Give the text fields a class name and use a class selector



function validate()
   {
      var boxes = $("#details input:text.classname");
      boxes.each(function(){
          var currentVal = $(this).val();
          // do your validation here
      });
   }

$("#details input[name^='r_score']").each(function(nr){

    if($(this).val() === "") alert("Field "+(nr+1)+" is empty");

});

Use a live event handler for dynamically added content.
