Changing the charCode of the key pressed

Question

In following example I am attempting to change the charCode of the key pressed but it does not change. When I press "a" I want it to type "b". What am I doing wrong?

$("#target").keypress(function(event) {
     if ( event.which == 97 ) {
         //alert('pressed a');
         //event.preventDefault();
         event.keyCode = 98;
         event.charCode = 98;
         event.which = 98;
     }
});

You can't override the keycode in the event object...

Look at this snippet:

$('#target').keypress(function(e){
    if (e.which == 97)
        this.value = this.value + String.fromCharCode(98)
    else
        this.value = this.value + String.fromCharCode(e.which)

    ....

    return false;
})
