java - 如何将用户输入从 HTML 文件传递​​到 Java servlet？

Question

我有 1 个 html 文件被调用page2.html，我正在使用 twitter 引导工具包。我正在开发一个开发考试自动座位安排的项目，我正在尝试开发一个界面，允许管理员“选择”学生可以坐的位置。

我正在使用 JavaScript 更改占用座位的颜色。现在的问题是，如何将 Occupied Seat 的值发送到 Servlet？由于我在这里只更改颜色，因此它不是典型的输入值。正如代码所解释的，我只使用<div>标签来绘制点击时的“座位”，它会被“占用”。

示例图片：我会发布一个示例图片，但它不会让我没有 10 声望。

代码如下：

<div class="alert alert-success hide" id="alert1">
                        <h4>Select the seating arrangement for <i>Floor 1</i>.</h4>
                    </div>
                    <form class="hide" id="seat-select1" method="get" action="Seat1">
                        <div class="btn" style="position:absolute; top:300px; left:210px" onclick="col(0,1)" >Toggle</div>
