今天将正式进入Vue项目去哪儿网App开发,下面是Vue项目去哪儿网App开发的准备

码云建立项目
分析HelloVue路由
html代码禁止浏览器缩放网页大小
引入reset.css
引入border.css
vue.js 添加 fastclick的支持
新建Iconfont项目
码云建立项目
关于码云建立项目,这里我PASS。建立完码云项目,直接克隆在本地。
下面就是创建Vue项目,
npm install vue npm install cnpm npm install -g webpack # 安装webpack npm install --global vue-cli # 全局安装脚手架工具 vue init webpack travel# 创建项目(在原有的文件夹中创建,这样可以将名字同步) cd travel npm run dev

新建项目结构如下图:
结构描述如下表:
src核心
src是我们代码编写的核心文件,其内容如下:
assets: 放置一些图片,如logo等。
components: 目录里面放了一个组件文件,可以不用。
App.vue: 项目入口文件,我们也可以直接将组件写这里,而不使用components 目录。
main.js: 项目的核心文件。
分析HelloVue路由
Main.js是项目的入口
import Vue from 'vue'//引入vue.js文件 import App from './App'//引入当前目录下的App.vue文件,【./】指当前目录,【.vue】被隐藏了 import router from './router'//引入当前目录下router文件夹下的Index.js文件 Vue.config.productionTip = false//屏蔽调试时的一些console日志内容 /* eslint-disable no-new */ new Vue({ el: '#app', router,//指定路由的js对象 components: { App },//加载上方导入到组件。 template: '

el:估计是element的缩写,表示Vue绑定的元素。
router:router是我们上面引入的router文件夹下的Index.js文件,打开文件,代码如下:
import Vue from 'vue' import Router from 'vue-router' import HelloWorld from '@/components/HelloWorld' Vue.use(Router) export default new Router({ routes: [ { path: '/', name: 'HelloWorld', component: HelloWorld } ] })

代码中开放了一个默认的Router类型的对象,这个对象是vue-router中定义的,用于定义页面跳转路由,这里定义了路径HelloWorld对应导入/components/HelloWorld.vue文件。
html代码禁止浏览器缩放网页大小
html5默认允许用户缩放页面,如果需要禁止缩放,我们需要在index.html添加minimum-scale=1.0,maximum-scale=1.0,user-scalabel=no

引入reset.css
在HTML标签在浏览器里有默认的样式,例如 p 标签有上下边距,strong标签有字体加粗样式,em标签有字体倾斜样式。因此,需要重置CSS。

引入border.css
该css样式用于解决移动端1像素边框问题。问题分析:有些手机的屏幕分辨率较高,是2-3倍屏幕。css样式中border:1px solid red;在2倍屏下,显示的并不是1个物理像素,而是2个物理像素。为了解决这个问题,引入border.css是非常有必要的。

fastclick:处理移动端click事件300毫秒延迟。
安装:npm install fastclick --sava
之后,在main.js中引入,并绑定到body。
import Vue from 'vue' import App from './App' import router from './router' import fastClick from 'fastclick' import './assets/styles/reset.css' import './assets/styles/border.css' Vue.config.productionTip = false fastClick.attach(document.body) /* eslint-disable no-new */ new Vue({ el: '#app', router, components: { App }, template: '
