Hi

Thank you so much for your reply..

I tried with what you said.. but it didn't work

I modified trucklist.jsp as follows:

<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
<head>
<script type="text/javascript">
function getSelectedValue() {

var e = document.getElementById("sel_truck");
var strUser = e.options[e.selectedIndex].value;

document.getElementById("hiddenSelectedValue").value = strUser;

}
</script>
</head>
<body>
<s:form>
<s:select list="truckList" headerKey="1" name="sel_truck"
id="sel_truck" onchange="getSelectedValue()"></s:select>
<input type="hidden" id="hiddenSelectedValue"
name="formHiddenFieldValue" />

</s:form>
</body>
</html>

It didnt give me the expected result. Please let me know if i did it in the correct way.

Thanks and Regards,

Hi all,
I am having two select boxes in my jsp page. I need to populate second select box depending upon the value selected in first select box. I am able to do this. But the problem is i am not getting the value selected in the second select box in the action class. i have provided getters and setters for both select boxes.

The code snippets are given below
