<script language="JavaScript">
function changeAction(formId, toWhat){
   document.getElementById(formId).dataFld.value = toWhat;
}
</script>

<span id="theForm" datafld="EN"></span></font>

<input type="Button" value="DE" onclick="changeAction('theForm', 'txt/info-DE.txt');">

Statt dataFld, möchte ich :

<object id="TEXT" classid="clsid:333C7BC4-460F-11D0-BC04-0080C7055A83">

<param id="theForm" name="DataURL" value="txt/info.txt"> <-- das hier ändern
<param name="UseHeader" value="true">
<param name="FieldDelim" value="|">
</object>
