Jason's Date Input Calendar

Hi, Is it possible to incorporate this script twice in a form and pass the hidden fields without the input buttons
<input type="button" onClick="alert(this.form.orderdate.value)" value="Show date value passed">

I need to process the script with asp and at the moment no fields show in the page code. It is invisible to my asp script at the moment but I dont want those buttons
Its a really nice date calendar.
