Get the Unicode value of the pressed keyboard key:
<!DOCTYPE html> <html> <body> <input type="text" size="40" onkeypress="myFunction(event)"> <p id="demo"></p> <script> function myFunction(event) {/*w w w . j av a 2 s. c o m*/ var x = event.charCode; document.getElementById("demo").innerHTML = "The Unicode value is: " + x; } </script> </body> </html>
The charCode property returns the Unicode character code of the key that triggered the onkeypress event.
To convert the Unicode value into a character, use the fromCharCode()
method.
If this property is used on onkeydown or onkeyup events, the returned value is always "0".
This property is read-only.
