jQuery Ajax Post Request Example with Parameters


In this tutorial, we will learn how to create AJAX POST requests using jQuery with parameters. This is a common task when working with web applications, as it allows you to send data to a server and receive a response without having to reload the entire page. We’ll create a simple example where we send user input to a server and display the response.

jQuery Ajax Post Request Method Example with Parameters Example

Here is an steps to create jquery ajax post data example with parameters:

Step 1: Create the HTML Structure

Create an HTML file (e.g., index.html) with the following structure:

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>jQuery AJAX POST Example</title>
    <!-- Include jQuery -->
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <h1>jQuery AJAX POST Example</h1>
        <label for="name">Enter your name:</label>
        <input type="text" id="name">
        <button id="submit">Submit</button>
    <div id="result"></div>
    <script src="script.js"></script>

Step 2: Create the JavaScript File

Create a JavaScript file (e.g., script.js) in the same directory as your HTML file. This file will contain the jQuery code to handle the AJAX request:

$(document).ready(function () {
    // When the submit button is clicked
    $("#submit").click(function () {
        // Get the user's input from the input field
        var name = $("#name").val();

        // Create an object with the data to send to the server
        var dataToSend = {
            name: name

        // Send the AJAX POST request
            type: "POST",
            url: "server.php", // Replace with your server-side processing script
            data: dataToSend,
            success: function (response) {
                // Display the response in the result div

In this JavaScript code:

  • We use the $(document).ready() function to ensure that the code runs after the DOM is fully loaded.
  • We attach a click event handler to the “Submit” button.
  • Inside the event handler, we retrieve the user’s input from the input field.
  • We create an object (dataToSend) that contains the data we want to send to the server. In this case, we’re sending the user’s name.
  • We use $.ajax() to make the POST request to the server. Replace "server.php" with the URL of your server-side processing script.
  • In the success callback function, we handle the response from the server by updating the content of the #result div with the response text.

Step 3: Create the Server-Side Script

Create a server-side script (e.g., server.php) to handle the POST request and process the data. Here’s a simple PHP example that just echoes back the received data:

    $name = $_POST["name"];
    echo "Hello, $name!";
} else {
    echo "Invalid request.";

This PHP script checks if the request method is POST, retrieves the name parameter, and echoes a greeting with the received name.

Step 4: Testing the Application

  1. Make sure you have a web server running and serving your HTML and PHP files.
  2. Access the HTML file in your browser.
  3. Enter a name in the input field and click the “Submit” button.
  4. You should see a greeting message displayed in the #result div.
