篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了基于vue2.0的一个豆瓣电影App相关的知识，希望对你有一定的参考价值。

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)
})
