This particular event's proper functioning might depend on the
browser as well, have you tried the same with different browsers?

Can you try different external browsers (e.g. Chrome, Firefox, IE) in Eclipse...and see the results...

I tried using both firefox and IE but its still same. I am not sure is this the only way to call javascript function? cause its not going in there!!

HI, I think my problem is total different.

I am posting whole jsp page as such it will extend once I can find combobox's selected value.

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags"%>

<html>
<head>
<title>Feedback Collection System | By Dhaval Tamboli</title>
</head>
<script language="JavaScript" type="text/javascript">
function selfSubmit(){
	System.out.println("Test 1: ");
	document.frmIndex.action="";
	  
	  
	  var cboTestObj = document.getElementById("Question_Type");
	  System.out.println("Hope: "+cboTestObj);
	  document.frmIndex.submit();
}
</script>
<body>
<s:if test="#session.logged-in != true">
<jsp:forward page="/index.jsp" />  
</s:if>
<h2>Create Questionnaire</h2>
<s:actionerror />

<s:form action="addQuestionnaire" method="post">
	<s:textfield name="Question_ID" key="label.Questionid" size="20"/>
	<s:textfield name="Question_Name" key="label.Question" size="20" />
	
	<s:combobox name="Question_Type" key="label.Questiontype" size="20" 
	list="{'Single Select Option','Multiple Select Option','Comment Box','Rating Scale', 'Yes/No'}"
    headerKey="-1"
    headerValue="--- Please Select ---"
    onchange="javascript: selfSubmit();"
	 />
	
	<s:submit method="create" key="label.create" align="right" />
	
</s:form>
</body>
</html>

I tested your code and it functions, but maybe not the way you think it should. If you view the generated HTML code, the onselect event is on the input box. If you select something from the select box and then select the text in the input box the event will fire.

Also, you should be calling alert in your function, not System.out.println.

Hi,

I got your point but I dont know how to see generated html code and also I am confused regarding fetching combobox's value in javascript.

Thanks

You can see generated html code by selecting the View Page Source option in your browser.

You cannot get the selected value in the combo box, you will have to get the value from the text box. If you assign an id to your combo box, the id is assigned to the text box and you can get the value from the text box.
