从零到一，做出一个高仿网易云音乐，可能一些地方会做出样式改动，使之更具个人风格。
由于代码比较多，就不放到这里，有需要的请查看源码
需求图：

整个项目使用模块化与MVC

后台管理页面 pc端

首先制作后台管理页面，上传使用七牛云，数据库使用leancloud，上传和保存数据的问题不做过多赘述，参考官方的文档。

• 在使用七牛的上传功能时，遇到了上传凭证的问题，需要后端返回一个uptoken。
  解决办法：使用node.js造一个本地服务器
• 在模块化的过程中，遇到了模块无法交流的问题，此使用发布订阅模式解决，造出一个事件中心

window.eventHub = {
    events: {},
    emit(eventName, data){  //发布 call函数
        for(let key in this.events){
            if(key === eventName){
                let fnList = this.events[key]
                fnList.map((fn)=>{
                    fn.call(undefined, data)
                })
            }
        }
    },
    on(eventName, callback){  //订阅  push函数
        if(this.events[eventName] === undefined){
            this.events[eventName] = []
        }
        this.events[eventName].push(callback)
    },
}

每个事件对应多个函数，当一个模块发布此事件，会执行其他模块订阅此事件的回调函数。

效果图： 歌曲管理页面

移动端页面

首先分析一下网易云音乐的各个界面

推荐音乐
热歌榜
搜索
ok，我们通过这三张图可以看出这三个界面其实实在一个页面里的，所以说推荐音乐、热歌榜、搜索三个页面的显示只需要通过JS来控制CSS样式就可以做到。

首先我们完成顶部的tab以及推荐音乐界面

顶部tab
分析页面我们首先可以发现这个tab是fixed定位的并且内部有两部分，内部由两部分组成，我们可以用一个父元素包裹两个子元素，并且使用flex布局，就能达到这样的效果。

效果图

ok接下来写推荐音乐页面，我们先将整体的布局做好
HTML:

<!--写在header标签后面！-->
<ol class="all-tab">
  <li class="page-1 acrtive">1</li><!--打开网页后默认显示推荐音乐界面-->
  <li class="page-2">2</li>
  <li class="page-3">3</li>
</ol> 

继续写HTML，写在page-1里面：

<section class="play-list">
                    <span class="special">推荐歌单</span>
                    <div class="play-list-container">
                        <div class="row">

效果图，这是我已经做好的- -

ok，这样子推荐音乐以已经完成，热歌榜和搜索界面我们暂时不做，接下来写JS

使用JS控制tab切换

建立4个JS文件，tab对应一个，三个page分别对应。

请不要忘记引入jQuery

tab.js:

{
    let view = {
        el: '#tabs',
        init(){
            this.$el = $(this.el)
        }
    }
    let model = {}
    let controller = {
        init(view, model){
            this.view = view
            this.view.init()
            this.model = model
            this.bindEvents()
        },
        bindEvents(){
            this.view.$el.on('click', 'li', (e)=>{
                let $li = $(e.currentTarget)
                $li.addClass('active').siblings('.active').removeClass('active')
                let tabName = $li.attr('data-tab-name')
                //通过获取data-tab-name我们就能知道当前所点击的li对应的page，再将tabName通过订阅/发布模式传给订阅这个事件的js
                window.eventHub.emit('select', tabName)
            })
        }
    }
    controller.init(view, model)
}

page-1.js:

//目前三个page的js都这样写，注意改掉page-x！！！
{
    let view = {
        el: '.page-1',
        init(){
            this.$el = $(this.el)
        },
        show(){
            this.$el.addClass('active')
        },
        hide(){
            this.$el.removeClass('active')
        }
    }
    let model = {}
    let controller = {
        init(view, model){
            this.view = view
            this.view.init()
            this.model = model
            this.bindEventHub()
            this.bindEvents()
        },
        bindEvents(){

        },
        bindEventHub(){
            window.eventHub.on('select', (tabName)=>{
                if(tabName === 'page-1'){
                    this.view.show()
                }else{
                    this.view.hide()
                }
            })
        }
    }
    controller.init(view ,model)
}

ok，tab切换已经做好了
