I have an image as my button and the form submit and everything, but js is supposed to validate the form before it submits the form.

 

Any ideas on how to fix this?

 

heres my code

Submit button:

<script type="text/javascript">document.write("<input type=\"image\" name=\"Submit\" src=\"img/sendmykit.gif\" onClick=\"check(form,form.elements.length)\" /></script>

 

validation script (this is long):

<!--				

var new_fieldname = ""

function check(form,x)
{
//If you would like to use this script please do not remove the next 4 lines
script_name = "Form Validator ver 2.0"
action =  "Checks Required, Integer and Date"
copyright = "(c) 1998 - Art Lubin / Artswork"
email = "perflunk@aol.com"
var set_up_var = doall(script_name, copyright, email)
var message = ""
var more_message = ""
var showmsg = "no"
if (set_up_var == 5872)
{
	x = x - 1
	for (var i = 0; i <= x; i++)
		{
 			var messenger = form.elements[i].name
			messenger = messenger.substring(0, 2)
			var fieldname = form.elements[i].name
			fieldname = fieldname.substring(2)

				{
					if (messenger == "r_")
						{
							more_message = r_check(form,x,fieldname,i)

			}


	//This code will prevent a submit if data is incoorect
	if (showmsg == "yes")
		{

Use the "onsubmit" trigger in the FORM tag, not the onclick event in your button:

 

Example:

<form name="name" onsubmit="return check(form,form.elements.length);">

 

Also, there is no need to pass "form.elements.length" in the function call - that can be deduced from the form object you are passing.
