    submitting a page

    I have the following:

    <input type="image" src="images/submit.jpg" width="70" height="30"
    border="0" onclick="valida teRegister()" />

    It is inside a form where:

    <form action="registe r_submit.php" name="register" id="register"
    method="post">

    At the end of validateRegiste r() I have:

    if (msg.length 0) {
    alert(msg);
    } else {
    document.regist er.submit();
    }

    after having built the msg based upon any errors. (It starts with
    var msg = '';)

    What I am happening is that it alerts the message of all the errors
    because msg.length 0, but then it submits the page!!! Even if I
    comment out the document.regist er.submit(), it still submits it.

    How can it submit the page if not a single call is made to post and
    there is not button for submit?

      You have to prevent the default action of the submit event. Methods how
      to do that vary between browsers, one way to do it would be to call the
      ..preventDefaul t() method on the event object where available. Another
      would be to `return false` from the code in the onsubmit attribute.

          Remove the onclick on the image submit.

          Input type="image" is your submit button.

          Your submit button is the input image.

          Javascript validation is only a courtesy to the user, do validate on the
          server.

          Don't worry about people stealing an idea. If it's original, you
          will have to ram it down their throats.

              Uh, no, not the way I had it coded. All it is is a button that invokes
              a javascript. It knows nothing about submitting.

                  How is the default action being invoked? Nothing is labeled "submit"
                  for a type and the submit() is not called.

                      That worked. Thanks.

                              Yes, I just learned this yesterday. I thought that the only submit was
                              through a submit button and that all else was handled by
                              control.submit( ). Thanks.
