Hi ,
what i understand from your original problem is you want to capture on change event
and want a mechanins to idenify each "option" uniquely..right.
Whatever u r doing using struts is correct..and need not to make "indexed=true" .
All you need to do is just write a javascript code some what like this :
<script language="javascript">
function callMe(objSelect){
alert(objSelect); //it should show "[object]" {
function callMe(objSelect){
if(objSelect.option[objSelect.options.selectedIndex].value="a"){
//do this
}else if (objSelect.option[objSelect.options.selectedIndex].value="b"){
//do this;
}
}
}
</script>
<html:form action="\someAction.do" name="myForm" ...... >
<td valign="top">
<html:select name="menuEntries" property="menuAction"
onchange="callMe(window.document.myForm.elements[0])" >
<html:option value="">Select A Action</html:option>
<html:options name="actionNames"
labelName="actionNames"/>
</html:select>
</td>
</html:form>
>No you don't need 11 different methods, if you read through this it
>(hopefully) should be clearer
