JavaScript Trigger a button on ENTER key
To trigger a click button on ENTER key, We can use any of the keyup(), keydown() and keypress() events of jQuery.
keyup(): This event occurs when a keyboard key is released. The method either triggers the keyup event, or runs a function when a keyup event occurs.
Syntax:
It triggers the keyup event for the selected element.
$(selector).keyup()
It Attaches a function to the keyup event.
$(selector).keyup(function)
keydown(): This event occurs when a keyboard key is pressed. The method either triggers the keydown event, or to run a function when a keydown event occurs.
Syntax:
It triggers the keydown event for the selected element.
$(selector).keydown()
It Attaches a function to the keydown event.
$(selector).keydown(function)
keypress(): This event is similar to keydown event. This event occurs when a keyboard key is released. The method either triggers the keypress event or runs a function when a keypress event occurs.
Note: This event is not fired for all keys (e.g. ALT, CTRL, SHIFT, ESC).
Syntax:
It triggers the keypress event for the selected element.
$(selector).keypress()
It Attaches a function to the keypress event.
$(selector).keypress(function)
