What Are JavaScript Char Codes?
In JavaScript, a character code represents the numeric Unicode value of a key pressed on the keyboard. For example, the Unicode value 97 represents the lowercase letter “a”.
The charCode property returns the Unicode character code of the key that triggered the keypress event, while keyCode is commonly used with keydown and keyup events.
Cross-Browser Key Code Detection
To ensure compatibility across different browsers, JavaScript developers often use the following fallback approach to detect key values:
This method works reliably in modern and older browsers when capturing keyboard input.
