();
res.json(contests);
} catch (err) {
res.status(500).send('Error fetching contests.');
}
});
app.post('/contests', async (req, res) => {
const newContest = new Contest(req.body);
try {
const savedContest = await newContest.save();
res.status(201).send(savedContest);
} catch (err) {
res.status(500).send('Error saving contest.');
}
});
前端(Vue.js 和 Element UI):
安装Vue和Element UI依赖:
npm install vue vue-router element-ui
创建一个Vue项目并使用Element UI:
// main.js
import Vue from 'vue';
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import App from './App.vue';
Vue.use(ElementUI);
new Vue({
render: h => h(App),
}).$mount('#app');
列出竞赛信息和添加竞赛的组件:
<template>
<div>
<el-button type="primary" @click="handleAddContest">添加竞赛</el-button>
<el-table :data="contests" style="width: 100%">
<el-table-column prop="name" label="名称"></el-table-column>
<el-table-column prop="date" label="日期"></el-table-column>
<el-table-column prop="location" label="地点"></el-table-column>
</el-table>
<el-dialog :visible.sync="dialogVisible" title="添加竞赛">
<el-form :model="newContest">
<el-form-item label="名称">
<el-input v-model="newContest.name"></el-input>
</el-form-item>
<el-form-item label="日期">
<el-date-picker v-model="newContest.date" type="date" placeholder="选择日期"></el-date-picker>
</el-form-item>
<el-form-item label="地点">
<el-input v-model="newContest.location"></el-input>
</el-form-item>
