java - jsp 内的 cfm : how to get a variable from the jsp to the cfm?

Question

我正在尝试将一个变量从一个 jsp 页面传递到该 jsp 内导入的 cfm。

以下是字符串的存储方式 ( http://www.tenaquip.com/shop/optin-form-test.jsp?lang=en ):

<%  
    String email_address = "test@test.com"; 
%>

它需要传递给 c:import cfm:

<c:import url="https://www.tenaquip.com/cfusion/forms/joinmailing_eng-test.cfm"/>

Answer 1

解决方案分为两步:

1- 将变量传递出 scriptlet <% ... %>到原始 jsp 页面的其余部分:

<%
  String email_address = "test@test.com";
  pageContext.setAttribute("email_address_to_send", email_address); 
%>

2- 将变量转发到下一页:

<c:import url="https://www.tenaquip.com/cfusion/forms/joinmailing_eng-test.cfm">
     <c:param name="email_received">${email_address_to_send}</c:param>
</c:import>

然后你可以使用变量 #email_received#在你的表格中
