javascript error: "Object required"

[Phil]

Hi,

This code gives an javascript error: "Object required" and never let see the
Alert window.
in code-behind:

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Button1.Click
Hiddenfield1.value="end text"
end sub

in aspx file:

<asp:HiddenField ID="hd1" runat="server" value="beginning
text"></asp:HiddenField>
<asp:Button ID="Button1" OnClientClick="test()" runat="server"/>

<script language="javascript" type="text/javascript">
function test()
{
var x = document.getElementById("hd1").value
alert(x)
}
</script>

Thanks
Phil

Is the hd1 a part of any template or a content page or a user control? In
this case it will have a different id on the client. In any case you can
view the html source and check the actual id.

var x = document.getElementById("hd1").value

var x = document.getElementById("hd1").value

var x = document.getElementById("hd1").value

var x = document.getElementById('<%=hd1.ClientID%>').value;
