Question

This might be a silly question but it is really matter to me to know if we really STILL need to wrap our input elements in side a

even when we are

Answer 1

When using Ajax, the form serves several purposes. It provides:

• a way for the user to submit the data to the server when the JavaScript fails for any reason
• a convenient DOM interface to the controls inside it (formElement.elements.field_id_or_name)
• a semantic grouping that is (for example) used by screen reader software
• handling for the pressing of the enter key to trigger the submit event across all the fields

You don't strictly need it unless you want a robust, accessible, usable page without much more effort.
