clientclick to validate server side input

Hi Experts,

I have simple <form id="myform" runat="server" action="#">

<input id="mytxt1" runat="server" />
<input id="mytxt2" runat="server" />

<asp:button id="mybutton" onclick="do_stuff" onclientclick="something">

I need using either jquery or javascript to on clientclick code on client side :

1. get value of mytxt1
2  copy this value to mytxt2

Thanks a lot.

You would need to do something like:
    <form runat="server">

        <input id="mytxt1" runat="server" />
        <input id="mytxt2" runat="server" />

        <asp:Button id="mybutton" runat="server" OnClick="do_stuff" OnClientClick="return something();" Text="Click Me" />


    <script type="text/javascript">
        function something() {
            document.getElementById('<%= mytxt2.ClientID %>').value = document.getElementById('<%= mytxt1.ClientID %>').value;
            return false;

Open in new window

Note: You'll need to take the return false; part out if you want the page to postback. I just added it in to stop the post back so you can see the copy take place.
