You don't need to disable JavaScript. If you fill out your form you can use JavaScript to submit your form e.g. use runScript and window.document.forms[0].submit().

Whenever you call submit() directly on a form, the form is submitted directly to the server, there is no onsubmit event fired, and therefore, no client-side validation. (Unless your form action is something like javascript:validateForm(), in which case your system doesn't work when JavaScript is disabled).
