在http://127.0.0.1:8080/poject/dwr 里测试成功，可以调用到那个方法，并且是想要的结果!!
但在jsp页面种，调用dwr类里的方法无法进入改方法 没任何异常和提示
以下是dwr配置文件
[code="java"]
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN" "http://www.getahead.ltd.uk/dwr/dwr10.dtd">
[/code]
以下是web.xml配置问下
[code="java"]
<!-- Spring监听 -->
contextConfigLocation
/WEB-INF/classes/applicationContext.xml
org.springframework.web.context.ContextLoaderListener
<!-- dwr -->
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>
org.directwebremoting.servlet.DwrServlet
</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>dwr-invoker</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
[/code]
以下是 applicationContext.xml
[code="java"]
<!-- dwr配置 -->
[/code]
一下是dwr类
[code="java"]
public boolean valeng(String names){
System.out.println("-----");
Query query = getSession().createQuery("FROM Account WHERE account=? ");
query.setString(0,names);
List list = query.list();
for(int i=0;i<list.size();i++){
dao.Account account = (Account)list.get(i);
if(account.getAccount().equals(names)){
return false;
}
}
return true;
}
[/code]
jsp页面文件

function regUserChked()
{
var username =$[color=red]{"account"}.[/color]value; //这里写错啦，应该是var username =[color=red]$("account").value; [/color]
Test.valeng(username,showData);
}
你是用jquery框架吗
那就是var username =document.getElementById("account").value;
你是用jquery框架就变这样
var username = $("#account").val();
