To make an ajax request in node.js not obviously how it works, there not exists $_FILE array like in PHP and you have to install a few modules for extracting the passed data.
Types of forms
There could be two type forms, a form that passed files to a server (multipart/form-data) and a form that passes only data.
For the forms with multipart data, we use one of the module formidable or others.
For the forms without multipart we use simply body-parser
Code for sending the ajax request to the server
The code is different for the two types of forms
Code for the forms without sending files
