How to use the Layui framework to develop a news reading application that supports instant news push

With the rapid development of the Internet, the way people obtain information is also constantly evolving. As a simple and efficient front-end development framework, Layui has been widely recognized and used among developers. This article will introduce how to use the Layui framework to develop a news reading application that supports instant news push, and provide corresponding code examples.

1. Preparatory work
   Before you start, make sure you have successfully installed the browser and Node.js. Then, use the npm command to install layui globally:

npm install layui -g

After the installation is complete, you can use thelayui -Vcommand to check the version information of Layui.

2. Create the project and import Layui
   Create a new folder in the specified directory as the root directory of the project. Then, create the index.html file in this directory and import Layui’s core style and script files:

In the above code, you need to changepath/to/layuiReplace with the path where the actual Layui framework is located. If you place the Layui framework directly in the same directory as index.html, you can set the path directly to./layui.

3. Create News List
   At themark of the page, we will create a simple news list for display The title and brief content of the news. First, import the list module provided by Layui and use this module to create a ul element:

Then, after the page is loaded, use Ajax to request the background interface to obtain news data and dynamically generate list items :

layui.use(['element', 'jquery', 'layer'], function(){ var element = layui.element; var $ = layui.$; $(function(){ $.ajax({ url: '/api/getNewsList', success: function(data){ var newsList = $('#newsList'); for(var i in data){ var newsItem = $('
'); newsItem.append(''); var content = $('
'); content.append('
'+data[i].title+'
'); content.append('
'+data[i].summary+'
'); newsItem.append(content); newsList.append(newsItem); } element.render('timeline'); }, error: function(){ layer.msg('获取新闻列表失败'); } }); }); });

In the above code,/api/getNewsListis the path of a background interface used to obtain news data. You can modify this path according to the specific situation.

4. Implementing the news push function
   Before implementing the instant news push function, we need to introduce the Layim module and modify the index.html file:

In the above code ,path/to/layui/module/is the directory where the Layim module is located. You need to modify it according to the actual situation.

5. Summary
   This article introduces how to use the Layui framework to develop a news reading application that supports instant news push. By introducing related modules of Layui, we can quickly build a concise and efficient front-end page, and interact with the back-end interface for data to realize news display and push functions. I hope this article will be helpful to you in developing a news reading application using Layui.
