I'd like to be able to capture the immediately preceeding keystroke and use it with an onClick (or some appropriate event) with an INPUT statement to keep the user from proceeding if the last character wasn't an ENTER(13).

Thanks

Hi...

Here's a quick HTML file that you can use to see the functionality you're requesting...

<!doctype html public "-//w3c//dtd html 4.0 transitional//en">
<html>
<head>
<title> new document </title>

<script language=JavaScript>

var myKeyCode = '';

function doKeyDown (e) {
    myKeyCode = e.keyCode;
}

function testForEnter() {
      if (myKeyCode != 13) {
            alert("Last keystroke was NOT enter!");
      } else {
            alert("Last keystroke was enter!");
      }
}

</SCRIPT>
</head>

<body onKeyDown="return doKeyDown(event);">
<form name="my_form">
<input type="button" name="the_button" value="test for enter" onclick="testForEnter();">
</form>
</body>
</html>

HTH!
