[thelist] help with form validation using ASP/VBScript

Tue Mar 1 01:05:23 CST 2005

Brian's approach will not work. Since it is client-side VBScript.

Here is what I will use in such a situation.

<%
Dim IsPostBack = (Request.Form.Count > 0)
Dim field1 = Request.Form("field1")
Dim blnErrorInField1 = False

If IsPostBack Then
	DoValidate
End If

Sub DoValidate
	'any validation logic on form fields.
	If field1.value <> "valid value" Then
		blnErrorInField1 = True
	End If
End Sub
%>
<html>
<head>
	<script type="text/javascript">
		var blnErrorInFied1 = "<%=blnErrorInField1%>";

		window.onload = function(e) {
			if(blnErrorInFied1.toLowerCase() == "true") {
				alert("Error in Field 1");
				document.forms[0].field1.focus();
			}
		}
	</script>
</head>
<body>
	<form id="FrmPage" method="post"
action="<%=Request.ServerVariables("SCRIPT_NAME")%>">
		hello : <input type="text" name="field1" value="" />
	</form>
</body>
</html>

Matt Warden's article given is really nice.

In addition, if possible, consider migrating to ASP.NET, cuz in 2-3
year all the articles you fetch googling will be on ASP.NET.

Volkan.
