javascript - 从定义的 获取值 (ASP.NET MVC)

Question

我有 View ，可以通过表格显示一些数据

这是代码

 @foreach (var item in Model)
    {
        <tr >
            <td class="point">
                @(rowNo += 1)
            </td>
            <td style="text-align: center; font-size: 18px;">
                @Html.DisplayFor(modelItem => item.Email)
                @Html.Hidden("clientEmail", item.Email)
            </td>
            <td style="text-align: center; font-size: 18px;">
                @Html.DisplayFor(modelItem => item.UserName)
            </td>
            <td style="text-align: center; font-size: 18px;">
                @Html.DisplayFor(modelItem => item.Position)
            </td>
            <td style="text-align: center; font-size: 18px;">
                @Html.DisplayFor(modelItem => item.Company.CompanyName)
            </td>
            <td style="text-align: end;">


                <button type="submit" id="send" class="sendinviteclass" style="color: white">Отправить приглашение</button>

我有带有 id="send" 的按钮，我需要通过 JS 通过它获取电子邮件。

我的麻烦在于 - 例如，我可以在表中包含 5 行，因此我可以有 5 个按钮。

我如何通过 JS 从电子邮件中获取我需要的值(value)？

UPDATE

这是页面源代码

 <div style="padding-left: 70px; padding-bottom: 20px;">
            <p>
                <a href="/">

Answer 1

将 data- prop 添加到您的按钮，例如:

<button type="submit" id="send" onclick="sender(this)" data-email="@item.email" class="sendinviteclass" style="color: white">Отправить приглашение</button>

在 JS 中:

var email = $(this).data('email')

假设this是您的按钮。
