I would like to know if it is possible that when submitting the form, an input has an assigned value, specifically the one written above, for example:

I have these inputs:

<form method="POST" name="ing_cod">
  <input type="text" id="code">
  <input type="submit" id="submit">
</form>

And suppose I type the code "123456". Then I press the sumbit and the form is submitted, and when the page refreshes to send another code I want the code entered before to be "123456" in the , Is it possible ?

I tried this:

if(document.ing_cod.submit()){
  var cod = document.querySelector("#code").val()
  document.querySelector("code").val(code)
}

The code sucks, but is there a way to do it? Thanks in advance.
