How to convert a char to its keycode?

Question

How can I convert a character to its respective keycode?

For example:

• a to 65
• b to 66
• c to 67
• d to 68

Answer 1

You can use the charCodeAt function to achieve this.

Working example:

function showKeyCode () {      var character = document.getElementById("character").value.substring(0, 1);      var code = document.getElementById("character").value.charCodeAt(0);      var msg = "The Key Code for the \"" + character + "\" character is " + code + ".";      alert(msg);  }

<input type="text" id="character" size="15">  <input type="button" value="Show Key Code" onclick="showKeyCode();">
