How to use Layui to develop a personal information management system that supports editability
Overview:
Personal information management system is a very common application scenario, which can Help users manage their personal information, including basic information, contact information, education experience, work experience, etc. This article will introduce how to use Layui to develop a personal information management system that supports editability, providing users with a convenient and fast information management experience.
- Preparation
First, we need to prepare the development environment. Layui is a front-end framework based on HTML, CSS and JavaScript, so we need to introduce relevant Layui files into the project. You can download the latest version of Layui from the official Layui website (https://www.layui.com/) and extract it to the appropriate location in the project. - Create HTML page
Next, we need to create an HTML page to display personal information and editing functions. For example, we can create an index.html file and add the following code in it:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>个人信息管理系统</title>
<!-- 引入Layui的样式文件 -->
<link rel="stylesheet" href="path/to/layui/css/layui.css">
</head>
<body>
<div class="layui-container">
<h1 id="个人信息">个人信息</h1>
<form class="layui-form">
<div class="layui-form-item">
<label class="layui-form-label">姓名</label>
<div class="layui-input-inline">
<input type="text" name="name" lay-verify="required" autocomplete="off" class="layui-input" value="张三">
</div>
</div>
<div class="layui-form-item">
<label class="layui-form-label">年龄</label>
<div class="layui-input-inline">
<input type="text" name="age" lay-verify="required|number" autocomplete="off" class="layui-input" value="20">
</div>
</div>
<!-- 其他个人信息字段 -->
<div class="layui-form-item">
<div class="layui-input-block">
<button class="layui-btn layui-btn-primary" lay-submit lay-filter="save">保存</button>
</div>
</div>
</form>
</div>
<!-- 引入Layui的JavaScript文件 -->
<script src="path/to/layui/layui.js"></script>
<script>
// 初始化Layui表单组件
layui.use('form', function(){
var form = layui.form;
// 监听表单提交事件
form.on('submit(save)', function(data){
// 提交表单数据到后台进行保存
console.log(data.field);
// ...
return false; // 阻止表单默认提交行为
});
});
</script>
</body>
</html>In the above code, we use Layui's form component to implement the form submission function. The form contains two fields: name and age. You can add other personal information fields according to your needs and set corresponding verification rules.
- Writing the backend interface
In order to save the personal information submitted by the user, we need to write the backend interface to accept the form data and process it. Here we use Node.js and Express.js to implement a simple backend interface. First, we can create an app.js file and add the following code in it:
const express = require('express');
const app = express();
// 接收POST请求体的中间件
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.post('/save', function(req, res) {
console.log(req.body); // 输出表单提交的数据
// TODO: 将表单数据保存到数据库或其他持久化方式
res.json({ message: '保存成功' });
});
app.listen(3000, function() {
console.log('服务器已启动，监听端口3000');
});In the above code, we use express.json() and express.urlencoded() middleware to Parse the data in the POST request body. We created a /save route to receive form data and output it to the console, where you can add corresponding business logic.
- Run the program
Finally, we need to run the program to start the server and access index.html in the browser. You can use the terminal to type the following command to run the program:
node app.js
Then, enter http://localhost:3000 in the browser to access the personal information management system page.
Summary:
Through the above steps, we successfully used Layui to develop a personal information management system that supports editability. Users can edit form data in the browser and save the data to the background via the submit button. You can expand and improve the system according to actual needs, such as adding data verification, data persistence and other functions. Layui provides a wealth of components and tools, providing developers with the ability to quickly build front-end interfaces. I hope this article can provide some help to developers when using Layui to develop personal information management systems.

How layui implements self-adaptation
Apr 26, 2024 am 03:00 AM
Adaptive layout can be achieved by using the responsive layout function of the layui framework. The steps include: referencing the layui framework. Define an adaptive layout container and set the layui-container class. Use responsive breakpoints (xs/sm/md/lg) to hide elements under specific breakpoints. Specify element width using the grid system (layui-col-). Create spacing via offset (layui-offset-). Use responsive utilities (layui-invisible/show/block/inline) to control the visibility of elements and how they appear.
What is the difference between layui and vue?
Apr 04, 2024 am 03:54 AM
The difference between layui and Vue is mainly reflected in functions and concerns. Layui focuses on rapid development of UI elements and provides prefabricated components to simplify page construction; Vue is a full-stack framework that focuses on data binding, component development and state management, and is more suitable for building complex applications. Layui is easy to learn and suitable for quickly building pages; Vue has a steep learning curve but helps build scalable and easy-to-maintain applications. Depending on the project needs and developer skill level, the appropriate framework can be selected.

Apr 04, 2024 am 04:15 AM
Question: Which one is better, layui or ElementUI? Answer: It depends on the project requirements. Layui is more comprehensive, customizable and suitable for large projects, while ElementUI is more lightweight, beautiful and easy to use. The specific reasons for selection are as follows: Choose layui: Provides a wider range of functions and modules that allow a high degree of customization of component appearance and behavior. Suitable for large projects that require a wide range of functions and scalability. Choose ElementUI: Smaller size and faster loading speed. Components follow Material Design principles. , high aesthetics, providing a large number of ready-made components, reducing development complexity and time
