Tryit Editor v2.3

Edit This Code:
<!DOCTYPE html> <html> <body> <p>Press a key on the keyboard in the input field to get the Unicode character code of the pressed key.</p> <input type="text" size="40" onkeypress="myFunction(event)"> <p id="demo"></p> <script> /* In this example, we use a cross-browser solution, because the keyCode property does not work on the onkeypress event in Firefox. However, the which property does. Explanation of the first line in the function below: if the browser supports event.which, then use event.which, otherwise use event.keyCode */ function myFunction(event) { var x = event.which || event.keyCode; document.getElementById("demo").innerHTML = "The Unicode value is: " + x; } </script> </body> <!-- Mirrored from www.w3schools.com/jsref/tryit.asp?filename=tryjsref_event_key_keycode by HTTrack Website Copier/3.x [XR&CO'2014], Fri, 23 Jan 2015 08:30:42 GMT --> </html>
