发现宝藏
前些天发现了一个巨牛的人工智能学习网站,通俗易懂,风趣幽默,忍不住分享一下给大家。【宝藏入口】。
前言
为了巩固所学的知识,作者尝试着开始发布一些学习笔记类的博客,方便日后回顾。当然,如果能帮到一些萌新进行新技术的学习那也是极好的。作者菜菜一枚,文章中如果有记录错误,欢迎读者朋友们批评指正。
一、生命周期
1.生命周期 & 生命周期四个阶段

三、工程化开发入门
1. 工程化开发和脚手架
2. 脚手架目录&项目运行流程
3. 组件化
- main.js
// 文件核心作用:导入App.vue,基于App.vue创建结构渲染index.html
// 1. 导入 Vue 核心包
import Vue from 'vue'
// 2. 导入 App.vue 根组件
import App from './App.vue'
// 提示:当前处于什么环境 (生产环境 / 开发环境)
Vue.config.productionTip = false
// 3. Vue实例化,提供render方法 → 基于App.vue创建结构渲染index.html
new Vue({
// el: '#app', 作用:和$mount('选择器')作用一致,用于指定Vue所管理容器
// render: h => h(App),
render: (createElement) => {
// 基于App创建元素结构
return createElement(App)
}
}).$mount('#app')
- App.vue
<template>
// vue2只允许有一个根元素
<div class="App">
<div class="box" @click="fn"></div>
</div>
</template>
<script>
// 导出的是当前组件的配置项
// 里面可以提供 data(特殊) methods computed watch 生命周期八大钩子
export default {
created () {
console.log('我是created')
},
methods: {
fn () {
alert('你好')
}
}
}
</script>
<style lang="less">
/* 让style支持less
1. 给style加上 lang="less"
2. 安装依赖包 less less-loader
yarn add less less-loader -D (开发依赖)
*/
.App {
width: 400px;

4. 组件注册
1. 普通组件的注册
- HmFooter.vue
<template>
<div class="hm-footer">
我是hm-footer
</div>
</template>
<script>
export default {
}
</script>
<style>
.hm-footer {
height: 100px;
line-height: 100px;
text-align: center;
font-size: 30px;
background-color: #4f81bd;
color: white;
}
</style>
- HmHeader.vue
<template>
<div class="hm-header">
我是hm-header
</div>
</template>
<script>
export default {
}
</script>
<style>
.hm-header {
height: 100px;
line-height: 100px;
text-align: center;
font-size: 30px;
background-color: #8064a2;
color: white;
}
</style>
- HmMain.vue
<template>
<div class="hm-main">
我是hm-main
</div>
</template>
<script>
export default {
}
</script>
<style>
.hm-main {
height: 400px;
line-height: 400px;
text-align: center;
font-size: 30px;
background-color: #f79646;
color: white;
margin: 20px 0;
}
</style>
- App.vue
<template>
<div class="App">
<!-- 头部组件 -->
<HmHeader></HmHeader>
<!-- 主体组件 -->
<HmMain></HmMain>
<!-- 底部组件 -->
<HmFooter></HmFooter>
<!-- 如果 HmFooter + tab 出不来 → 需要配置 vscode
设置中搜索 trigger on tab → 勾上
-->
</div>
</template>
<script>
import HmHeader from './components/HmHeader.vue'
import HmMain from './components/HmMain.vue'
import HmFooter from './components/HmFooter.vue'
export default {
components: {
// '组件名': 组件对象,同名可以简写
HmHeader: HmHeader,
HmMain,
HmFooter
}
}
</script>
<style>
.App {
width: 600px;
height: 700px;
background-color: #87ceeb;
margin: 0 auto;
padding: 20px;
}
</style>
2. 普通组件的全局注册
四、综合案例:小兔鲜首页
1. 拆分模块-局部注册
- App.vue
<template>
<div class="App">
<!-- 快捷链接 -->
<XtxShortCut></XtxShortCut>
<!-- 顶部导航 -->
<XtxHeaderNav></XtxHeaderNav>
<!-- 轮播区域 -->
<XtxBanner></XtxBanner>
<!-- 新鲜好物 -->
<XtxNewGoods></XtxNewGoods>
<!-- 热门品牌 -->
<XtxHotBrand></XtxHotBrand>
<!-- 最新专题 -->
<XtxTopic></XtxTopic>
<!-- 版权底部 -->
<XtxFooter></XtxFooter>
</div>
</template>
<script>
import XtxShortCut from './components/XtxShortCut.vue'
import XtxHeaderNav from './components/XtxHeaderNav.vue'
import XtxBanner from './components/XtxBanner.vue'
import XtxNewGoods from './components/XtxNewGoods.vue'
import XtxHotBrand from './components/XtxHotBrand.vue'
import XtxTopic from './components/XtxTopic.vue'
import XtxFooter from './components/XtxFooter.vue'
export default {
data () {
return {
count: 0
}
},
components: {
XtxShortCut,
XtxHeaderNav,
XtxBanner,
XtxNewGoods,
XtxHotBrand,
XtxTopic,
XtxFooter,
}
}
</script>
<style>
</style>
2. 拆分组件-全局注册
- main.js
import Vue from 'vue'
import App from './App.vue'
import './styles/base.css' // css 样式重置
import './styles/common.css' // 公共全局样式
import './assets/iconfont/iconfont.css' // 字体图标的样式
import BaseGoodsItem from './components/BaseGoodsItem'
import BaseBrandItem from './components/BaseBrandItem'
Vue.component('BaseGoodsItem', BaseGoodsItem)
Vue.component('BaseBrandItem', BaseBrandItem)
Vue.config.productionTip = false
new Vue({
render: h => h(App),
}).$mount('#app')
