How to make a form submission without form?

Navigation
2

The question may seem strange. But on a particular page I would like to make a submit , like a form, when clicking a button, but without the presence of the form in HTML.

Is there any way to simulate submitting a form, without it being on the page?

Example: 

<!-- Faz um paranauê para submeter a página via post sem formulário -->
<button id="submit"></button>

Note : I do not need a form fill, or anything. I just need that, when the button is clicked, a form submission is sent (POST method). And it's not an ajax request.

If you just need to send the form, you could use ajax, but it does not seem to be the case, there is still a new html5 attribute that can help you, is form="..." and create a hidden form you will need javascript): 

<!--// formulário oculto -->
<form action="rota" method="POST" id="meuformulario">
  <input type="hidden" name="chave1" value="1">
  <input type="hidden" name="chave2" value="2">
  <input type="hidden" name="chave3" value="3">
</form>

...

<p>....</p>


...    

<button type="submit" form="meuformulario" value="Chamar">Chamar (trigger)</button>

In addition it is still possible to control the form with other attributes by <button> :

  • formaction change the form action pointed to by the form="" attribute

  • formenctype this attribute change the ecntype of the form pointed to by the form="" attribute, values that can be used:

    • application/x-www-form-urlencoded
    • multipart/form-data
    • text/plain

  • formmethod exchange method of <form> pointed to by attribute form=""

Yes, there is a way. You can do the same way you use to submit a form via javascript, however you will only use what is created by document.createElement

So: 

var fake_form = document.createElement('form');

fake_form.method = 'POST';

document.querySelector('#submit').addEventListener('click', function()
{
     fake_form.submit();
});
