bodyhtmlI tried to use something similar to that to get a value out of a text box, but get "document.getElementById('tbDescription') has no properties" in FireFox and "object required" in IE.
[code]
< asp:TextBox id="tbDescription" runat="server" Height="78px" TextMode="MultiLine" onkeypress="check()" Width="363px"></asp:TextBox>
<asp:RequiredFieldValidator id="rfvDescription" EnableClientScript="true" runat="server" ControlToValidate="tbDescription"
Display="none" ErrorMessage="You must give a description of your shipment." Font-Bold="True"
SetFocusOnError="True" ValidationGroup="quickQuote"></asp:RequiredFieldValidator>
<cc1:ValidatorCalloutExtender id="co_rfvDescription" runat="server" TargetControlID="rfvDescription"></cc1:ValidatorCalloutExtender>
[/code]
Javascript Function
[code]
<script language="javascript" type="text/javascript">
function check()
{
var x = document.getElementById('tbDescription').value;
alert(x);
}
</script>
[/code]
