一、Ajax
1、简介
- 概念:异步的JavaScript和XML
- 作用:
- 数据交换:通过Ajax可以给服务器发送请求,并获取服务器响应数据
- 异步交互:可以在不重新加载整个页面情况下,与服务器交换数据并更新部分网页端技术,如:搜索框联想功能,校验用户名
2、Axios (没懂 暂留)
(1)请求方式别名
- axios.get(url[,config])
- axios.delete(url[,config])
- axios.post(url[,data,config])
- axios.put(url[,data,config])
(2)发送get请求
axios.get("http://yapi.smart-xwork.cn/mock/169327/emp/list").then(result=>{console.log(request.data); })
(3)发送post请求
axios.post("http://yapi.smart-xwork.cn/mock/169327/emp/list","id=1").then(result=>{console.log(request.data); })

<!DOCTYPE html> <html lang="en"> <head><meta charset="UTF-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>Ajax-Axios-案例</title><script src="js/axios-0.18.0.js"></script><script src="js/vue.js"></script></head> <body><div id="app"><table border="1" cellspacing="0" width="60%"><tr><th>编号</th><th>姓名</th><th>图像</th><th>性别</th><th>职位</th><th>入职日期</th><th>最后操作时间</th></tr><tr align="center" v-for="(emp,index) in emps"><td>{{index + 1}}</td><td>{{emp.name}}</td><td><img :src="emp.image" width="70px" height="50px"></td><td><span v-if="emp.gender == 1">男</span><span v-if="emp.gender == 2">女</span></td><td>{{emp.job}}</td><td>{{emp.entrydate}}</td><td>{{emp.updatetime}}</td></tr></table></div> </body> <script>new Vue({el: "#app",data: {emps:[]},mounted () {//发送异步请求,加载数据axios.get("http://yapi.smart-xwork.cn/mock/169327/emp/list").then(result => {this.emps = result.data.data;})}}); </script> </html>
二、前端工程化
1、Vue项目-目录结构
2、Vue项目-启动
(1)vscode页面启动
(2)cmd命令框启动
npm run serve
3、配置Vue端口号
4、Vue项目开发流程
Vue组件文件以.vue结尾,每个组件由三部分组成
- <template> 模板部分,生成HTML代码
- <script> 控制模板的数据来源和行为
- <style> css样式部分
<template><div id="app"><h1>{{message}}</h1></div>
</template><script>
export default{ //设置导出模块 可以在别处用import导入data(){return {message:"坚持不懈哇哇!"}},methods:{}
}
</script><style>#app{text-align: center;color: cadetblue;}
</style>
三、Vue组件库 - Element
Element 是优化版组件库(也就是炫彩ui组件皮肤)
1、快速入门
(1)在main.js引入ElementUI组件库
//引入Element ui组件
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';Vue.use(ElementUI);
(2)根据文档选择想要的皮肤 复制代码

};
</script><style>
</style>
四、Vue路由
1、概念
- <router-link to> 请求链接组件,浏览器会传递到该链接
- <router-view> 动态视图组件,渲染展示对应路由路径
2、案例
通过Vue路由完成左侧菜单栏点击切换效果
① 配置路由路径
import Vue from 'vue'
import VueRouter from 'vue-router'Vue.use(VueRouter)const routes = [{path: '/emp',name: 'emp',component: () => import('../views/item 2/EmpView.vue') },{path: '/dept',name: 'dept',component: () => import('../views/item 2/DeptView.vue')}
]const router = new VueRouter({routes
})export default router
② 给侧栏标签添加<router-link to>标签
<el-aside width="230px" style="border: 1px solid #eee"><el-menu :default-openeds="['1', '3']"><el-submenu index="1"><template slot="title"><i class="el-icon-message"></i>系统信息管理</template><el-menu-item index="1-1"><router-link to="/dept">部门管理</router-link></el-menu-item><el-menu-item index="1-2"><router-link to="/emp">员工管理</router-link></el-menu-item></el-submenu></el-menu>
</el-aside>
③ 在APP.vue添加 <router-view>
<template><div><router-view></router-view></div>
</template>
五、打包部署
Day03-16. 打包部署_哔哩哔哩_bilibili
step1:点击允许build,进行打包
step2:此时目录出现dist文件,右键
step3:将dist文件内容复制,粘贴到nginx安装目录下的html目录下
step4:双击nginx.exe即可,在页面输入localhost:80(端口号)回车即可
