基于vue2.0的一个豆瓣电影App

1、搭建项目框架

使用vue-cli 没安装的需要先安装

npm intall -g vue-cli

使用vue-cli生成项目框架

vue init webpack-simple vue-movie

然后一路回车

接着进入项目目录

cd vue-movie

然后安装项目依赖包

cnpm install

没安装cnpm的先执行这个命令

npm install -g cnpm --registry=https://registry.npm.taobao.org

接着 npm run dev

看到这个界面说明前面没啥问题了

2、安装需要的依赖包

该项目需要用到vue-router bootstrap

所以先安装这两个包

cnpm install vue-router bootstrap -D

然后在 index.html 页面引用下boostrap.css和另一个需要用到的css文件

　<link rel="stylesheet" href="/node_modules/bootstrap/dist/css/bootstrap.css"><link rel="stylesheet" href="http://v3.bootcss.com/examples/dashboard/dashboard.css">

3、编写代码

App.vue

来到src目录下的App.vue中添加下列代码

<template><div id="app"><nav class="navbar navbar-inverse navbar-fixed-top"><div class="container-fluid"><div class="navbar-header"><button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false"aria-controls="navbar"><span class="sr-only">Toggle navigation</span><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span></button><a class="navbar-brand" href="#">基于Vue2.0的一个豆瓣电影App</a></div><div id="navbar" class="navbar-collapse collapse"><form class="navbar-form navbar-right"><input type="text" class="form-control" placeholder="Search..."></form></div></div></nav><div class="container-fluid"><div class="row"><div class="col-sm-3 col-md-2 sidebar"><ul class="nav nav-sidebar"><li class="active" v-focus="{server:currentRoute}"><router-link to="/in_theaters/0">正在热映</router-link></li><li v-focus="{server:currentRoute}"><router-link to="/coming_soon/0">即将上映</router-link></li><li v-focus="{server:currentRoute}"><router-link to="/top250/0">Top</router-link></li></ul></div><div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main"><router-view></router-view></div></div></div></div></div>
</template>
<script>import jsonp from './js/jsonp.js'import config from './js/config.js'export default {name: 'app',data() {return {currentRoute: '',search: ''}},created() {this.request();},methods: {request() {var server = this.$route.params.server;this.currentRoute = server;},data: {jsondata: {}},Search() {this.$router.push({ path: '/search/0?t=' + this.search, params: { t: this.search } });}},watch: {'$route': 'request'}}

</script>

然后在src目录下新建一个components文件夹

在该文件夹下创建一个movielist.vue

添加以下代码

<template><div><h1 class="page-header">{{jsondata.title}}</h1><ul class="list-group"><li class="list-group-item" v-for="(item,index) in jsondata.subjects"><span class="badge">{{item.rating.average}}</span><div class="media-left"><router-link :to="{path:'/detail/'+item.id}"><img class="media-object" :src="item.images.small" alt=""></router-link></div><div class="media-body"><h3 class="media-heading">{{item.title}}</h3><p><span>类型：</span><span>{{item.genres.join('、')}}</span></p><p><span>导演：</span> <span v-for="(val,index) in item.casts">{{val.name + (index==item.casts.length-1?'':'、')}}</span></p></div></li></ul><div id="layear" v-show="!show"><p>当前第{{parseInt(currentPage) +1}}页、共 {{countPage}}页</p><nav><ul class="pager"><li :class="{disabled:currentPage<=0}"><router-link :to="{path:'/'+server+'/'+ (currentPage<=0?0:(parseInt(currentPage)-1))}">上一页</router-link></li><li :class="{disabled:currentPage>=countPage}"><router-link :to="{path:'/'+server+'/'+(parseInt(currentPage) + parseInt(1))}">下一页</router-link></li></ul></nav></div><div class="spinner" v-show="show"><div class="double-bounce1"></div><div class="double-bounce2"></div></div></div>
</template>
<script>import Vue from 'vue'import jsonp from '../js/jsonp.js'import config from '../js/config.js'export default {created() {this.request();         },data() {return {currentPage: 0,jsondata: {},countPage: 0,server: '',show: 'true'}},methods: {request() {this.show = true;var server = this.$route.params.server;this.server = server;this.currentPage = this.$route.params.page;var count = 10;jsonp(config.apiServer + server, { count: count, start: this.currentPage * count, q: this.$route.query.t }, function (data) {this.jsondata = data;this.countPage = Math.ceil(this.jsondata.total / this.jsondata.count);this.show = false;}.bind(this))}},watch: {'$route.path': 'request','$route.params':'request'}}</script>
<style scoped>.spinner {width: 60px;height: 60px;margin: 100px auto;position: fixed;left: 0;right: 0;top: 0;bottom: 0;}.double-bounce1,.double-bounce2 {width: 100%;height: 100%;border-radius: 50%;background-color: #67CF22;opacity: 0.6;position: absolute;top: 0;left: 0;-webkit-animation: bounce 2.0s infinite ease-in-out;animation: bounce 2.0s infinite ease-in-out;}.double-bounce2 {-webkit-animation-delay: -1.0s;animation-delay: -1.0s;}@-webkit-keyframes bounce {0%,100% {-webkit-transform: scale(0.0)}50% {-webkit-transform: scale(1.0)}}@keyframes bounce {0%,100% {transform: scale(0.0);-webkit-transform: scale(0.0);}50% {transform: scale(1.0);-webkit-transform: scale(1.0);}}
</style>

接着在src目录下创建js文件夹存放js文件

新建一个jsonp.js

var jsonp = function (url, data, callback) {var cbFuncName = 'jsonp_fun' + Math.random().toString().replace('.', '');window[cbFuncName] = callback;var queryString = url.indexOf('?') == -1 ? '?' : '&';for (var key in data) {queryString += key + '=' + data[key] + '&';}queryString += 'callback=' + cbFuncName;var script = document.createElement('script');script.src = url + queryString;document.body.appendChild(script);
}
export default jsonp

在新建一个config.js 用来存放一些配置信息

const apiServer = 'https://api.douban.com/v2/movie/';
export default { apiServer }

接着在新建一个focus.js 用来左边导航栏获取焦点

添加以下代码

import Vue from 'vue'
var focus = {};
focus.install = function () {Vue.directive('focus', function (el, binding) {var server = binding.value.server;var aLink = el.children[0].href;        var link = /^((http)?:\/\/)[\w]+:+[\d]+\/\W+([\w]+)?\/\w/;var val = (aLink.match(link))[3];el.className = '';if (val == server) {el.className = 'active';}})
}
export default focus;

然后来到main.js中引用vue-router 和引用刚才的focus.js和配置vue-router

import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import movielist from './components/movielist.vue'
import focus from './js/focus'Vue.use(VueRouter)
Vue.use(focus)
var routes = [{path: '/:server/:page', component: movielist
},
{ path: '*', redirect:'/in_theaters/0' }]
var router = new VueRouter({routes
})
new Vue({el: '#app',router,render: h => h(App)
})

到这边页面基本成型了

回到命令行继续执行该命令

npm run dev
