Try using

$.ajax({
    url: 'http://localhost/s/login_request',
    type:'POST',
    data:{uname:uname,pass:pass},
    dataType:"json",
    cache: false,
    success: function(data) { },
    fail: function(xhr, status) { alert(JSON.stringify(xhr)) },
    error: function() { },
    complete: function() { alert('1234') }
});
