I'm trying to create a form in JavaScript but I can't find the damn form constructor.

Does anyone here know how to create new form objects + hidden fields?

And I don't mean like document.write("<form>");

TIA

code:

---

var form = document.createElement('form');
form.setAttribute('method','post');
form.setAttribute('action','page.php');

var input = document.createElement('input');
input.setAttribute('name','pid');
input.setAttribute('type','hidden');
input.setAttribute('value',pid);

form.appendChild(input);
document.getElementsByTagName('body')[0].appendChild(form);

form.submit();
