[Javascript] coding for the <enter> key

[David T. Lovering]

Assuming that the <enter> key is embedded in the text somewhere in 'var myLine', you could detect it thusly:

  if (myLine.search(/\r/g) != -1) {
    // hey dude, you've got at least one embedded carriage return!
  } else {
    // hey dude, no carriage-returns here
  }

Similarly, if you wanted to whack all the carriage returns in the line, you could do it like this:

  var myLine = myLine.replace(/\r/g, "");

If you wanted to turn them into something visible [like '@' for example], you could do it like this:

  var myLine = myLine.replace(/\r/g, "@");

If you want to detect the incoming characters while they're being typed, you'll have to build an event handler
that traps on the keystroke event from the keyboard.  [Remember, JavaScript is for the most part on the client
end, so this is possible].  However, IE and Netscape use different keycode events, so you'll have to write a
routine that can handle both platforms.
