Question

我正在国家公园的Node JS中创建一个项目，从数据库中获取公园列表并将其显示在我的主页上。现在，在显示的各种公园列表中，我必须单击View Page按钮将那个公园的名称的值传递到应用程序的下一页。我该如何在Node JS中做到这一点

这是我的home.ejs文件

点击以下按钮代码

<div class="card-body">
                  <h5 class="card-title"><%=nationalParks[k].nationalPark %></h5>
                  <a href="/NationalPark" class="btn btn-primary btn-sm" id="viewNationalPark">View Page</a>
                </div>

我需要将<%=nationalParks[k].nationalPark %>的值传递到应用程序的下一页，是否可以在Node JS中做到这一点。提前致谢。

在Node JS中的按钮单击上的EJS之间传递变量
