Simple validation question 1

[pgferro]

Hi guys,

I know this sound trivial, but I cannot find a way to do this simple task.

I have a form which is repeated in various pages with different values, and only one text field. In the same page (php) the same form is double, with a different name in case it is an update or a add action in the database.

I have this simple js that I use on an onclick of an image :

<A class="aform" href="javascript: submitform()">
----
function submitform()
{
  document.forms[0].submit();
}
----

Is there a way to validate the single field (whose name changes in several pages) without defining it manually in every page ?

In other word, would it be possible to use something like :

submitform(fieldName)

Thanks !

Sure!

function submitForm(fldName)
{
  var f = document.forms[0];
  var t = f.elements[fldName]; // <-- this is the important bit
  if (t is valid) // add your validation checks here
    f.submit();
  else
    alert("t is not valid!");
}
