In Javascript onkeypress Event,Tab button does not fire(In Mozilla Firefox)

I have a textbox, I need to validate my textbox using onkeypress (to restrict special characters). It works fine in Chrome. In Mozilla Firefox it does not fire (Tab Button). Is there any events to add in my code?

My code:

function alpha(e) {
    var k;
    document.all ? k = e.keyCode : k = e.which;
    return ((k > 64 && k < 91) || (k > 96 && k < 123) || k == 9);   //k=9(keycode for tab)
}

This might help you.

function alpha(e){
    var k = e.charCode ? e.charCode : e.keyCode;
    return ((k > 64 && k < 91) || (k > 96 && k < 123) || k == 9);   //k=9(keycode for tab)
}
