    retrieving current input field

    Scenario:

    I'm using the following code to avoid that users use the return key in the
    middle of a form to submit the entire form
    ---- snip ---------
    function kH(e) {
    var pK = document.all? window.event.ke yCode:e.which;
    return pK != 13;
    }

    document.onkeyp ress = kH;
    if (document.layer s) document.captur eEvents(Event.K EYPRESS);
    ---- snip ---------

    What I would do is to modify the code so that when the users is in a
    textarea input field they are allowed to use the return key. Is there a
    funcion/method I can use in the function to test in which named input field
    is the active one?

      Curious. Why aren't you using an onsubmit event? Or are you? I don't
      understand why your form is getting submitted when someone presses the
      return key. Is this a self processing form?

          I don't know neither. The code is inherited. Here is a stripped version:
          ---[snip]---

          <%
          response.write( "<html><hea d>")
          response.write( "<title>Testing </title>")
          %>

          <script type="text/javascript">
          function kH(e) {
          var pK = window.event.ke yCode;
          return pK != 13;
          }
          document.onkeyp ress = kH;
          </script>

          <%
          response.write( "</head>")
          response.write( "<body>")
          response.write( "<form action=""showmo del.asp"" name=""dummy"" >")
          response.write( "<br><input name=""a"" type=""text"" autocomplete="" off"" >")
          response.write( "<br><input name=""b"" type=""text"" autocomplete="" off"" >")
          response.write( "<p><input name=""c"" type=""submit"" >")
          response.write( "</form>")
          response.write( "</body>")
          response.write( "</html>")
          %>

          Without the onkeypress handler the form gets submitted when i press return
          in any of the inupt fields

              Here I have a simple fix for you,

              <script>
              function check(cde){
              if(cde == 13){
              event.returnVal ue=false
              }
              }
              </script>

              <body onkeydown="chec k(event.keyCode )">

              This will do the trick, but remember it will TOTALLY disable the enter
              key like previously sugessted maybe try,

              <form onsubmit="check (event.keyCode) ">

              Then you have to submit the form by clicking the submit button.

              Hope this helped.

              Best Regards,

                  Hey
                  Thanks for the advice.
                  BUT - I'm not having any problems in disabling the return key. Works fine
                  with my own code. What I would like to implement is that I want to modify
                  this code, so that when a user is in a textarea they are allowed to use the
                  return key. So my question is:

                  can I modify my code or check() above so I can check in which (input) field
                  the cursor is placed when the key is pressed?
