Forms lack basic functionality

[alejsanc]

As I have expressed in some proposals that I have sent, the forms have very little functionality, they have hardly evolved and it would be necessary to carry out a study on their present and future.

Form submission in the background without Javascript

Form submission does not show progress

Form not submitted warning message before unload

Form submission confirmation without Javascript

Change form "action" attribute to "target" and add "action" attribute to buttons

Groups of inputs and arrays of groups of inputs in forms

Add boolean input element with "true" and "false" values

Null value in file input

Add method to reset file input and show file size and image/video/audio preview

Add "type" attribute to "textarea" element

Change URL parameter without Javascript or Add a new element to change a URL parameter without Javascript

Searchable dynamic datalist with JSON list without Javascript

Add a new input type for verification codes

Thanks @alejsanc. This seems to be a round-up of proposals, rather than a proposal in its own right, so we're closing it here.

Thanks @alejsanc. This seems to be a round-up of proposals, rather than a proposal in its own right, so we're closing it here.

This is a proposal to make an extensive and necessary evolution of the forms. Each of the proposals included is a part of this evolution. All proposals are related and must be studied together. That is why this proposal that brings them together makes sense.
