Here is some code to create your input box:
var element = document.createElement('input');
element.type = 'hidden';
element.value = '';
element.id = '';
To add it to a <form> with id="myform" you could do this:
var myform = document.getElementById('myform');
myform.appendChild(element);
FYI: Your <input> doesn't have a name attribute. If you're planning on submitting it as part of a form and processing it on the server side, you should probably include one.

Using DOM methods:
var input = document.createElement("input");
input.setAttribute("type", "hidden");
input.setAttribute("value", "");
input.setAttribute("id", "");
document.getElementById("the-form-id").appendChild(input);

Empty values, here, are equal to not setting them, so i won't:
var input = document.createElement('input');
input.type = 'hidden';
document.body.appendChild(input); // or append it anywhere else...

var inputTag = document.createElement("input");
inputTag.type = "hidden";
It's not necessary to set the other two properties since they would start as nothing anyway.
