How To Set Onclick To Link From Menu Control

I have a content page in which I have set a jsp page using <script> tag. I have created a function to open the page. I need to be able to click the different pages from the menu control.

Code:

<asp:Content
ID="Content1"
ContentPlaceHolderID="menu1"
Runat="Server">
<script
type="text/javascript"
language="javascript">
function openwnd(strId)
{
window.open(s);
var s =
"http://10.7.16.102:8080/src/login.jsp?MainMenuId"
+ strId;
} </script>
<asp:Menu
ID="Menu1"
CssClass="menu"
runat="server"
width="150px"
>
<asp:MenuItem
NavigateUrl="onclick:openwnd('9993');"
Text="part1">
</asp:MenuItem>

When I did the same thing using <a> tag it works fine. but in this case it does not open any page.

Eg: <a
href
="#"
onclick="openwnd('9993');">IIDC</a>
