Form input field one after the other

1. I have developed the following form using Bootstrap and have disabled all the input fields except the first input field  by giving a common classname.Now how do i enable them in such a way that after i enter surname i should enter first name after first name last name and so on. Any help would be greatly appreciated . Thanks in advance 

The following is the code which i have used to disable the input fields.

$(document.ready(function() {

$(".disab").attr("disabled",true);

}).
