ASP how to validate data entry ?

Hi, there.
Below are the simple coding which can validate 2 columns which are Cardno and
Remarks on the same form called "manual_form.
<table width="780" border="0" cellspacing="0" cellpadding="0" ALIGN="Center"> <form action="manual_main2.asp" METHOD="post" onsubmit="return checkform()" name="manual_form"> <input TYPE="Text" size="50" name="CardNo" value="<%= contentEMP("Name")%>" readonly="True" style="background-color:#FFFFCC" ID="Text4"> <script language="JavaScript" type="text/javascript"> function checkform() { var y = document.manual_form.CardNo.value; //alert(y); if (y==""){ alert("Please select Name"); return false; } var x = document.forms["manual_form"]["Remarks"].value if (x == null || x == "") { alert("Remarks must be filled in"); return false;} }


Always apply validations on field so that consistent data entry ensures high integrity data.

Happy coding..
