First add dataType:'JSON'

Then add some conditions in success function:

$('.sub').click(function(e) {
var input = $(this);
...
...
$.ajax({
...
success: function(result){
    var status = result.status;
    input.val(status);
    if(status==1){
    //Not logged in
    window.location.href ="path/to/login";
    }else if(status==2){
    //Delete
    input.next().css('background','gray');
    }else{
    //Logged in
    input.next().css('background','orange');
    }
}});
});
});
