body: <pre><code>&lt;cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" BehaviorID="popup" TargetControlID="cmdTrigger"

                  &lt;asp:Button ID="btnOk" runat="server" Text="Save" Width="48px"   /&gt;
                  &lt;asp:Button ID="btnCancel" runat="server" Text="Cancel" Width="50px" OnClientClick="$find('popup').hide(); return false;" /&gt;

  <p>This is my code. Once I have  written  some thing in textbox  and I click the cancel  button, by which the pop up window  will  close.
  If I try to open the pop up window  again, the textbox will still hold its previous entered value.  so is there any  way I can clear the  value which I have  entered in the textbox,  using Javascript, jQuery.  I don't want to use a  server  side  event  for this  which will  do a post back event so
  what are my options?</p>
