Question

I have a jsp page, insert.jsp, and it has a submit button. When submit is clicked I want to display another page, confirminsert.jsp, and echo back the values that the user entered on insert.jsp. How do I implement that?

Answer 1

You don’t need JavaScript/jQuery for this. Your insert.jsp page should have a form element that contains the inputs that the user enters values in. On submit these become request parameters that confirminsert.jsp can access in server-side code and it can then echo the values back out again.

You don’t say what sort of JSP framework (if any) that you’re working with so I’ll stick to a really basic example:

In insert.jsp:

<form action="confirminsert.jsp" method="post" target="_blank">
    <label>Field One: <input name="field1" /></label>
    <label>Field Two: <input name="field2" /></label>
    <input type="Submit" value="Submit" />
</form>

In confirminsert.jsp:

Field One: <%= request.getParameter("field1") %>
Field Two: <%= request.getParameter("field2") %>

As you can see, the names passed to the request.getParameter() function are the same as the names of the input fields.
