    Safari (Mac) issue

    The following code suppresses the 'enter' key, when run in I.E. 5.5 or
    later (Windows) but not when run in Safari (Mac)

    <body onkeypress="jav ascript:keysupp ress(event)" >

    function keysuppress(e)
    {
    if (e.type=="keypr ess" && e.keyCode=="13" )
    {
    event.returnVal ue=false
    }
    }

    What code can I use to suppress the 'enter' key when running an app in
    Safari?

    Thanks.

      .... or pretty much any non-IE browser.

      Just:
      <body onkeypress="key suppress(event) ">
      You almost never need to write "javascript :" in your pages.
      A better way would be:
      <body onkeypress="ret urn keysuppress(eve nt)">
      Returning false from the handler is the most consistent way of
      stopping an event.

      No need to test the event type when you are only called from an
      "onkeypress " intrinsic event handler - it will be a key press.

      The keyCode is a number, so it would be prettier to compare with the
      number 13 instead of the string "13". And marginally more efficient,
      if it mattered (it doesn't).

      Here you use "event" instead of the variable "e". IE makes the event
      available as the global variable "event", but not all other browsers
      do. The "returnValu e" property of the event is also an IE invention.

      To be consistent with the W3C DOM, you should call the method
      "preventDefault " on the event (but obviously, IE doesn't have one).

      For maximal consistency, you would write:

      if (e.preventDefau lt) {
      e.preventDefaul t();
      } else {
      e.returnValue = false;
      }

      Or, with the addition of the "return" in the handler text above,
      you could just return false:
      ---
      function keysuppress(e) {
      return (e.keyCode != 13);
      }
      ---

      I don't have access to Safari, but I'll be surpriced if this doesn't work.

              ^^^^^^^^^
              Sorry for the public "spelling flame" but since you do not seem to read
              your e-mails: It is _surprised_ and _surprise_. Seems to be a common
              mistake among European students that to not have English as native
              language, especially in Scandinavian countries (from what Google tells me).
