set the id of form elements as directed here and
call the CheckEntireForm(objForm) in the form submit evet
i.e. <form onSubmit = "return CheckEntireForm(MyFormName)" ... >

URL-Y/N Validate URL
RQ-Y/N REQUIRED(SHOULD NOT BE BLANK)
NM-Y/N NAME
NU-Y/N NUMERIC
FN-Y/N FLOAT NUMERIC
NUR-Y/N NUMERIC RANGE
NURMX-n MAX NUMERIC RANGE
NURMN-n MIN NUMERIC RANGE
NRC-Y/N CHECK NUMEIC RANGE
PH-Y/N PHONE
EM-Y/N EMAIL
CMX-n CONTROL HAS n AS MAX RANGE
CMN-n CONTROL HAS n AS MIN RANGE
CRC - Y/N CHECK CONTROL LENGTH RANGE
LBC-Y/N- CONTROL IS A LIST BOX CONTROL AND CHECK THAT A SELECTON IS MADE
MSS - XYZ... MESSAGE TO THROW IF VALIDATION FAILED
SPA - Y/N space is not allowed

A SAMPLE ID IS SHOWN HERE
RQ-Y|NU-Y|CMN-3|CMX-8|MSS-EMPLYOEE_INCOME_LEVEL
this field is a required field, it can only accept
numeric data and can contain only 3 to 8 char length number
it is EMPLYOEE INCOME LEVEL (notice underscore as space is not allowwd)
