Question

The javascript event object offers keyCode() and charCode() methods such that charCode() returns 0 for keys that don’t cause a character to be displayed like enter, key up, key down, delete, backspace, etc.

I want to check for exactly these characters inside a jQuery keypress event callback, but the jQuery event object doesn’t give me access to the mentioned methods.

Can I retrieve the js event object from the jQuery one ?

$('#yourid').bind('keypress', function(e) {
    var keycode= (e.keyCode ? e.keyCode : e.which);
        if(keycode == 13){
                // Enter pressed... do anything here...
        }else if(keycode == 46){// delete

        }else if(keycode == 8){ // backspace

        }
});

Explorer doesn’t fire the keypress event for delete, end, enter, escape, function keys, home, insert, pageUp/Down and tab.

If you need to detect these keys, do yourself a favour and search for their keyCode onkeydown/up, and ignore both onkeypress and charCode.
