here's what i did i have created a jsp page cardholder
<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE HTML>
<%
String client = (String) request.getAttribute("clientId");
%>
<html>
<head>
<style type="text/css">

</style>
<script type="text/javascript">
function clear()

}
function changeStyle() {
var v1 ="<%=client%>";
if (!(v1 == "null")) {
document.getElementsByName('clientNo')[0].value = v1;
alert("client " + v1 + " registered successfully");
}
}
</script>
</head>
<body onload="changeStyle();">
<h3>Card Holder Details</h3>
<s:actionerror/>
<s:form action="registerClient">

</tr>
</s:div>
</s:form>

</html>
这是我的xml验证文件
here is my xml validation file
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://struts.apache.org/dtds/xwork-validator-1.0.2.dtd">

</field>
<field name="firstName">

</field-validator>
</field>
<field name="lastName">

</validators>
当我运行此页面时，我在字段上收到错误消息，但我想在每个字段旁边显示它们. 请帮忙.
when i run this page i am getting error messages over the fields but i want to display them beside each field. please help.
这是我的动作课
package com.struts.lifewardscard;
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.ArrayList;
import java.util.Map;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.ServletActionContext;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.SessionAware;
import oracle.jdbc.driver.OracleTypes;
import com.struts.lifewardscard.CardHolderForm;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
public class CardHolderRegistration extends ActionSupport implements ModelDriven{
CardHolderForm cardform=new CardHolderForm();
public String execute() throws Exception{
String clientId=null;
HttpServletRequest request = ServletActionContext.getRequest();
clientId=saveCardHolderDetails();
request.setAttribute("clientId", clientId);
return "success";
}
@Override
public Object getModel() {
// TODO Auto-generated method stub
return cardform;
}
这是验证后生成的示例代码
this is sample code generated after validation
<tr errorFor="registerClient_custIdNum">
<td align="center" valign="top" colspan="2"><span class="errorMessage">Customer ID is required.</span></td>
</tr>
<tr>
<td class="tdLabel"><label for="registerClient_custIdNum" class="errorLabel">CUSTOMER ID NUMBER:</label></td>
<td
><input type="text" name="custIdNum" value="" id="registerClient_custIdNum"/></td>
</tr>
我希望错误显示消息与输入行在同一行 不在新行中.
i want the error display message to be on the same row as input row not in a new row.
推荐答案
您是说我可以仅使用CSS就能做到这一点，请给我一个例子.
you are saying i can be able to do it with CSS alone can you please give me an example.
几乎所有的事情都可以通过CSS来完成.但是，在这种情况下，它不干净并且有缺点(主要是由于colspan造成的)，因此有两个更好的选择:
Almost everything can be done with CSS alone. In this case, however, it's not clean and has drawbacks (mainly due to the colspan), so two better alternatives are:
-
使用简单的主题并自己编写标记，如下所示:
use the simple theme and write the mark-up by yourself, like this:
<s:textfield id="foo" key="foo" />
<s:fielderror fieldName="foo" />
创建自定义主题，分叉XHTML并仅更改要更改的内容，例如fieldError位置.
create a custom theme, forking the XHTML one and changing only the things you want to differ, like fieldError placement.
但是，由于您提出了要求，并且作为一种纯学术练习(不要在家中尝试)，所以它是:
However, since you asked, and as a pure academic exercise (don't try this at home), here it is:
table {
margin: 10px;
border: 1px solid silver;
}
tr {
background: #eee;
}
tr[errorFor] {
color: red;
}
tr[errorFor]+tr {
color: forestGreen;
}
#example1 tr[errorFor] {
display: inline-block;
}
#example1 tr[errorFor]+tr {
display: inline-block;
}
#example2 tr[errorFor] {
float: right;
}
#example2 tr[errorFor]+tr {
float: right;
}
<table>
<tr errorFor="registerClient_custIdNum">
<td align="center" valign="top" colspan="2"><span class="errorMessage">Standard error label</span>
</td>
</tr>
<tr>
<td class="tdLabel">
<label class="errorLabel">Label</label>
</td>
<td>
<input type="text" />
</td>
</tr>
<tr>
<td class="tdLabel">
<label>foo</label>
</td>
<td>
bar
</td>
</tr>
</table>
<table id="example1">
<tr errorFor="registerClient_custIdNum">
<td align="center" valign="top" colspan="2"><span class="errorMessage">Inline-block error label </span>
</td>
</tr>
<tr>
<td class="tdLabel">
<label class="errorLabel">Label</label>
</td>
<td>
<input type="text" />
</td>
</tr>
<tr>
<td class="tdLabel">
<label>foo</label>
</td>
<td>
bar
</td>
</tr>
</table>
<table id="example2">
<tr errorFor="registerClient_custIdNum">
<td align="center" valign="top" colspan="2"><span class="errorMessage">Floating error label</span>
</td>
</tr>
<tr>
<td class="tdLabel">
<label class="errorLabel">Label</label>
</td>
<td>
<input type="text" />
</td>
</tr>
<tr>
<td class="tdLabel">
<label>foo</label>
</td>
<td>
bar
</td>
</tr>
</table>
