This will works for you.

$('#submit').on(click, function () { 


        $('#lang2').find("input[type=text],textarea").each(function (e)
        {

                if ($(this).val().trim() === "")
                {
                   Alert('Please Enter Value')
                   return false;    
                 }
                }

        });
