How to transfer data in layui

The method of using layui to transmit data is as follows: Use Ajax: Create a request object, set the request parameters (URL, method, data), and process the response. Use built-in methods: Simplify data transfer using built-in methods such as $.post, $.get, $.postJSON, or $.getJSON.

How to use layui to transmit data

layui is a powerful front-end framework that provides a simple and easy The method used to transfer data between client and server.

Use Ajax to transmit data

The most common way to use layui to transmit data is to use Ajax. The following are the steps:

1. Create the request object:

   <code class="javascript">var request = $.ajax({
     url: 'url',
     method: 'post',
     data: { ... }
   });</code>

2. Set the request parameters:

   • url: The URL to send the request.
   • method: Request method, such as "get" or "post".
   • data: The data to be sent, which can be an object or a JSON string.

3. Processing the response:

   • request.done(function(response) { ... }) : This function is triggered when the response is successfully received.
   • request.fail(function(xhr, status, error) { ... }): This function is triggered when the request fails.

Use layui’s built-in methods

layui also provides built-in methods to simplify data transmission:

1. $.post(url, data, callback)：Send a POST request and use the callback function to process the response.
2. $.get(url, data, callback)：Send a GET request and use the callback function to handle the response.
3. $.postJSON(url, data, callback): Sends a POST request and automatically converts the data to a JSON string.
4. $.getJSON(url, data, callback): Sends a GET request and automatically converts the response data into a JSON object.

Example: Use layui to transmit JSON data

<code class="javascript">$.ajax({
  url: 'url',
  method: 'post',
  data: JSON.stringify({ ... }),
  contentType: 'application/json'
});</code>

Tips:

• Make sure to use the correct HTTP verb (GET or POST) to send the request.
• The server needs to be configured to process the received data.
• Using layui's built-in methods can simplify the code and reduce errors.
