2018.12.21 vue总结

技术

一、vue2.9.6版本起步

  1. 先安装node环境

    Node下载

  2. 再安vue的装脚手架

    1
    npm install -g vue-cli

  3. 创建项目

1
vue init webpack my-project

二、vue3.0版本起步

关于旧版本

Vue CLI 的包名称由 vue-cli 改成了 @vue/cli。 如果你已经全局安装了旧版本的 vue-cli(1.x 或 2.x)，你需要先通过 npm uninstall vue-cli -g 或 yarn global remove vue-cli 卸载它。

1.安装脚手架

1
npm install -g @vue/cli

2.检查版本是否安装正确

1
vue --version

3.查看版本号

1
vue -V

4.创建项目

1
vue create weibo

5.定位到该文件夹

1
cd weibo

6.启动服务器

1
npm run serve

三、在vue2.9.6脚手架用vuxUI配置

wux官方文档

1.在项目里安装vux 

1
npm install vux --save-dev

2.安装vux-loader （这个vux文档中没有明文跟你说要安装的啦） 

1
npm install vux-loader --save-dev

3.安装less-loader

（这个是用以正确编译less源码，否则会出现 ‘ Cannot GET / ‘，自己看package.json，如果安装了，就不用装啦！）

1
npm install less less-loader --save-dev

4.在build文件夹下webpack.base.conf.js 文件进行配置

const vuxLoader = require('vux-loader') //【新加上去的】
const webpackConfig = originalConfig //【originalConfig就是原来的 


//module.exports出去的代码，把它整个赋值给变量 webpackConfig】
// 【在最后加多一句，这里就是引用插件vux啦！】
module.exports = vuxLoader.merge(webpackConfig, { plugins: ['vux-ui'] })

5.最后别忘了，在resolve: { extensions: [‘.js’, ‘.vue’, ‘.json’,’.less’]里加入.less。

1
resolve: { extensions: ['.js', '.vue', '.json','.less']

const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
const vuxLoader = require('vux-loader') 

function resolve (dir) {
  return path.join(__dirname, '..', dir)
}

const createLintingRule = () => ({
//test: /\.(js|vue)$/,
//loader: 'eslint-loader',

const webpackConfig = {
  context: path.resolve(__dirname, '../'),
  entry: {
    app: './src/main.js'
  },
  output: {
    path: config.build.assetsRoot,
    filename: '[name].js',
    publicPath: process.env.NODE_ENV === 'production'
      ? config.build.assetsPublicPath
      : config.dev.assetsPublicPath
  },
  resolve: {

    alias: {

  module: {
    rules: [

      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: vueLoaderConfig
      },
      {
        test: /\.js$/,

        }
      }
    ]
  },
  node: {
    // prevent webpack from injecting useless setImmediate polyfill because Vue
    // source contains it (although only uses it if it's native).
    setImmediate: false,
    // prevent webpack from injecting mocks to Node native modules
    // that does not make sense for the client
    dgram: 'empty',
    fs: 'empty',
    net: 'empty',
    tls: 'empty',
    child_process: 'empty'
  }
}
module.exports = vuxLoader.merge(webpackConfig, { plugins: ['vux-ui'] })

7.需要什么在main.js里面引入即可，例如

1

import { Tab, TabItem } from 'vux'

Vue.component('tab', Tab)
Vue.component('tab-item', TabItem)

四、底部导航制作步骤

思路：底部导航动态切换的是路由 ，然后当你点击前有个未选中时的颜色，点击后有个选中时的颜色，这时图片就要动态切换路径，文字就要动态设置颜色，我用的是组件复用的方式，当你点击时通知向vuex仓库传递索引，别的页面拿到索引，动态选中颜色

1.先下载vue-router

1
npm install vue-router --save-dev

2.在src里面新建router文件夹，在router里面新建index.js文件,搭建好路由

import Vue from 'vue'
import Router from '	'

Vue.use(Router)

export default new Router({
	routes: [{
		path: '/',
		name: 'home',
		redirect: '/home'
	},
	{
		path: '/home',
		name: 'home',
		component: resolve => require(['@/pages/Home.vue'], resolve),
	},
	{
		path: '/transaction',
		name: 'transaction',
		component: resolve => require(['@/pages/Transaction.vue'], resolve),
	},	{
		path: '/athletics',
		name: 'athletics',
		component: resolve => require(['@/pages/Athletics.vue'], resolve),
	},
	{
		path: '/information',
		name: 'information',
		component: resolve => require(['@/pages/Information.vue'], resolve),
	},
	{
		path: '/mine',
		name: 'mine',
		component: resolve => require(['@/pages/Mine.vue'], resolve),
	}
	]
})

3.新建footerBar搭建结构

                <li v-for="(f,index) in footerBar" :key="index" :class="{active:idx==index}" @click="toggle(index)">
                    <img :src='idx===index?f.selectSrc:f.src' alt="">
                    <span>{{f.title}}</span>
                    </li>
            </ul>
        </div>
    
</template>
