Answer 1

As simple as this. Can use a simple if statement if you are going to deal with multiple numbers.

    YourVariable = YourVariable.replace(/(\d{1})(\d{3})(\d{3})(\d{4})/, "+$1 ($2)-$3-$4"); 

Displays: +1 (800)-555-5555

    YourVariable = YourVariable.replace(/(\d{3})(\d{3})(\d{4})/, "($1)-$2-$3"); 

Displays (555)-555-5555

If statement (my own code):

if (form.FaxNumber.length = 11){
    form.FaxNumber.value = form.FaxNumber.value.replace(/(\d{1})(\d{3})(\d{3})(\d{4})/, "+$1 ($2)-$3-$4");
}
if (form.FaxNumber.length = 10){
    form.FaxNumber.value = form.FaxNumber.value.replace(/(\d{3})(\d{3})(\d{4})/, "($1)-$2-$3");
}
