Layui is a front-end UI framework used for building the front end of web interfaces, while the back end refers to the server-side program responsible for handling business logic and data interaction. To connect Layui to the back end, data exchange and communication need to be established through various methods.

Here are several common methods for connecting Layui with the backend:

  1. Ajax request: Utilizing the Ajax feature of Layui, you can interact with the backend by sending HTTP requests. The backend can receive the requests and return the corresponding data. For example, you can use Layui’s table module to display and edit table data, sending Ajax requests to the backend for operations such as retrieving data, adding, modifying, or deleting.
  2. The backend provides RESTful API interfaces, and the frontend utilizes Ajax requests from Layui to interact with these interfaces for data exchange. RESTful API is a design style that uses unified URLs and HTTP methods (GET, POST, PUT, DELETE, etc.) to manipulate resources. For example, the frontend can submit form data using the Layui form module and then use Ajax requests to call the backend API for saving or updating operations.
  3. WebSocket is a bidirectional communication protocol that allows for the establishment of a persistent connection between browsers and servers, enabling real-time data transmission. Front-end developers can utilize the WebSocket module in Layui to communicate in real-time with the back-end. For example, in a chat application, the front-end can establish a WebSocket connection with the back-end to send and receive messages in real time.
  4. WebSockets + STOMP: STOMP is a simple messaging protocol that can provide a message-based communication mechanism on top of WebSocket. Front-end can use the WebSocket module of Layui combined with STOMP to send messages to the backend. For example, the layim module of Layui can be used to implement online chat functionality, sending and receiving messages with the backend using WebSocket and STOMP protocols.

Depending on the specific situation, it is necessary to choose a suitable way to connect Layui with the backend. In general, there needs to be an agreement between the frontend and backend on data format, interface design, and communication protocols in order to achieve data transmission and interaction.
