vue使用vue-router步骤:
1.安装并创建实例。
npm install vue-router
2.新建router 文件夹和router.js,并进行配置router.js。
import App from '../App.vue';
import {
createRouter,
createWebHashHistory
} from 'vue-router'
const routes = [{
path: '/',
component: App, //顶层路由,对应index.html
children: [{
//地址为空时跳转home页面
path: '',
redired: '/home'
},
//首页城市列表页
{
path: '/home',
component: () => import('../page/home/home.vue')
}
]
}]
const router = createRouter({
history: createWebHashHistory('/'),
routes
})
export default router
3.main.js 中引入 router并使用。
文件夹目录如下:
package.json:
{
"name": "vue-elm",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"build": "cross-env NODE_ENV=production webpack --config webpack.config.js",
"dev": "cross-env NODE_ENV=production webpack-dev-server"
},
"author": "",
"license": "ISC",
"dependencies": {
"vue": "^3.2.4",
"vue-loader": "^17.0.1",
"vue-router": "^4.1.6",
"vue-template-compiler": "2.3.3",
"webpack-dev-server": "^4.11.1"
},
"devDependencies": {
"cross-env": "^7.0.3",
"html-webpack-plugin": "^5.5.0",
"webpack-cli": "^5.0.0"
}
}
webpack.config.js:
const path = require('path')
const { VueLoaderPlugin } = require('vue-loader')
const isDev = process.env.NODE_ENV=='development'
const HtmlWebpackPlugin = require('html-webpack-plugin')
module.exports = {
mode: 'development',
entry: path.resolve(__dirname, './src/main.js'),
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'bundle.js'
},
module: {
rules: [{
test: /\.vue$/,
loader: 'vue-loader'
}]
},
plugins: [
new VueLoaderPlugin(),
new HtmlWebpackPlugin({
template:'./src/index.html',
inject: 'body'
})
]
}
if(isDev){
config.devtool='cheap-module-eval-source-map'//生成map文件
config.devServer={
port:8081,
host:'0.0.0.0'//使用本机ip也可以访问
}
}
main.js:
import {createApp } from 'vue'
import router from './router/router'
import App from './App.vue'
const dom = document.createElement('div')
document.body.append(dom)
const app = createApp(App);
app.use(router)
app.mount('#app')
index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>app title</title>
</head>
<body>
<div id="app"></div>
</body>
</html>
App.vue:
<template>
<div>
<router-view/>
</div>
</template>
<script>
export default {
name:'App',
data(){
return {
txt:'这是App.vue'
}
}
}
</script>
router.js:
import App from '../App.vue';
import {
createRouter,
createWebHashHistory
} from 'vue-router'
const routes = [{
path: '/',
component: App, //顶层路由,对应index.html
children: [{
//地址为空时跳转home页面
path: '',
redired: '/home'
},
//首页城市列表页
{
path: '/home',
component: () => import('../page/home/home.vue')
}
]
}]
const router = createRouter({
history: createWebHashHistory('/'),
routes
})
export default router
home.vue:
<template>
<div>home</div>
</template>
<script>
export default {
}
</script>
