There's an options property on the dropdown object. An example of how
to
set the text of an option:
function changeText()
{
var x=document.getElementById("mySelect");
x.options[x.selectedIndex].text="Melon";
}

Hmmm, all you're wanting is to access the selected index; this example
works for me, click the button it shows the currently selected index on
the client-side (create a file called SelectedIndex.aspx, here's the code):
<%@ Page Language="C#" %>
<HTML>
<HEAD>
<script language="javascript">
function CheckVals()
{
var x = document.getElementById("mySelect");
alert (x.selectedIndex);
}
</script>
</HEAD>
<body>
<form id="form1" runat="server" action="SelectedIndex.aspx"
method="post">
<asp:DropDownList id="mySelect" runat="server">
<asp:ListItem Value="1">1</asp:ListItem>
<asp:ListItem Value="2">2</asp:ListItem>
<asp:ListItem Value="3" Selected="True">3</asp:ListItem>
<asp:ListItem Value="4">4</asp:ListItem>
</asp:DropDownList>
<input type="button" id="button1" onclick="CheckVals();"
value="selIndex"/>
</form>
</body>
</HTML>
