一起来看代码：
2.servlet
路径:wapTest
| 1.wapTest.jsp <%@ page language="java" import="java.util.*" contentType="text/vnd.wap.wml;charset=GBK"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <?xml version="1.0" Encoding="GBK"?> <!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" <wml> <head> <meta http-equiv="contentType" content="text/vnd.wap.wml"/> <meta http-equiv="Expires" content=" 0"/> <meta http-equiv="Cache-Control" content="no-cache"/> </head> <card id="list" title="choose company"> <select name="company"> <option onpick="#sa">索爱</option> <option onpick="#nokia">Nokia</option> </select> </card> <card id="sa" title="索爱"> <do type="accept" label="OK"> <go href="#test"></go> </do> <select name="type"> <option value="索爱1">索爱1</option> <option value="索爱2">索爱2</option> </select> </card> <card id="nokia" title="Nokia"> <do type="accept" label="OK"> <go href="#test"></go> </do> <select name="type"> <option value="Nokia1">Nokia1</option> <option value="Nokia2">Nokia2</option> </select> </card> <card id="test" title="postfield"> <p>型号:$type</p> <do type="accept" label="submit"> <go href="wapTest" method="post"> <postfield name="company" value="$type"/> </go> </do> </card></wml> |
路径:wapTest
| public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/vnd.wap.wml;charset=gbk"); PrintWriter out = response.getWriter(); out.print("<wml>"); if(request.getParameter("company")!=null) { out.print("<card><p>company is:"+request.getParameter("company")); out.print("</p></card>"); } out.print("</wml>"); out.flush(); out.close(); } |
当然,jsp就可以通过url传递<a href="test.jsp?param=text">jsp</a>
