在JSP的当前页面上显示表单处理结果 [英] Display form-processing results on current page in JSP

问题描述

目前，我能够将一些表单数据从HTML页面发送到Servlet，进行处理，然后通过转发/重定向到displayresults.jsp页面来返回结果；但是我想知道是否有一种方法可以以这种方式处理表单提交，然后将结果返回到初始页面?这样我想返回的内容就会显示在表格下方.

Currently I'm able to send some form data from an HTML page to a Servlet, process it, and return the result by forwarding/redirecting to a displayresults.jsp page; However I'm wondering if there's a way to process a form submission in this fashion and then return the results to the initial page? So that whatever I wish to return shows up below the form.

最后的想法是将搜索功能放在顶部，然后将搜索结果显示在同一页面的下方.

The idea in the end will be to have a search function up top, then have the search results appear below on the same page.

推荐答案

是

1. 将结果从servlet中粘贴到请求对象中
2. 让servlet 转发回到请求页面
3. 在JSP中添加一些代码，以从请求对象中提取结果并显示出来

1. Stick the results into the request object from within the servlet
2. Get the servlet to forward back to the request page
3. Add some code into the JSP to pull out the results from the request object and display them

如果您的用例意味着您将从其他地方的搜索结果中跳出来，然后返回，则您可能希望在会话中保留搜索结果.

If your usecase means that you'll be jumping from the search results elsewhere and back you may wish to maintain the search results in the session.
