實作選中複選框，并取出選中複選框的那一行資料

情況：我要批量插入表格裡的資料，使用複選框，選中複選框時，怎麼把該複選框的行的資料也取出來。

像這樣，我要取出标題，作者等資訊，咋取？在這記一下。

jsp頁面，我的表格是醬的,我要取fid，title，userid

<table class="layui-table" lay-skin="line">
                <colgroup>
                </colgroup>
                <thead>
                <tr>
                    <th><input type="checkbox" name="checkbox_all" id="checkbox_all" lay-skin="primary">全選</th>
                    <th>标題</th>
                    <th>作者</th>
                    <th>閱讀數</th>
                    <th>獲贊數</th>
                    <th>收藏數</th>
                    <th>評論數</th>
                </tr>

                </thead>
                <tbody>
                <tr>
                    <c:forEach items="${allArticles}" var="allArticles" end="10">
                    <td><input type="checkbox" name="checkbox_name" value="${allArticles.fid}" lay-skin="primary"></td>
                    <td>
                        <input hidden value="${allArticles.title}" name="title">
                        <a href="showArticle?fid=${allArticles.fid}&&userid=${allArticles.userid}" target="_blank" rel="external nofollow" >${allArticles.title}</a>
                    </td>
                    <td><input hidden value="${allArticles.userid}" name="userid">${allArticles.username}</td>
                    <td>${allArticles.readNum}</td>
                    <td>${allArticles.likes}</td>
                    <td>${allArticles.collectNum}</td>
                    <td>${allArticles.commentNum}</td>
                </tr>
                </c:forEach>
                </tbody>
            </table>

let oid = document.getElementsByName("checkbox_name");
        $('.submit_btn').on('click', function () {
                let ids = "";

                        const row = $(oid[i]).parent("td").parent("tr");//擷取選中行
                        const userid = row.find("[name='userid']").val();//擷取userid

存進數組，後面接受，那麼我要怎麼把這些資料存入資料庫？我要寫在另一篇，兩個不同的知識點，我分開寫，以後好找。
