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>
