Capture DropDown values using EPCF

How would I capture the dropdown box's selected item and pass it on to a java script function that actually raises EPCF.raiseEvent()?

Am using following code:

<script language="javascript">

function raiseEvent()

{

var funcName = htmlb_formid+"_getHtmlbElementId";

func = window[funcName];

var dropdown = eval(func("ddListName"));

var name = dropdown.getValue();

EPCM.raiseEvent("urn:com.epcf.EPCFProducer", "objid",dropdown.getValue());

}

</script>

<hbj:dropdownListBox

id="ddListName" width="150"

model="TESTBEAN.model"

selection="<%=TESTBEAN.getItemText()%>"

onClientSelect="JavaScript:raiseEvent();"

>

</hbj:dropdownListBox>

And in second iView:

<script>

function eventHandler(event)

{

myFormId.data.value=event.dataObject;

}

EPCM.subscribeEvent("urn:com.epcf.EPCFProducer", "objid", eventHandler);

</script>

<form id="myFormId" >

The string passed is:

<input type="text" value="" name="data"/>

</form>

Can anybody correct my code or suggest me appropriateway to do it??
