继续上一篇文章,这次以实际项目为主题。
我们做一个看漫画的APP,名字就叫爱柯南,但是不会只有柯南一个。
首先在components下新建main文件夹,用来存放4个主导航页。
在这个文件夹下新建4个vue文件,分别是Home.vue、News.vue、Classify.vue、Personal.vue,内容都一样
<template> <div> <h1>{{msg}}</h1> <img src="@/static/images/logo.png"> </div> </template> <script> export default { data () { return { msg: "首页" //把这里都改一下 } } } </script> <style scoped> </style>
@这里可以简单地理解为src根路径。
然后修改tool/router/index.js文件
import Vue from 'vue' import Router from 'vue-router' import Home from '@/components/main/Home' import News from '@/components/main/News' import Classify from '@/components/main/Classify' import Personal from '@/components/main/Personal' Vue.use(Router); export default new Router({ routes: [ { path: '/', redirect: '/home' }, { path: '/home', name: 'home', component: Home }, { path: '/news', name: 'news', component: News }, { path: '/classify', name: 'classify', component: Classify }, { path: '/personal', name: 'personal', component: Personal } ] });
然后在components下新建Footer.vue文件,用来处理底部导航
<template> <tabbar @on-index-change="foo"> <tabbar-item selected> <img slot="icon" src="../assets/images/homepage.png"> <img slot="icon-active" src="../assets/images/homepage_fill.png"> <span slot="label">首页</span> </tabbar-item> <tabbar-item> <img slot="icon" src="../assets/images/flashlight.png"> <img slot="icon-active" src="../assets/images/flashlight_fill.png"> <span slot="label">最新</span> </tabbar-item> <tabbar-item> <img slot="icon" src="../assets/images/createtask.png"> <img slot="icon-active" src="../assets/images/createtask_fill.png"> <span slot="label">分类</span> </tabbar-item> <tabbar-item> <img slot="icon" src="../assets/images/people.png"> <img slot="icon-active" src="../assets/images/people_fill.png"> <span slot="label">我的</span> </tabbar-item> </tabbar> </template> <script> import {Tabbar, TabbarItem} from 'vux' import router from '@/tool/router/index.js' export default { name: 'AppFooter', components: { Tabbar, TabbarItem }, methods: { foo: function (newindex, oldindex) { switch (newindex){ case 0 : router.replace('/home'); break; case 1: router.replace('/news'); break; case 2: router.replace('/classify'); break; case 3: router.replace('/personal'); break; } } } } </script> <style> </style>
需要注意的是,我们这里并不采用vux官方API里demo的跳转方式(在TabbarItem上加link),而是用on-index-change事件,在这个事件里我们通过router.replace来切换路由,否则你在多次点击底部导航之后再回退的话,会把前面点过的再回退一遍。
我们再添加几个less样式,来初始化和添加全局样式。
在assets下新建less文件夹,在里面新建
app.less
#app { .weui-tabbar__item.weui-bar__item_on .weui-tabbar__icon, .weui-tabbar__item.weui-bar__item_on .weui-tabbar__icon > i, .weui-tabbar__item.weui-bar__item_on .weui-tabbar__label { color: #1296DB } }
reset.less
button { -webkit-tap-highlight-color: rgba(0, 0, 0, 0); -webkit-appearance: none; padding: 0; margin: 0; outline: none; border: none; border-radius: 0; background: transparent; }
main.less
@import '~vux/src/styles/reset.less'; @import "reset"; @import "app";
然后修改APP.vue文件
<template> <div id="app"> <router-view/> <app-footer></app-footer> </div> </template> <script> import AppFooter from './components/Footer.vue' export default { name: 'app', components: { AppFooter } } </script> <style lang="less"> @import "./assets/less/main.less"; </style>
