How to use layui connects to the database

layui is an excellent UI framework that provides convenient and fast database connection functions. The following are the steps on how to use layui to connect to the database:

1. Introduce layui

Introduce the layui script into the HTML page:

<script src="layui/layui.js"></script>

2. Introduce the layui module

Use the use method of layui to introduce the database module:

layui.use('form', 'layer', 'table', 'laydate', 'element', 'util', 'laytpl', 'upload', 'layedit', 'laypage', 'flow', 'carousel', 'code', 'jquery', 'cookie', 'exports', 'transfer', 'slider', 'colorpicker', 'tableFilter', 'dropdown', 'widget', 'step', 'progress', 'rate', 'halfpie', 'anim', 'laytpl', 'element', 'slider', 'formSelects', 'moment', 'form', 'tree', 'util', 'layer', 'laydate', 'table');

3. Write the code to connect to the database

layui.use(['jquery'], function () {
    var $ = layui.jquery;
    $.ajax({
        url: '你的数据库连接地址',
        type: 'POST',
        data: {
            username: '你的数据库用户名',
            password: '你的数据库密码',
            database: '你的数据库名称'
        },
        success: function (res) {
            // 连接成功后的处理逻辑
        },
        error: function (err) {
            // 连接失败后的处理逻辑
        }
    });
});

4. Processing the connection results

In the success callback, you can process the logic after the connection is successful, such as displaying the connection results or performing query operations, etc. .

The error callback can handle the logic after the connection fails, such as prompting an error message or retrying the connection, etc.

5. Using the database

Once the connection is successful, you can send SQL queries or update statements through Ajax to operate the database:

$.ajax({
    url: '你的数据库操作地址',
    type: 'POST',
    data: {
        sql: '你的SQL语句'
    },
    success: function (res) {
        // 操作成功后的处理逻辑
    },
    error: function (err) {
        // 操作失败后的处理逻辑
    }
});
