将值从jsp传递到servlet [英] passing value from jsp to servlet

问题描述

在此特定问题上，我需要您的帮助 我想将.jsp程序中的隐藏输入类型的值传递给servlet程序

I need your help in this particular issue I want to pass the value of a hidden input type in a .jsp program to a servlet program

我在做什么基本上就是这个

what I am doing is basically this

<input type="hidden" name="articleId" id="articleId" value=" <%request.getParameter("articleId");%>"/>

从servlet中获取值

and from the servlet I am getting the value

String articleId = request.getParameter("message");
        PrintWriter out = response.getWriter();
        out.println(articleId);

它没有显示任何想法. jsp的form方法是post，而servlet的方法是doPost

It doesn't print any think . the jsp form method is post and the servlet method is doPost

任何想法为什么它不传递参数?

any Ideas why it doesn't pass the parameter?

String articleId = request.getParameter("articleId");

out.println(articleId);
