How to use the Layui framework to develop a video platform that supports on-demand playback and subscription

In recent years, with the rapid development of the Internet, video platforms have become people’s daily entertainment consumption important way. In order to meet users' needs for on-demand and subscription videos, it is necessary to develop a video platform that supports these two functions. This article will introduce how to use the Layui framework for development and provide specific code examples.

1. Preparation

Before starting development, you need to ensure that Node.js and Layui framework have been installed on the computer. Node.js is a JavaScript running environment that allows you to build a server locally for testing and development. Layui is a front-end UI framework that provides a wealth of components and modules to facilitate developers to build front-end pages.

2. Project structure

First, we need to create a project folder and create the following directory structure under the folder:

css/ to store the project Required CSS style files
js/ Stores JavaScript files required by the project
images/ Stores image files required by the project
index.html Project entry file, user The page displayed when opening the webpage

3. HTML page construction

In the index.html file, introduce the relevant files provided by Layui. It can be introduced through CDN or local path.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>视频平台</title>
    <link rel="stylesheet" href="css/layui.css">
</head>
<body>
    <!-- 页面内容 -->
    <script src="js/layui.js"></script>
    <script src="js/index.js"></script>
</body>
</html>

Build the page layout. Add the layout structure provided by Layui in the body tag, such as:

<body>
    <div class="layui-layout layui-layout-admin">
        <div class="layui-header">
            <!-- 头部内容 -->
        </div>
        <div class="layui-side">
            <!-- 侧边栏内容 -->
        </div>
        <div class="layui-body">
            <!-- 页面主体内容 -->
        </div>
        <div class="layui-footer">
            <!-- 页脚内容 -->
        </div>
    </div>
</body>

Add the main content of the page. In the layui-body tag, you can add components and functions related to instant on-demand and subscription videos. For example:

<div class="layui-body">
    <div class="layui-tab layui-tab-card">
        <ul class="layui-tab-title">
            <li class="layui-this">即时点播</li>
            <li>订阅视频</li>
        </ul>
        <div class="layui-tab-content">
            <div class="layui-tab-item layui-show">
                <!-- 即时点播内容 -->
            </div>
            <div class="layui-tab-item">
                <!-- 订阅视频内容 -->
            </div>
        </div>
    </div>
</div>

4. JavaScript code writing

Create the index.js file in the js folder and introduce the file in index.html.
Write code logic for instant on-demand playback. For example, use Layui's table module to display the video list and add corresponding action buttons.

layui.use('table', function(){
  var table = layui.table;
  
  // 数据加载
  table.render({
    elem: '#videoTable',
    url: '/api/videos', // 请求视频列表的API地址
    cols: [[
      {field: 'title', title: '标题'},
      {field: 'author', title: '作者'},
      {field: 'time', title: '上传时间'},
      {field: 'operation', title: '操作', toolbar:'#videoToolbar'}
    ]]
  });
  
  // 监听工具条
  table.on('tool(videoTable)', function(obj){
    var data = obj.data;
    if(obj.event === 'play'){ // 播放操作
      layer.msg('播放视频：'+ data.title);
    } else if(obj.event === 'download'){ // 下载操作
      layer.msg('下载视频：'+ data.title);
    }
  });
});

Write code logic for subscribing videos. For example, use Layui's form module to submit and save subscription forms.

layui.use('form', function(){
  var form = layui.form;
  
  //监听提交
  form.on('submit(subscribeForm)', function(data){
    layer.msg('订阅成功');
    return false;
  });
});

5. Back-end server development

The back-end server development part is omitted here. You can choose to use Node.js, Java, Python, etc. for development according to the actual situation.

6. Summary

Through the use of the Layui framework, we can easily develop a video platform that supports instant on-demand and subscription. From building the project structure to writing JavaScript code, we gradually completed the development of the video platform. Of course, the above code is just a simple example, and needs to be appropriately adjusted and supplemented according to specific needs during the actual development process. I hope this article can be helpful to students who use the Layui framework to develop video platforms.

The above is the detailed content of How to use the Layui framework to develop a video platform that supports on-demand playback and subscriptions. For more information, please follow other related articles on the PHP Chinese website!
