Enter key event in jQuery

To capture key press event in jQuery we can have key press event and then we can get code of key which is pressed.

Below are few key codes
Enter : 13
Esc    : 27
Space: 32
Tab    : 9

check here for all key codes

Below example will handle the enter and esc key press event  using jquery :

$('#textarea').keyup(function(event){

//use event.which in firefox
var keycode = (event.keyCode ? event.keyCode : event.which);

        alert("Key code for pressed key "+keycode);

       //enter pressed
if(keycode == '13'){
//perform enter key press operation on textarea
}
       //esc pressed
        if(keycode == '27'){
//perform esc key press operation on textarea
}
});
