jQuery post() method

The post() method is one of the commonly used HTTP methods. It is used to load a page from the server using an HTTP POST request. This method never caches the data and is generally used to send the data with the request. We cannot bookmark the POST requests.

Syntax

Parameter Values

This method includes four parameter values in which one is mandatory, and others are optional. We must have to include the URL parameter to the post() method. The parameter values of the post() method are defined in the following table.

Parameter Values
URL It is the URL to which the request is sent. It is a mandatory parameter.
data It is an optional parameter. It is data sent to the server along with the request.
function(data, status, xhr) This is also an optional parameter. It is a callback function that executes on the successful server request.
It also has three parameters: data, status, and xhr in which data contains the resulting data from the server, status represents the request status like "success", "error", etc., and the xhr contains the XMLHttpRequest object.
dataType This is also an optional parameter that defines the type of data we are expecting from the server. The type can be "text", "json", "jsonp", "html", "script", and "XML".

Now, let's see a simple example of using the post() method.
