Here's the simplest equivalent code to do what you want. Use the keydown () method to also check these keys. However, the keypress event is not fired for all keys (e.g. The event occurs when a button is pressed down. The keypress event is similar to the keydown event. Tip: Use the event.which property to return which keyboard key was pressed. The keypress () method triggers the keypress event, or attaches a function to run when a keypress event occurs. The keydown () method triggers the keydown event, or attaches a function to run when a keydown event occurs. Ex: If I keep '9' pressing for a long time, the value in the text box will be '999999999999' but the keyup event is triggered only once. The browser's console window should be showing you errors for these. keyup - The key is released The keydown event occurs when a keyboard key is pressed down. keyup - It is working perfectly for detecting each character entered and appending a hyphen except that 'it will send only a single key entry for a long key press'. Tip: Use the event.which property to return which key was. Your initial function is trying to hook up the event before the element is even defined so that would fail as well. The keyup() method triggers the keyup event, or attaches a function to run when a keyup event occurs. That is causing issues potentially but since you're using Razor I haven't tested it. It can be attached to any element, but the event is only sent to the element. Your HTML is malformed (your GetKey function call is using double quotes inside double quotes). The keyup event is sent to an element when the user releases a key on the keyboard. To detect if the user presses a key, always use the onkeydown event. It is not fired for all keys (like ALT, CTRL, SHIFT, ESC) in all browsers. Keyboard Events See Also: The Keyboard Event Object Warning The onkeypress event is deprecated.

Returns a string representing a locale string indicating the locale the keyboard is configured for. Returns a string representing the key value of the key represented by the event. Returns a boolean value that is true if the event is fired between after compositionstart and before compositionend. Returns a boolean value that is true if the Ctrl key was active when the key event was generated. If you want to display the correct keystrokes to the user, you can use Keyboard.getLayoutMap(). Warning: This ignores the user's keyboard layout, so that if the user presses the key at the "Y" position in a QWERTY keyboard layout (near the middle of the row above the home row), this will always return "KeyY", even if the user has a QWERTZ keyboard (which would mean the user expects a "Z" and all the other properties would indicate a "Z") or a Dvorak keyboard layout (where the user would expect an "F").
