试试这个，

<html>
<head>
 <script src="http://code.jquery.com/jquery-latest.js"></script>
 <script type="text/javascript">
   var errorExist = false;
 $(document).ready(function(){
  $("#form3").submit(function(){
     var get_count = $("#form3 input[type=text]").length;
         for(i=1; i<=get_count; i++){
          if($(".qtyy"+i).val()==""){

           errorExist  = "true";
          }
         }
     if(errorExist  == "true"){
      errorExist  = false;
      alert("Please enter value");
      return false;
     }
});
});
</script>

</head>

<body>

 <form action="" name="form3" id="form3" method="post">
    <input name="qtyy[]" type="text" class="qtyy1" size="7" />
    <input name="qtyy[]" type="text" class="qtyy2" size="7" />
    <input name="qtyy[]" type="text" class="qtyy3" size="7" />
    <input name="qtyy[]" type="text" class="qtyy4" size="7" />
    <input name="qtyy[]" type="text" class="qtyy5" size="7" />
    <input type="submit" value="Place Your Order" name="postorder" id="postorder" />
  </form>
  </body>
</html>

我觉得这是您要实现的逻辑。如果任何文本框值不为空，则表单应验证

<html>
<head>
 <script src="http://code.jquery.com/jquery-latest.js"></script>
 <script type="text/javascript">
   var errorExist = false;
 $(document).ready(function(){
  $("#form3").submit(function(){
     var get_count = $("#form3 input[type=text]").length;

     errorExist  = "true";
         for(i=1; i<=get_count; i++){
          if($(".qtyy"+i).val()!=""){

           errorExist  = "false";
          }

         }
     if(errorExist  == "true"){
      errorExist  = false;
      alert("Please enter value");
      return false;
     }
});
});
</script>

</head>

<body>

 <form action="" name="form3" id="form3" method="post">
    <input name="qtyy[]" type="text" class="qtyy1" size="7" />
    <input name="qtyy[]" type="text" class="qtyy2" size="7" />
    <input name="qtyy[]" type="text" class="qtyy3" size="7" />
    <input name="qtyy[]" type="text" class="qtyy4" size="7" />
    <input name="qtyy[]" type="text" class="qtyy5" size="7" />
    <input type="submit" value="Place Your Order" name="postorder" id="postorder" />
  </form>
  </body>
</html>

$(document).ready(function(){
    $("#form3").submit(function(){
        $("> input[type=text]",this).each(function(){
            if($(this).val()==""){
                alert("Please enter value");
                return false;
            }
        })
    })
});
