let's try this again...

**Golgotha** · Sep 10, 2003, 10:39

what I'm trying to do is if the username is blank then have it alert them to fill it in and give it focus...[THIS WORKS]

but then, I also want it to check the password and make sure it's not null and if it is have it tell them to fill it out and give IT focus.

Code:

 
<%@LANGUAGE="JAVASCRIPT"%>
<%
Session("HandHeldObject")= null
Session("HandHeldObject")= Server.CreateObject("HandHeldItemMaint.HandHeldATL");
Session.Timeout = 300 //5 hours  
var objHandHeld = Session("HandHeldObject");
if (Session("HandHeldObject").Open() == false){ 
%>
<script language="JavaScript">
alert("ERROR: " + "<%=objHandHeld.ErrorMessage%>"); 
</script>
<%
} //<--FROM ABOVE IF
%>

<head>

if( (document.formhandheld.username.value.length <=0) || 
(document.formhandheld.username.value == "") )
 { 
  alert("Enter a usernumber"); 
 document.formhandheld.username.focus(); 
 
 
  var authenticate = true; 
  
   if (authenticate == true) { 
	return false; 
   } 
   else { 
  return true; 
  } 
 }

Try

Code:

<script language="JavaScript"> 
function validate() 
	{
	if((document.formhandheld.username.value.length <=0) || (document.formhandheld.username.value == "" )) 	
		{ 
		alert("Enter a usernumber" ); 
		document.formhandheld.username.focus(); 
		return true; 
		} 
	if((document.formhandheld.password.value.length <=0) || (document.formhandheld.password.value == "" )) 	
		{ 
		alert("Enter a Password" ); 
		document.formhandheld.password.focus(); 
		return true; 
		} 
	return false;
	}
</script>

ahem

</plug>

Now, for the direct answer

Code:

function validate( f )
{ 
	if( ( f.username.value.length <= 0 ) || ( f.username.value == "" ) )
	{ 
		alert( "Enter a usernumber" ); 
		f.username.focus(); 
		return false;
	}
	if ( f.password.value.length <= 0 ) || ( f.password.value == "" ) )
	{
		alert( "Enter a password" );
		f.username.focus();
		return false;
	}
	return true;
}
 
...
 
<form name="formhandheld" action="pocketLogInProcess.asp" method="post" onSubmit="return validate(this)">

There are several refactoring steps that could be taken still, but, this should get you going in the right direction.

**patrikG** · Sep 10, 2003, 11:56

Ah, now that comes from focusing too narrowly on the problem at hand and not checking my code and doing it too quickly

I should have looked at what happens on return false or true...

**Golgotha** · Sep 10, 2003, 12:04

ok that works, but what is they hit spacebar in both fields, then I get an error

**bbolte** · Sep 10, 2003, 12:39

you may have to use a regular expression then. or right a check for spaces, but then you'd have to loop through each character to make sure they didn't hit the spacebar numerous times. look into regular expression, would be more efficient in the long run.

**bbolte** · Sep 10, 2003, 13:46

here's something that may get you started, it won't allow anything in the field except alpha numeric characters. i tested it some, not extensively...

Code:

<html>
<head>
<title>js test</title>
<script language="JavaScript">
function validateForm(){
var str=document.forms[0].textfield.value
var filter=/[a-zA-Z0-9]/
if (!filter.test(str)){
alert("Those aren't the correct characters!" );
document.forms[0].textfield.focus();
return false;
}
else{
alert("Those are correct characters!" );
return true;
}
}
</script>

</head>
<body>
<form action="" onSubmit="return validateForm();">
<input type="text" name="textfield">
<input type="submit" name="submit" value="Test the Field">
</form>
</body>
</html>

**bbolte** · Sep 10, 2003, 13:52

actually, it's not quite right. if you put "1a 433xxx" it still validates. but you can get the drift from this anyway.

**bbolte** · Sep 10, 2003, 13:58

but this pattern seems to work:

Code:

function validateForm(){
 var str=document.forms[0].textfield.value;
 //var filter=/^[a-zA-Z0-9]/;
 var filter=/\W/
 if (filter.test(str)){
  alert("Those aren't the correct characters!")
  document.forms[0].textfield.focus();
  return false;
 }
 else{
  alert("Those are correct characters!");
  document.forms[0].textfield.focus();
  return true;
 }
}

**Golgotha** · Sep 10, 2003, 14:12

I did

Code:

isNaN(parseInt(f.username.value))

and it seems to work

**beetle** · Sep 10, 2003, 14:18

Or, you can use fValidate!

ooh, hadn't thought of that. will have to look into that.

There's an aweful lot of unplugging going on
