Set the value of a Javascript input hidden field to that of a value entered in another input text field

I have an input text field (name: qtyText) to which a user enters a value. I would like to set this value as the value for another hidden field (name: qtyTextHidden) using JavaScript. How can I go about it?

HTML

<input name = qtyText type = textbox size = 2 value =  />

<input type=hidden  value =  name=qtyTextHidden/>

My efforts to set the field value using JS work, but I am unable to send the value to the servlet. So I am attempting to directly set the value using a function and then try and send it to the servlet. I would like to have a value = someJSFunction() kind. The function needs to trigger upon onChange in the qtyText input field.

Using jQuery:

$(document).ready(function() {

    $('input:text[name=qtyText]').keyup(function() {

        $('input:hidden[name=qtyTextHidden]').val( $(this).val() );

    });

});

Using JavaScript:

window.onload = function() {

    if(document.readyState == 'complete') {

        document.getElementsByTagName('input')[0].onkeyup = function() {

            document.getElementsByTagName('input')[1].value = this.value;

        };

    }
