How to Make an AJAX POST Request With jQuery
Introduction
AJAX (Asynchronous JavaScript and XML) is a technique for making asynchronous HTTP requests to a server, and handling the response without reloading the entire page. One of the most common types of AJAX requests is a POST request, which is used to send data to a server.
Using the jQuery .post() Method
jQuery provides a simple and convenient way to make AJAX POST requests using the
$.post() method. The syntax for
$.post() is as follows:
$.post(url, data, success, dataType) *
url: The URL of the server-side script that will handle the POST request. *
data: The data to be sent to the server. This can be a plain object, an array, or a string. *
success: A callback function that will be executed if the request is successful. The function will receive the response from the server as its first argument. *
dataType: The expected data type of the response from the server. This can be "text", "html", "json", or "xml".
Example
The following example shows how to use the
$.post() method to send a POST request to a server-side script that will echo back the data that was sent:
In this example, the
#submit button is clicked, the data from the
#name and
#email input fields is collected, and a POST request is made to the
submit.php script. The
submit.php script should echo back the data that was sent to it.
Conclusion
The jQuery
$.post() method is a simple and convenient way to make AJAX POST requests. By using
$.post(), you can easily send data to a server without reloading the entire page.
