最�q�无聊，做了一�?span class="hilite1">DWR的验证和eXtremeTable的应用的例子

前期的系�l�创建、struts、hibernate、spring的集成工作就不用说了�Q�一路下�?#8230;………

主要�?span class="hilite1">DWR的应用，它用于表单验证：

1、先看它的配�|�：

�Q?�Q�在web.xml里加上：

xml 代码

<servlet>
<servlet-name>dwr-invokerservlet-name>
<servlet-class>uk.ltd.getahead.dwr.DWRServletservlet-class>
<init-param>
<param-name>debugparam-name>
<param-value>trueparam-value>
init-param>
<load-on-startup>1load-on-startup>
servlet>
<servlet-mapping>
<servlet-name>dwr-invokerservlet-name>
<url-pattern>/dwr/*url-pattern>
servlet-mapping>

�Q?�Q�再��Z��个类�Q�用于获取验证输��Z��息的属性文�Ӟ��q�个文�g是参考了良葛�?�?strong>DWR 入門與應用（一�Q?/font>

里的Book代码

java 代码

package test.common;
import java.util.ResourceBundle;
public class GetProperties{
private ResourceBundle resource;
public GetProperties()
{
resource = ResourceBundle.getBundle("dwrPro");
}
public String getDescription(String key)
{
return resource.getString(key);
}
}

�Q?�Q�编写属性文�?span class="hilite1">dwrPro_zh_CN.propertie�Q�中文）�?span class="hilite1">dwr_en.properties�Q�英文）

java 代码

username_hasUsed = 用户名已用，请选择别的用户�?
username_canUse = 恭喜�Q�用户名可以使用
username_hasUsed =username has used!
username_canUse = username can use!

�Q?�Q�配�|?span

spring beanName

�q�里应该大家都懂�Q�就不罗嗦了 class="hilite1">dwr.xml�Q�里面用了spring的bean 和java�c?/p> class="code_title">xml 代码 class="dp-highlighter"> class="bar"> class="alt"><dwr> class=""> class="alt"> <allow> class=""> <create creator="spring" javascript="userManager"> class="alt"> <param name="beanName" value="userManager"/> class=""> <include method="findUserIsExist"/> class="alt"> create> class=""> class="alt"> <create creator="new" javascript="User" scope="application"> class=""> <param name="class" value="test.common.GetProperties"/> class="alt"> create> class=""> allow> class="alt">dwr> 的value =“userManager”从applicationContext.xml里取�?/p> class="code_title">xml 代码 class="dp-highlighter"> class="bar"> class="alt"><bean id="userManagerTarget" class="test.spring.serviceImpl.UserServiceImpl"> class=""><property name="userDao"> class="alt"> <ref bean="userDao"/> class="">property> class="alt">bean> class=""> class="alt"> class=""> <bean id="userManager" class="org.springframework.aop.framework.ProxyFactoryBean"> class="alt"> <property name="proxyInterfaces"> class=""> <value>test.spring.service.IUserServicevalue> class="alt"> property> class=""> <property name="interceptorNames"> class="alt"> <list> class=""> <idref bean="transactionInterceptor"/> class="alt"> <idref bean="userManagerTarget"/> class=""> list> class="alt"> property> class=""> bean>

�Q?�Q�配好了�q�些�Q�就可以在页面里用了

java 代码

"-//W3C//DTD HTML 4.01 Transitional//EN">
interface/userManager.js'>
interface/GetProperties.js'>
}
"0">
Login:
"text" name="user.name" id="username" onblur="checkName()"/>"check_username">
Password:
"password" name="user.password" id="username" onblur="checkpassword()"/>"check_password">
"2" align="center">

�q�里当填了Login框，当光标从输入框移开时就实行�?/p>

js 代码

function checkName()
{
var username = document.userForm.username.value;
userManager.findUserIsExist(username,callback);
}

userManager.findUserIsExist(username,callback)时关键，�q�里��q��?/font>

��d��dwr.xml�?font face="Arial">userManager�Q�然后读取applicationContext.xml�?font face="Arial">userManager bean �Q�进而实�?font face="Arial">findUserIsExist�Ҏ(gu��)��?/font>
