                  <soap:Body> \
                        <UpdateListItems xmlns='http://schemas.microsoft.com/sharepoint/soap/'> \
                              <listName>AESO Reports Library</listName> \
                                    <updates> \

Hi,

You can go for this;
<script type="text/javascript">
function show_confirm()
{
var r=confirm(""Do you want to update the item?" ");
if (r==true)
  {
          // Your JS Code
  }
else
  {
  alert("You pressed Cancel!");
  }
}
</script>
