最近想着一步步搭建一个前后端项目,将每一步详细的做出来。(如果有不足或者建议,也希望大佬们指出哦)
前端初始化
1.根据vue脚手架创建vue项目
这里可以用很多方法创建vue项目,大家看着创建吧,只要能创建出来就可以了(用的vue3)
这里我加了router和vuex,emm,就不用ts了(感觉还是js用的更好一点)
OK,项目创建完毕,即可开始写前端代码了。
2.安装依赖:
1.挑一个自己喜欢的组件库引用一手,这里我选用arco design(也没必要只用Element-ui,可以试试其他的)
npm install --save-dev @arco-design/web-vue
OKOK,开始下载
安装好了之后,我们还要安装一些必要的依赖,比如axios,sass这些,emmmm,目前就安装这几个吧。
npm install axios
npm install sass -D
然后根据组件库官网的操作进行引入
import { createApp } from 'vue' import ArcoVue from '@arco-design/web-vue'; import App from './App.vue'; import '@arco-design/web-vue/dist/arco.css'; const app = createApp(App); app.use(ArcoVue); app.mount('#app');
改造一下main.js中的代码
import { createApp } from 'vue' import App from './App.vue' import router from './router' import store from './store' import ArcoVue from '@arco-design/web-vue'; import '@arco-design/web-vue/dist/arco.css'; createApp(App).use(store).use(ArcoVue).use(router).mount('#app')
注意注意:引入组件库之后,可以找个组件看看能不能使用该组件库,以防万一;
呐,这里我们就去官网看看
很好,就是你了,表单布局,我们点击其下方代码,将其放入App.vue试试能不能用
好嘞,随机找一串串代码放到App.vue中试试(不要试着从图片中照抄我的哈,自己去官网找一个试试Arco Design Vue)咱,主打一个快速。
嚯,出现了!那么组件库是能用哒!
好,第二步也就完成了。
这里我建议每做几步就开启调试一下。
3.调整目录,初始化项目:
1.清空components(把HelloWorld.vue删了)
2.新建目录api,utils,views
3.把App.vue中用不到的代码都给删了,留一个 <router-view />就好了,然后,把router的index.js的代码全给注释了(emmm,直接删了感觉太麻烦,注释了后面写起来好做参照)
目前的目录结构就是这样了;
(App.vue就变成这样啦)
4.定义请求工具:
大家不要一开始写前端就直奔优美的”可跳转“页面,这边先整体规定一个向后端发请求的工具request.js
在utils目录下创建request.js文件:
import axios from 'axios';//导入axios //定义前缀 const URL = 'http://localhost:8080'; const instance = axios.create({URL}) //来一个响应拦截器 instance.interceptors.response.use( result=>{ if(result.data.code == 0){ return result.data; } //如果不为0则表示失败 alert(result.data.message||'出现错误') return Promise.reject(err);//异步的状态转化成失败的状态 }, err=>{ alert('服务异常'); return Promise.reject(err);//异步的状态转化成失败的状态 } ) export default instance;
解释一下这段代码:引入发请求的axios,然后定义一个开发时期的请求必有前缀(这里直接写http://localhost:8080其实是有问题的,对于后面出现的跨域问题....emmmm,其实前端后端都有方式解决,看情况吧,后面再讲),做一个相应拦截器,对结果进行判断,然后导出
(这里需要提示一下统一相应有哪些(不然可能会不太好理解))
后端那一块统一相应数据:code:0表示成功,1表示失败;msg: 提示信息;data:数据
前端代码编写开始!!
OK啊各位,初始化完成我们便要开始编写代码了。
首先,我们先明确一波步骤:
确定布局 --> 填充各部分代码 --> 后端插入
(如果涉及与后端的交互,遵循以下步骤
1.搭建页面(html,css)-> 2.绑定数据与事件 -> 3.调用后端接口)
好嘞,熟悉了吗各位,不熟练也没事,我们先找一个练练手。
先从组件库这里找到布局:
这布局,看似普通,实则帅的雅痞,就它了。引入代码
回到目录component下,创建一个新的文件GlobalPage.vue
(众所周知的小技巧:<vue>可快速构建vue文件)
<template> <a-layout style="height: 400px;"> <a-layout-header>Header</a-layout-header> <a-layout> <a-layout-sider theme="dark">Sider</a-layout-sider> <a-layout-content>Content</a-layout-content> </a-layout> <a-layout-footer>Footer</a-layout-footer> </a-layout> </template> <script> export default { } </script> <style scoped> .layout-demo :deep(.arco-layout-header), .layout-demo :deep(.arco-layout-footer), .layout-demo :deep(.arco-layout-sider-children), .layout-demo :deep(.arco-layout-content) { display: flex; flex-direction: column; justify-content: center; color: var(--color-white); font-size: 16px; font-stretch: condensed; text-align: center; } .layout-demo :deep(.arco-layout-header), .layout-demo :deep(.arco-layout-footer) { height: 64px; background-color: var(--color-primary-light-4); } .layout-demo :deep(.arco-layout-sider) { width: 206px; background-color: var(--color-primary-light-3); } .layout-demo :deep(.arco-layout-content) { background-color: rgb(var(--arcoblue-6)); } </style>
然后我们改一下index.js文件(将GlobalPage引入)(要是看着那些注解感觉不美观的话就直接删了)
import { createRouter, createWebHashHistory } from 'vue-router' import MainPage from '../components/GlobalPage.vue' const routes = [ // { // path: '/', // name: 'home', // component: HomeView // }, // { // path: '/about', // name: 'about', // // route level code-splitting // // this generates a separate chunk (about.[hash].js) for this route // // which is lazy-loaded when the route is visited. // component: () => import(/* webpackChunkName: "about" */ '../views/AboutView.vue') // } { path: '/', name: 'mainPage', component: MainPage } ] const router = createRouter({ history: createWebHashHistory(), routes }) export default router
运行一手看看(记得每次有一些大改就要看看情况,改多再看就会很麻烦,bug也不好排查)
运行出来就是这么个界面
搭建Header和Footer代码
先把头部和尾部的代码解决了。
先来尾部吧,我觉得这个比较简单(哈)
一般来说,网站的底部都是一些网站运营的介绍什么的(大多都是哈,也不一定全是)
这里我就以大家都爱的4399为例(大多都是哈,也不一定全是,哈哈哈)
emmm,这里我们可以把Footer这一块封装为一个组件,因为虽然定义的GlobalPage属于是全局的页面,但万一之后会跳转到其他的页面呢,这里我觉得封装成组件更好一些(看起来也更轻巧一些)
在views目录下创建GlobalFooter.vue
<template> <div id="header">由Heath ceTide 创作的网站 XXX 有限公司</div> </template> <script> export default {}; </script> <style> #header { font-family: "Satisfy", cursive; font-size: 16px; color: rgb(102, 149, 164); margin-right: 20px; } </style>
差不多了,将其替换掉GlobalPage的header
<template> <a-layout style="height: 400px;"> <a-layout-header>Header</a-layout-header> <a-layout> <a-layout-sider theme="dark">Sider</a-layout-sider> <a-layout-content>Content</a-layout-content> </a-layout> <a-layout-footer> <global-footer></global-footer> </a-layout-footer> </a-layout> </template> <script> import GlobalFooter from '../views/GlobalFooter.vue' export default { components: { GlobalFooter }, } </script>
展示出了样式就行了,(之后可以美化以下),好,然后我们开始整Header,
这一块导航栏,我觉得吧,还是用组件比较合适(倒不是不会整,毕竟也麻烦,不用自己手敲的绝不自己手敲代码)
就选这个深色模式导航啦,新建GlobalHeader.vue文件把代码用CV大法放进去
<template> <div class="menu-demo"> <a-menu mode="horizontal" theme="dark" :default-selected-keys="['1']"> <a-menu-item key="0" :style="{ padding: 0, marginRight: '38px' }" disabled> <div :style="{ width: '80px', height: '30px', background: 'var(--color-fill-3)', cursor: 'text', }" /> </a-menu-item> <a-menu-item key="1">Home</a-menu-item> <a-menu-item key="2">Solution</a-menu-item> <a-menu-item key="3">Cloud Service</a-menu-item> <a-menu-item key="4">Cooperation</a-menu-item> </a-menu> </div> </template> <style scoped> .menu-demo { box-sizing: border-box; width: 100%; background-color: var(--color-neutral-2); } </style>
<template> <a-layout style="height: 400px"> <a-layout-header><global-header></global-header></a-layout-header> <a-layout> <a-layout-sider theme="dark">Sider</a-layout-sider> <a-layout-content>Content</a-layout-content> </a-layout> <a-layout-footer> <global-footer class="footer"></global-footer> </a-layout-footer> </a-layout> </template> <script> import GlobalFooter from "../views/GlobalFooter.vue"; import GlobalHeader from "../views/GlobalHeader.vue"; export default { components: { GlobalFooter, GlobalHeader }, }; </script> <style scoped> .layout-demo :deep(.arco-layout-header), .layout-demo :deep(.arco-layout-footer), .layout-demo :deep(.arco-layout-sider-children), .layout-demo :deep(.arco-layout-content) { display: flex; flex-direction: column; justify-content: center; color: var(--color-white); font-size: 16px; font-stretch: condensed; text-align: center; } .layout-demo :deep(.arco-layout-header), .layout-demo :deep(.arco-layout-footer) { height: 64px; background-color: var(--color-primary-light-4); } .layout-demo :deep(.arco-layout-sider) { width: 206px; background-color: var(--color-primary-light-3); } .layout-demo :deep(.arco-layout-content) { background-color: rgb(var(--arcoblue-6)); } .footer { background-color: aliceblue; padding: 16px; position: sticky; bottom: 0; left: 0; right: 0; text-align: center; letter-spacing: 3px; } </style>
其实这个空的区域可以加一个logo或者其他什么的
呐,就像这样
OK,目前的页面就是这个样子了;
搭建搜索页面
好的,下面整一个全局的搜索框页面吧
创建一个SearchPage.vue 文件
从组件库中找到一个合适的搜索框
<!--SearchPage.vue代码--> <template> <a-space direction="vertical" size="large"> <a-input-search :style="{ width: '320px' }" placeholder="Please enter something" button-text="Search" search-button /> </a-space> </template> <script> export default {}; </script> <style> </style>
将新组件放到GlobalPage中(暂时的,之后还是要处理路由的)
<template> <a-layout style="height: 400px"> <a-layout-header><global-header></global-header></a-layout-header> <a-layout> <a-layout-sider theme="dark">Sider</a-layout-sider> <a-layout-content><search-page></search-page></a-layout-content> </a-layout> <a-layout-footer> <global-footer class="footer"></global-footer> </a-layout-footer> </a-layout> </template> <script> import GlobalFooter from "../views/GlobalFooter.vue"; import GlobalHeader from "../views/GlobalHeader.vue"; import SearchPage from '../views/SearchPage.vue'; export default { components: { GlobalFooter, GlobalHeader, SearchPage }, }; </script>
现在搜索框就出来了,(这里最右边加了一点点小细节(不重要)之后会把代码发出来)
这里其实可以加一个搜索框等待效果
<template> <div id="search"> <a-space direction="vertical" size="large"> <a-input-search :style="{ width: '320px' }" placeholder="Please enter something" button-text="Search" search-button /> </a-space> <a-space direction="vertical" size="large"> <a-input-search :style="{ width: '320px' }" placeholder="Please enter something" button-text="Search" search-button loading /> </a-space> </div> </template> <script> export default {}; </script> <style> </style>
这里其实是复制了两个搜索框代码,不过另外一个加上了loading属性,这样就能表现出等待中的效果
呐呐呐,就是这样,然后我们再用v-if定义一下它的显示和隐藏就可以了
ok,演示一下:
先设置script 为setup,然后引入ref
<script setup> import {ref} from 'vue';
还记得之前说的三部曲吗: 1.搭建页面(html,css)-> 2.绑定数据与实践 -> 3.调用后端接口)
那我们以及写好了搜索框了,也该进行数据绑定了(这里暂时不进行后端接口调用,(毕竟还没开发))
对于一个组件的显示和隐藏我们直接写
<script setup> import {ref} from 'vue'; const isSearch = ref(false)
然后呢,两个搜索框绑定该属性(一个是isSearch,一个是!isSearch),这样就能保持一个显示,一个隐藏了。那么,如何实现转换呢,平时在搜索的时候,当我们点击了搜索按钮的时候就会出现转换效果,如果网比较好的话,估计也就直接跳转了,(如果网不好的话,搜索框转圈转了一会儿就会恢复原样)
那么,我们定义一个函数,在正常情况下点击搜索的时候触发,转换为搜索中的样式,然后过几秒就恢复原状。
那么开始定义吧;
<script setup> import {ref} from 'vue'; const isSearch = ref(false) const onSearch = () => { isSearch.value = true; setTimeout(() => { isSearch.value = false; }, 5000); }; </script>
这里定义了一个函数,点击之后,isSearch改变,等到五秒之后,值恢复。来试试吧
<template> <div id="search"> <a-space direction="vertical" size="large" v-if="!isSearch"> <a-input-search :style="{ width: '320px' }" placeholder="Please enter something" button-text="Search" search-button @click=onSearch /> </a-space> <a-space direction="vertical" size="large" v-if="isSearch"> <a-input-search :style="{ width: '320px' }" placeholder="Please enter something" button-text="Search" search-button loading /> </a-space> </div> </template> <script setup> import {ref} from 'vue'; const isSearch = ref(false) const onSearch = () => { isSearch.value = true; setTimeout(() => { isSearch.value = false; }, 5000); }; </script>
成功了,那再来完善一下
有搜索框,当然要有显示搜索内容的区域,
再去组件库看看有没有什么合适的
就用这个吧,
<template> <div id="searchPage"> <div class="search"> <a-space direction="vertical" size="large" v-if="!isSearch"> <a-input-search :style="{ width: '620px' }" placeholder="Please enter something" button-text="Search" search-button @click="onSearch" /> </a-space> <a-space direction="vertical" size="large" v-if="isSearch"> <a-input-search :style="{ width: '620px' }" placeholder="Please enter something" button-text="Search" search-button loading /> </a-space> </div> <a-space direction="vertical" size="large"> <a-radio-group v-model="type" type="button"> <a-radio value="line">Line</a-radio> <a-radio value="card">Card</a-radio> <a-radio value="card-gutter">Card Gutter</a-radio> <a-radio value="text">Text</a-radio> <a-radio value="rounded">Rounded</a-radio> <a-radio value="capsule">Capsule</a-radio> </a-radio-group> <a-radio-group v-model="size" type="button"> <a-radio value="mini">Mini</a-radio> <a-radio value="small">Small</a-radio> <a-radio value="medium">Medium</a-radio> <a-radio value="large">Large</a-radio> </a-radio-group> <a-tabs :type="type" :size="size"> <a-tab-pane key="1" title="Tab 1"> Content of Tab Panel 1 </a-tab-pane> <a-tab-pane key="2" title="Tab 2"> Content of Tab Panel 2 </a-tab-pane> <a-tab-pane key="3" title="Tab 3"> Content of Tab Panel 3 </a-tab-pane> </a-tabs> </a-space> </div> </template> <script setup> import { ref } from "vue"; const isSearch = ref(false); const onSearch = () => { isSearch.value = true; setTimeout(() => { isSearch.value = false; }, 5000); }; </script> <style scoped> .search{ margin: 30px auto; } </style>
添加代码并做一些优化
目前就是这个样子了。
emmm,感觉不太对,好像有点快了,要不还是做一个登录注册页面吧。。。
搭建登录注册页面
创建LoginPage.vue
这一块我觉得还挺容易的,先给个示例代码吧
<template> <div class="container"> <div class="login-box"> <!-- Login Form --> <form action=""> <h2>Login</h2> <div class="input-box"> <span class="icon"><i class="fa-solid fa-envelope"></i></span> <input type="email" required placeholder="Email" /> </div> <div class="input-box"> <span class="icon"><i class="fa-solid fa-lock"></i></span> <input type="password" placeholder="Password" required /> </div> <div class="remember-forget"> <label><input type="checkbox" />Remember Me</label> <a href="#">Forgot Password?</a> </div> <button type="submit">Login</button> <div class="register-link"> <a href="#">Don't have an account? Create Now!</a> </div> </form> </div> </div> </template> <script> export default { } </script> <style scoped> * { margin: 0; padding: 0; box-sizing: border-box; font-family: "Poppins", sans-serif; } .container { width: 100%; height: 100vh; background: url("../assets/background.jpg") no-repeat; background-size: cover; background-position: center; display: flex; justify-content: center; align-items: center; } .container .login-box { position: relative; width: 390px; height: 420px; background-color: transparent; border: 2px solid rgba(255, 255, 255, 0.5); border-radius: 20px; display: flex; justify-content: center; align-items: center; backdrop-filter: blur(15px); } .login-box h2 { font-size: 28px; color: #fff; text-align: center; } .login-box .input-box { position: relative; width: 310px; margin: 30px 0; border-bottom: 2px solid #fff; } .input-box input { width: 100%; height: 50px; background: transparent; border: none; outline: none; font-size: 16px; color: #fff; padding: 0 35px 0 5px; } .input-box input::placeholder { color: #f9f9f9; } .input-box .icon { position: absolute; right: 8px; color: #fff; font-size: 18px; line-height: 50px; } .login-box .remember-forget { margin: -15px 0 15px; font-size: 15px; color: #fff; display: flex; justify-content: space-between; } .remember-forget label input { margin-right: 3px; } .login-box button { width: 100%; height: 40px; background: #fff; border: none; outline: none; border-radius: 40px; cursor: pointer; font-size: 16px; color: #000; transition: all 0.5s; } .login-box button:hover { background: #1f73c9; color: #fff; } .login-box .register-link { font-size: 15px; color: #fff; text-align: center; margin: 20px 0 10px; } .remember-forget a, .register-link a { color: #fff; text-decoration: none; } .remember-forget a:hover, .register-link a:hover { text-decoration: underline; } /* Responsive Design */ @media (max-width: 460px) { .container .login-box { width: 350px; } .login-box .input-box { width: 290px; } } @media (max-width: 360px) { .container .login-box { width: 100%; height: 100vh; border: none; } } </style>
这一块代码是之前找到的一个登录页代码,我觉着就还挺好
不过吧,我决定还是不用这个代码,去组件库上找找吧(主要还是要加深一下组件库的使用)
好了就用这个
小改一下吧;
<template> <div class="container"> <div class="login-box"> <a-form :model="form" :style="{ width: '600px' }" @submit="handleSubmit" class="input-box" > <h2 style="margin-bottom: 60px">Login</h2> <a-form-item field="name" tooltip="Please enter username" label="账号" class="element" > <a-input v-model="form.name" placeholder="please enter your username..." style="margin-right: 40px" /> </a-form-item> <a-form-item field="post" label="密码" class="element"> <a-input v-model="form.post" placeholder="please enter your password..." style="margin-right: 40px" /> </a-form-item> <a-form-item field="isRead"> <a-checkbox v-model="form.isRead"> I have read the manual </a-checkbox> </a-form-item> <a-form-item> <a-button html-type="submit" class="input-box">Submit</a-button> </a-form-item> <div class="register-link"> <a href="#">Don't have an account?

emmm,这代码可谓一坨(发出来也需要些勇气啊。。)
大家如果有自己的写的规范代码就用自己的(hhh)
那么,我们开始前面的三部曲:搭建页面以及完成,可以开始绑定数据与事件了。
<script setup> import {ref} from 'vue'; const loginData = ref({ username: '', password: '', isRead: false, })
先引入ref,然后创建loginData,然后v-model绑定数据
<template> <div class="container"> <div class="login-box"> <a-form :model="loginData" :style="{ width: '600px' }" @submit="handleSubmit" class="input-box" > <h2 style="margin-bottom: 60px">Login</h2> <a-form-item field="name" tooltip="Please enter username" label="账号" class="element" :rules= "rules" > <a-input v-model="loginData.username" placeholder="please enter your username..." style="margin-right: 40px" /> </a-form-item> <a-form-item field="post" label="密码" class="element" :rules= "rules"> <a-input v-model="loginData.password" placeholder="please enter your password..." style="margin-right: 40px" /> </a-form-item> <a-form-item field="isRead"> <a-checkbox v-model="loginData.isRead"> I have read the manual </a-checkbox> </a-form-item> <a-form-item> <a-button html-type="submit" class="input-box">Submit</a-button> </a-form-item> <div class="register-link"> <a href="#">Don't have an account? Create Now!</a> </div> </a-form> </div> </div> </template> <script setup> import {ref} from 'vue'; const loginData = ref({ username: '', password: '', isRead: false, }) const rules = [{ validator: (value, cb) => { return new Promise(resolve => { window.setTimeout(() => { if (value !== ' ') { cb('content not empty') } resolve() }, 1000) }) } }]; </script> <style scoped> * { margin: 0; padding: 0; box-sizing: border-box; font-family: "Poppins", sans-serif; display: flex; justify-content: center; } .container { width: 100%; height: 100vh; background: url("../assets/background.jpg") no-repeat; background-size: cover; background-position: center; display: flex; justify-content: center; align-items: center; } .container .login-box { position: relative; width: 500px; height: 580px; background-color: transparent; border: 2px solid rgba(255, 255, 255, 0.5); border-radius: 20px; display: flex; justify-content: center; align-items: center; backdrop-filter: blur(15px); } .login-box h2 { font-size: 28px; color: #fff; text-align: center; } .login-box .input-box { position: relative; width: 310px; margin: 30px 0; } .input-box input { width: 80%; height: 60px; background: transparent; border: none; outline: none; font-size: 16px; color: #fff; padding: 0 2px 0 5px; } .input-box input::placeholder { color: #f9f9f9; } .input-box .icon { position: absolute; right: 8px; color: #fff; font-size: 16px; line-height: 25px; } .login-box .remember-forget { margin: -15px 0 15px; font-size: 15px; color: #fff; display: flex; justify-content: space-between; } .remember-forget label input { margin-right: 30px; } .login-box button { width: 100%; height: 40px; background: #fff; border: none; outline: none; border-radius: 40px; cursor: pointer; font-size: 16px; color: #000; transition: all 0.5s; } .login-box button:hover { background: #1f73c9; color: #fff; } .login-box .register-link { font-size: 15px; color: #fff; text-align: center; margin: 5px 0 5px; } .remember-forget a, .register-link a { color: #fff; text-decoration: none; } .remember-forget a:hover, .register-link a:hover { text-decoration: underline; } /* Responsive Design */ @media (max-width: 460px) { .container .login-box { width: 350px; } .login-box .input-box { width: 290px; } } @media (max-width: 360px) { .container .login-box { width: 100%; height: 100vh; border: none; } } .element { margin: 20px 0; } </style>
这里可以添加一个校验规则,
在组件库这里找一下表单的校验规则
<script setup> import {ref} from 'vue'; const loginData = ref({ username: '', password: '', isRead: false, }) const rules = [{ validator: (value, cb) => { return new Promise(resolve => { window.setTimeout(() => { if (value === ' ') { cb('content not empty') } resolve() }, 1000) }) } }]; </script>
随便定义了一个,大家可以自己定义看看,(emmm,这里我感觉element-ui的校验规则更好一丢丢)。
好了,既然定义好了登录界面,就可以试试向后端发起请求了。
这里开始在api文件夹下面创建一个文件user.js然后编写一个登录接口函数
import request from '../utils/request' //创建一个调用登录接口函数 export const userLoginService = (loginData) =>{ //用urlSearchParams完成传递 const params = new URLSearchParams() for(let key in loginData){ params.append(key,loginData[key]); } return request.post('/user/login',params); }
定义之后就去登录页调用
<a-form-item> <a-button html-type="submit" class="input-box" @click="login" >Submit</a-button > </a-form-item>
在submit提交这里加上@click="login"
然后定义方法:(获取信息,如果msg提示信息不为0,则显示消息,为0就表示登陆成功)
const login = async()=>{ let result = await userLoginService(loginData.value); alert(result.msg?result.msg:'登录成功'); }
不过,这里用浏览器默认的alert感觉不太美观啊,毕竟都用组件库了,
消息类型:就决定是你了!
引入一手修改代码,
<script setup> import { h } from 'vue'; import { IconExclamationCircleFill } from '@arco-design/web-vue/es/icon'; import { ref } from "vue"; import {userLoginService} from '../api/user' const loginData = ref({ username: "", password: "", isRead: false, }); const rules = [ { validator: (value, cb) => { return new Promise((resolve) => { window.setTimeout(() => { if (value !== " ") { cb("content not empty"); } resolve(); }, 1000); }); }, }, ]; const renderIcon = () => h(IconExclamationCircleFill); const login = async()=>{ let result = await userLoginService(loginData.value); renderIcon(result.msg?result.msg:'登录成功'); } </script>
好,感觉这样也就差不多了,下面展示一下登录页代码
<template> <div class="container"> <div class="login-box"> <a-form :model="loginData" :style="{ width: '600px' }" @submit="handleSubmit" class="input-box" > <h2 style="margin-bottom: 60px">Login</h2> <a-form-item field="name" tooltip="Please enter username" label="账号" class="element" :rules="rules" > <a-input v-model="loginData.username" placeholder="please enter your username..." style="margin-right: 40px" /> </a-form-item> <a-form-item field="post" label="密码" class="element" :rules="rules"> <a-input v-model="loginData.password" placeholder="please enter your password..." style="margin-right: 40px" /> </a-form-item> <a-form-item field="isRead"> <a-checkbox v-model="loginData.isRead"> I have read the manual </a-checkbox> </a-form-item> <a-form-item> <a-button html-type="submit" class="input-box" @click="login" >Submit</a-button > </a-form-item> <div class="register-link"> <a href="#">Don't have an account?

好了,今天的前端就忙碌到这里吧(下一篇文章再见)。
总结一下:1.完成了前端初始化4步,2.完成了全局页面的布局,3.完成了搜索页的代码,和登录页的代码。
