Javascript 将EJS变量传递给app.post节点js

我有一个ejs文件，变量如下：

<form action="/profile" method="post">
<p>
    <% var ten = user.username %>
    <strong>id</strong>: <%= user.id %><br>
    <strong>username</strong>: <%= ten %><br>
    <strong>password</strong>: <%= user.password %>
</p>
<p id="passwd" name="passwd" ><%= user.username %></p>
<button type="submit" class="btn btn-warning btn-lg">Wallet</button>
</form>

但它不起作用。我甚至尝试使用：

let password = req.body.passwd;  
let password = req.body[passwd];

---

但还是不行

您需要使用表单元素，如input、select、textarea等。如果不想使其可见，请使用隐藏类型，如下所示

<form action="/profile" method="post">
    <p>
        <% var ten = user.username %>
        <strong>id</strong>: <%= user.id %><br>
        <strong>username</strong>: <%= ten %><br>
        <strong>password</strong>: <%= user.password %>
    </p>
    <p id="passwd" name="passwd" ><%= user.username %></p>
    <!-- these fields will be sent to server -->
    <input type="hidden" name="username" value="<%= user.username %>">
    <input type="hidden" name="password" value="<%= user.password %>">

    <button type="submit" class="btn btn-warning btn-lg">Wallet</button>
</form>

id：

用户名：

<form action="/profile" method="post">
    <p>
        <% var ten = user.username %>
        <strong>id</strong>: <%= user.id %><br>
        <strong>username</strong>: <%= ten %><br>
        <strong>password</strong>: <%= user.password %>
    </p>
    <p id="passwd" name="passwd" ><%= user.username %></p>
    <!-- these fields will be sent to server -->
    <input type="hidden" name="username" value="<%= user.username %>">
    <input type="hidden" name="password" value="<%= user.password %>">

    <button type="submit" class="btn btn-warning btn-lg">Wallet</button>
</form>
