脚本之家收集整理的这篇文章主要介绍了关于vue的常识问题及解决方法脚本之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随脚本之家小编过来看看吧!

一.VSCode开发必备插件

1.Beautify:语法高亮;

2.Bracket Pair Colorizer :对括号对进行着色;

3.ESLint:ESLint插件,高亮提示;

4.HTML CSS Support:css提示(支持vue);

5.HTML Snippets:自动帮你输入HTML标签;

6.veter:目前比较好的Vue语法高亮;

7.vscode-icons:文件图标,方便定位文件;

8.Vue 2 Snippets:API添加了代码片段;

二.页面文件路由跳转文件配置

文件在router文件夹下的index.js下

//首页
import index from '@/components/pages/My/index'
......
routes: [
{
path:'/index',
name:'index',
component:index
}
]

 

三.跨域解决方法

文件在config文件夹下的index.js下

module.exports = {
dev: {
// Paths
assetsSubDirectory: 'static',
assetsPublicPath: '/',
proxyTable: {
'/api': {
target:'http://192.168.1.240:18080',
changeOrigin: true,
     }
}
},
......
 
 
四.接口API
 
#由于接口文件端口可能会进行更改,使用在全局里面设置端口,在分页面进行引用;
 
在全局main.js里面创建并引用全局端口替代文件
//main.js
import global from './components/global/global';
Vue.prototype.GLOBAL = global;
 
//global.vue
<script>
// const proxy = 'http://47.92.104.142:8090';
const proxy = '/api';
const userId =12;
const userid =11;
export default
{
proxy,
userId,
userid,
}
</script>
 
//页面引用接口写法
method:'post',
url:this.GLOBAL.proxy+'/app/course/study.do?courseId='+this.courseId+'&userId='+this.GLOBAL.userId,
 
 
五.axios
 

axios简介:基于 Promise,用于浏览器和 nodejs 的与服务器端通信库。

axios安装:npm install axios --save;

axios引用import axios from 'axios';

六.vuex的安装使用

1.在项目里安装vux

npm install vux --save;

2.安装vux-loader (这个vux文档似乎没介绍,当初没安装结果报了一堆错误)

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 / ')

npm install less less-loader --save-dev

4.安装yaml-loader  (以正确进行语言文件读取,我没安装似乎也没报错)

npm install yaml-loader --save-dev

5.在build/webpack.base.conf.js 文件进行配置、

'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
function resolve (dir) {
return path.join(__dirname,'..',dir)
}
//vux的相关配置
const vuxLoader = require('vux-loader')
 
let webpackConfig = {
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: {
extensions: ['.js','.vue','.json'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'),
}
},
module: {
rules: [
{
test: /\.vue$/,
loader: 'vue-loader',
options: vueLoaderConfig
},
{
test: /\.js$/,
loader: 'babel-loader',
include: [resolve('src'),resolve('test'),resolve('node_modules/webpack-dev-server/client')]
},
{
test: /\.(PNG|jpe?g|gif|svg)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('img/[name].[hash:7].[ext]')
}
},
{
test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
name: utils.assetsPath('media/[name].[hash:7].[ext]')
}
},
{
test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
}
}
]
},
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'
}
}
//这个必须放在下面
module.exports = vuxLoader.merge(webpackConfig,{
plugins: ['vux-ui','progress-bar','duplicate-style']
})
 
6.vux组件库css的设置
在全局组件index.html里面设置全局css替换掉组件自带的样式,记得添加!important
 
<link href="static/less/less.css" rel="stylesheet"/>
 
 
七.公用顶部导航栏组件
 
 
<div class="notification-top">
<div class="notification">
<div>
<slot name="left"></slot>
</div>
<div><slot name="center"></slot></div>
<div>
<slot name="right"></slot>
</div>
</div>
</div>
<script>
</script>
<style>
width: 100%;
height: 45px;
line-height: 45px;
background-color: #3ba4f5;
}
width: 92%;
height: 45px;
margin: auto;
display: flex;
flex-direction: row;
align-items: center;
justify-content: space-between;
position: relative;
}
.notification div:nth-child(1){
width: 12px;
height: 20px;
display: flex;
justify-content: flex-start;
}
.notification div:nth-child(1) img{
width: 100%;
height: 100%;
}
.notification div:nth-child(2){
font-size: 16px;
height: 45px;
color: #fff;
position: absolute;
left: 50%;
transform: TranslateX(-50%);
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: 1;
overflow: hidden;
}
.notification div:nth-child(3){
font-size: 14px;
color: #fff;
display: flex;
justify-content: flex-end;
align-items: center;
}
</style>
 
//其他页面
 
<img @click="jumpBack" slot="left" class="backWhite" align="center" src="../../../../../static/imgs/Online_course/icon_arrow_left.PNG"/>
<span slot="center">{{chapterTitle||chapterstudy.chapterTitle}}</span>
<span slot="right" @click="section">章节</span>
 
//顶部标题栏
import notification from '@/components/pages/My/notification'
 
export default {
components: {
},
...
}
持续更新中...
