在另一个JSP页面上打印JSP表单数据

Question

I have a jsp form that takes different inputs from user. How can I print the submitted data on another jsp page?

Answer 1

In your first JSP page:

<form method="post" action="otherPage.jsp">
   <input type="text" name="firstName">
   <input type="submit" value="Submit">
</form>

then on the otherPage.jsp you can get the value of the input:

<%
    String name = request.getParameter("firstName");
    out.println("Firstname: " + name);
%>

..although using scriptlets is normally discouraged.

If you want to use eg Spring MVC you post the form to a Controller which handles the request and there you can pass the parameters forward.

Answer 2

The use of scriptlets in JSP is strongly discouraged:

You can achieve the same using JSP Expression Language (JSP EL):

<p>First name was ${param.firstName}</p>
