php和jsCOOKIE实现前端交互

w如何精简？

 <script>
     document.cookie = 'wjs_cookie=' + 'amz_reviews';

     function w(id) {
         document.cookie = 'wjs_cookie=' + id;
         document.getElementById(id).submit();
     }

     console.log(document.cookie);
 </script>

 <form action="" method="post" id="amz_reviews" style="display: inline;">
     <button type="submit" name="type"
             value="amz_reviews" <?php if ($_COOKIE['wjs_cookie'] == 'amz_reviews') echo 'style=" background-color:red;" '; ?>
             onclick="w('amz_reviews')">差评
     </button>
 </form>

 <form action="" method="post" id="amz_similar_sellers" style="display: inline;">
     <button type="submit"
             name="type"   <?php if ($_COOKIE['wjs_cookie'] == 'amz_similar_sellers') echo 'style=" background-color:red;" '; ?>
             value="amz_similar_sellers"
             onclick="w('amz_similar_sellers')">跟卖
     </button>
 </form>

 <form action="" method="post" id="amz_listing" style="display: inline;">
     <button type="submit"
             name="type"  <?php if ($_COOKIE['wjs_cookie'] == 'amz_listing') echo 'style=" background-color:red;" '; ?>
             value="amz_listing"
             onclick="w('amz_listing')">评分、类目变化
     </button>
 </form>
