How to use the Layui framework to develop a responsive news information website
Introduction:
With the continuous development of the Internet, the way people obtain news information has also changed changed. Nowadays, more and more people use the Internet to browse news and information websites to obtain all kinds of information. In order to meet the needs of users, we need to develop a modern, responsive news and information website. This article will describe how to use the Layui framework to achieve this goal, and provide specific code examples.
1. Introduction to the Layui framework:
Layui is a front-end UI framework based on jQuery, which provides rich components and fine-grained UI control capabilities. The Layui framework has good compatibility, is easy to get started, and supports responsive design, making it very suitable for developing news and information websites.
2. Project setup:
- Prepare the environment: You need to install Node.js and Git to set up the project environment, and then use the npm command to install the Layui framework.
- Initialize the project: Create a new folder and enter the directory on the command line. Then execute the following command:
npm init
npm install layui
Copy after login
- Create HTML file: Create a new HTML file in the project directory and name it index.html. Import the CSS and JS files of the Layui framework in the file. The sample code is as follows:
<!DOCTYPE html>
<html lang="zh-cn">
<head>
<meta charset="UTF-8">
<title>新闻资讯网站</title>
<link rel="stylesheet" href="node_modules/layui-src/dist/css/layui.css">
<script src="node_modules/layui-src/dist/layui.js"></script>
</head>
<body>
<!-- 编写HTML结构 -->
</body>
</html>Copy after login
3. Website layout:
- Navigation bar: Use the nav component of the Layui framework to create a responsive navigation bar. The sample code is as follows:
<div class="layui-nav layui-layout-admin">
<ul class="layui-nav layui-layout-left">
<li class="layui-nav-item layui-this"><a href="">首页</a></li>
<li class="layui-nav-item"><a href="">新闻</a></li>
<li class="layui-nav-item"><a href="">资讯</a></li>
</ul>
</div>Copy after login
- Main content: Use the container component of the Layui framework to create a responsive main content area. The sample code is as follows:
<div class="layui-container">
<!-- 内容区域 -->
</div>Copy after login
4. Dynamic data loading:
- Use Ajax to obtain news data from the backend.
The sample code is as follows:
layui.use('jquery', function(){
var $ = layui.jquery;
$.ajax({
url: 'news_api.php',
type: 'get',
dataType: 'json',
success: function(data){
// 处理数据
},
error: function(){
// 处理错误
}
});
});Copy after login
- Use the template engine laytpl of the Layui framework to render data.
The sample code is as follows:
layui.use(['laytpl'], function(){
var laytpl = layui.laytpl;
var data = [
{title: '新闻标题1', content: '新闻内容1'},
{title: '新闻标题2', content: '新闻内容2'},
{title: '新闻标题3', content: '新闻内容3'}
];
var tpl = document.getElementById('news_template').innerHTML;
laytpl(tpl).render(data, function(html){
document.getElementById('news_list').innerHTML = html;
});
});Copy after login
- Add template and data placement in HTML.
The sample code is as follows:
<script type="text/html" id="news_template">
{{# layui.each(d, function(index, item){ }}
<div class="layui-row">
<div class="layui-col-xs12 layui-col-sm6 layui-col-md4">
<div class="layui-card">
<div class="layui-card-header">{{ item.title }}</div>
<div class="layui-card-body">{{ item.content }}</div>
</div>
</div>
</div>
{{# }); }}
</script>
<div id="news_list"></div>Copy after login
5. Responsive layout:
- Use the grid component of the Layui framework to implement responsive layout by setting different screens Number of columns below to accommodate different devices.
The sample code is as follows:
<div class="layui-row">
<div class="layui-col-xs12 layui-col-sm6 layui-col-md4">
<div class="layui-card">
<div class="layui-card-header">新闻标题1</div>
<div class="layui-card-body">新闻内容1</div>
</div>
</div>
<div class="layui-col-xs12 layui-col-sm6 layui-col-md4">
<div class="layui-card">
<div class="layui-card-header">新闻标题2</div>
<div class="layui-card-body">新闻内容2</div>
</div>
</div>
<div class="layui-col-xs12 layui-col-sm6 layui-col-md4">
<div class="layui-card">
<div class="layui-card-header">新闻标题3</div>
<div class="layui-card-body">新闻内容3</div>
</div>
</div>
</div>Copy after login
- Use media queries to set the number of columns under different screens.
The sample code is as follows:
@media screen and (max-width: 767px){
.layui-col-xs12{
width: 100%;
}
}
@media screen and (min-width: 768px) and (max-width: 991px){
.layui-col-sm6{
width: 50%;
}
}
@media screen and (min-width: 992px){
.layui-col-md4{
width: 33.333333333%;
}
}Copy after login
