Although this is a JavaScript question (OT) not a CF question. you might
want to try
oldvalue = eval("document."+FormName+"."+FieldName+".value")

Subject: Setting form var with Java
Sent this once already but have not gotten any replies, can anyone help?
A little help please. I am trying to use some javascript on my CF pages. I
would like to pass the formname and fieldname to the function, perform an
action and return the value: i.e.
<SCRIPT LANGUAGE = "JavaScript">
<!--
function changevalue(FormName, FieldName)
{
var oldvalue;
var newvalue;
oldvalue = document.FormName.FieldName.value;
TAKE ACTION HERE
document.FormName.FieldName.value = newvalue;
}
//-->
</SCRIPT>
The formname and Fieldnames are being passed fine, but how do I use them.
now oldvalue is being set EQ to "document.FormName.FieldName.value" not the
value of the field , how can I get the value from the form field.
If I call the formfield in the function by hardcoding its name I get the
function to work fine, but I would like to re-use this without having to
change the function each time.
Thanks for your help
Rodney
