vue搭配vant组件可以做手机APP界面(vant是业界主流的移动端组件库之一)
我们可以使用vue和组件vant实现简单的登录和注册,下面是我做出来的样子(这是在手机测试的界面)
里面很多组件都是在vant官网上面直接拿来使用的
其中我做了一些小的提示:
1. 登录成功后有“登录成功”提示
2. 未输入用户名和密码会提示“请输入账号或密码”
3. 用户名或密码错误会提示“账号或密码错误”
4. 注册界面,未输入完全信息会提示“注册失败!信息未完善”
5. 注册成功之后有提示“注册成功”,然后上面提示“注册成功,3s后返回登录”,并返回登录页
下面是我们的代码

我的项目文件(实现页面跳转要写好路由)
路由主要写在index.js文件中
index.js
import Vue from 'vue'
import VueRouter from 'vue-router'
import Login from '../views/Login.vue'
import Register from "../views/Register";
Vue.use(VueRouter)
const routes = [
{
path: '/',
name: 'Login',
component: Login
},
{
path: '/register',
name: 'Register',
// 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/Register.vue')
}
]
const router = new VueRouter({
mode: 'history',
base: process.env.BASE_URL,
routes
})
export default router
这里的vant组件是全局引用(可参考vant官网(https://youzan.github.io/vant/#/zh-CN/quickstart)进行引用)
我的vant引用写在了main.js文件中
main.js
import Vue from 'vue'
import App from './App.vue'
import router from './router'
import Vant from 'vant';
import 'vant/lib/index.css';
Vue.use(Vant);
Vue.config.productionTip = false
new Vue({
router,
render: h => h(App)
}).$mount('#app')
以上就是用vue和vant实现的简单的登录和注册界面。
