JSP小问题,本页JSP处理form表单出错求助
一个JSP页面里有个form表单,其响应可以用本jsp来响应吧,当然里面有相应的Scriptlet
如下代码:
<%@ page language= "java " import= "java.util.* "%>
<%@ page contentType= "text/html; charset=GBK "%>
<%!ArrayList list = null;%>
<%!public ArrayList addUser(String userName, String userIdcard) {
ArrayList ls = new ArrayList();
ls.add(userName);
ls.add(userIdcard);
return ls;
}%>
<%!public String tdUserName() {
String u = " ";
for (int i = 0; i < list.size(); i++) {
if (i % 2 == 0) {
u = list.get(i).toString();
}
}
return u;
}%>
<%!public String tdUserIdCard() {
String uc = " ";
for (int i = 0; i < list.size(); i++) {
if (i % 2 == 1) {
uc = list.get(i).toString();
}
}
return uc;
}%>
<%!public String tdUserBd() {
String idCard = tdUserIdCard();
String bd = idCard.substring(6, 10) + "- " + idCard.substring(10, 12)
+ "- " + idCard.substring(12, 14);
return bd;
}%>
