Hi bcweed
Change your script code like this to get the hiden value..

function getHidVal()
{
hidval = document.getElementById("hid1").value;
alert(hidval )
}

Hope this helps you..

Try this,

<script type="text/javascript">
function findme()
{
    var myhiddenvalue=document.getElementById('<%=hid1.ClientID %>').value;
    alert(myhiddenvalue);
}

</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Finding Hidden Field Value</title>
</head>
<body onload="findme()">
    <form id="form1" runat="server">
    <div>
    <asp:HiddenField ID="hid1" Value="I am Hidden" runat="server" />
    </div>
    </form>
</body>
</html>

The most important thing is

var myhiddenvalue=document.getElementById('<%=hid1.ClientID %>').value;

as <asp:HiddenField > is a server control.

Thanks.

If you are using HTML hidden field like this..

   <input id="hiddenText" type="hidden" name="hiddenText" runat="server" />

you can access it by that ID..like

var parameters= window.document.forms[0].hiddenText.value;

I have a lttle app and i am trying to get to the value of ahiden field on the form thru javascript and i am not expert and much less.

i have this

function TryTest(str) {
Objt = document.getElementById("hid1");
}

i also tryed it like this:

Objt = window.document.getElementById("hid1");

and like that:

Objt = $find('hid1')

but i cant seem to be able to get a Value property from my objt object in my code. What is wrong. Is it because i installed AJAX toolkit?
