Hi Experts,

I copied the sample code below from a related question the knowledgebase....

Is there any way, I can get the error message from the javascript to display in the html form itself, below the first name, last name and phone number? If so, can you provide the modified logic to the sample below?

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript"><!--
function validate(f)
{
	var err={};
	
	if( f.fname.value=="")
	{
		err.message="Missing First Name";
		err.field=f.fname;
	}
	else if( f.lname.value=="")
	{
		err.message="Missing Last Name";
		err.field=f.lname;
		
	}
	else if( f.phone.value=="")
	{
		err.message="Missing Phone Number";
		err.field=f.phone;
	}
	if(err.message)
	{
		alert(err.message);
		err.field.focus();
		return false;
	}
return true;
}
//--></script>
</head>
<body>
<form action="https://www.someserver.com/file?encoding=UTF-8" method="POST" onsubmit="return validate(this);">
    <input id="fname" name="fname" type="text" value="" />
    <input id="lname" name="lname" type="text" value="" />
    <input id="phone" name="phone" type="text" value="" />
    <input id="submit" name="Submit" type="submit" value="Submit" />
</form> 
</body>
</html>

Yes, simply add e.g. a DIV below the form and assign to it the error message:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript"><!--
function validate(f)
{
        var err={};
        
        if( f.fname.value=="")
        {
                err.message="Missing First Name";
                err.field=f.fname;
        }
        else if( f.lname.value=="")
        {
                err.message="Missing Last Name";
                err.field=f.lname;
                
        }
        else if( f.phone.value=="")
        {
                err.message="Missing Phone Number";
                err.field=f.phone;
        }
        if(err.message)
        {
                document.getElementById('divError').innerHTML = err.message;
                err.field.focus();
                return false;
        }
return true;
}
//--></script>
</head>
<body>
<form action="https://www.someserver.com/file?encoding=UTF-8" method="POST" onsubmit="return validate(this);">
    <input id="fname" name="fname" type="text" value="" />
    <input id="lname" name="lname" type="text" value="" />
    <input id="phone" name="phone" type="text" value="" />
    <input id="submit" name="Submit" type="submit" value="Submit" />
</form>
<div id="divError"></div>
</body>
</html>

And choose a CSS class name that makes the messages stand out.
