How do I pass parameters in window.open method

How do I pass parameters in window.open method.

<table id="tblUsers" cellspacing="0" >
        <asp:Repeater ID="repUsers" runat="server">
        <ItemTemplate>
        <tr><td>&nbsp;<a ID="hlUser" runat="server"  Target="_new"  onclick="return OpenWindow();" ><%# Eval("Username") %></a></td></tr>
        </ItemTemplate>
        </asp:Repeater>
    </table>

function OpenWindow() {
    var toUsername = document.getElementById("hlUser");
    window.open("ChatWindow.aspx?username=" + toUsername.value, "ChatWindow", "width=350,height=250");
    return null;
}

I don't know much about asp.net, but looks like you have a javascript problem. Isn't document.getElementById("hlUser") an <a> element? It has no value attribute.

If you want to get the text element inside the <a> you could query the text property, or innerHTML. 

<a id="hlUser">somevalue</a>

document.getElementById('hlUser').text will return somevalue

UPDATE: Having that <a> inside a repeater makes it impossible to know with confidence any id attribute inside it beforehand. I'd reccomend passing the <a> element, or this.text itself , or even the value using the same server-side script to the function.

UPDATE 2: I see this question might be a duplicate of How do I pass a variable using window.open()?

Just change the & to a +:

function OpenWindow() {
        var toUsername = document.getElementById("hlUser");
        window.open("ChatWindow.aspx?username=" + toUsername.value, "ChatWindow", "width=350,height=250");
        return null;
    }

At this level of code, you're working in Javascript rather than VB, and VB's use of & for concatenation is an oddity among programming languages.
