You can set a callback function for the onSubmit event of the form and check the contents of each field. If it contains nothing you can then fill it with the string "empty":

and in your js:

function check() {
    if(document.forms["my_form"]["text1"].value == "")
        document.forms["my_form"]["text1"].value = "empty";
}
