javascript - 如何使用 jQUery 中的数据属性更新表中的数据

Question

我在 html 中有这个表，我需要使用数据用户 ID 更新用户，我对此进行了操作，但此函数没有更改网页中的任何内容。

这里，我有 data-userid 的 html 表代码:

 <table id="tblList">
        <tbody id="someTest">
          <tr data-userid="801992084067"></tr>
          <tr data-userid="451207954179"></tr>
          <tr data-userid="310896831399"></tr>
          <tr data-userid="863939754980"></tr>
          <tr data-userid="1123542226482"></tr>
        </tbody>
      </table>

这里我有更新功能。

function updateUser(userId, user) {

    var foundUser = findUser(userId);


    foundUser.username = user.username;
    foundUser.level = user.level;
    foundUser.registrationStatus = user.registrationStatus;
    foundUser.registrationDate = user.registrationDate;


    for(var i = 1; i<userId.length; i++){
        $("#someTest tr[data-userid = 'userid " + userId[i] + "']").each(function () {
            // if (rowId === userId) {

                var table = $('#tblList');

                var row = "<tr data-userid=" + foundUser.id + ">"
                    + " <td>"
                    + "     <img src='resources/img/edit.png' alt='Edit' class='btnEdit'/>"
                    + "     <img src='resources/img/delete.png' alt='deleteUser' class='btnDelete'/>"
                    + "</td>"
                    + " <td>" + foundUser.username + "</td>"
                    + " <td>" + foundUser.level + "</td>"
                    + " <td>" + foundUser.registrationStatus + "</td>"
                    + " <td>" + foundUser.registrationDate + "</td>"
                    + "</tr>";
                table.append(row);
            // }
        });
    }
    hidePopup();
}

我的问题如下:在 updateUser 函数中该怎么做，因为当我更改用户时，要在浏览器中查看该更改？

试试这个

function updateUser(userId, user) {

        var foundUser = findUser(userId);


        foundUser.username = user.username;
        foundUser.level = user.level;
        foundUser.registrationStatus = user.registrationStatus;
        foundUser.registrationDate = user.registrationDate;

        var row = " <td>"
                        + "     <img src='resources/img/edit.png' alt='Edit' class='btnEdit'/>"
                        + "     <img src='resources/img/delete.png' alt='deleteUser' class='btnDelete'/>"
                        + "</td>"
                        + " <td>" + foundUser.username + "</td>"
                        + " <td>" + foundUser.level + "</td>"
                        + " <td>" + foundUser.registrationStatus + "</td>"
                        + " <td>" + foundUser.registrationDate + "</td>";


        $("#someTest tr[data-userid = '" + userId + "']").html(row)
        hidePopup();
    }
