DWR【option赋值问题】

web.xml里配置

<!-- DWR配置 --> <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> <!-- /DWR配置 -->

 

DWR.xml文件

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://getahead.org/dwr/dwr20.dtd">

<dwr>

  <allow>    <create creator="spring" javascript="City">       <param name="beanName" value="biz"/>       <!--<include method="方法名" />-->    </create>     <convert converter="bean" match="com.xasxt.po.City">      <param name="include" value="id,name"/>     </convert>  </allow></dwr>

、、、、、、、、、、管用的小例子

City.findCityByShengId(shengId, {   callback:function (data) {    var shi = document.getElementByIdx_x("shi");    shi.options.length = 0;    for (var i = 0; i < data.length; i++) {     shi.options[shi.options.length] = new Option(data[i].name, data[i].id);    }   },   errorHandler:function (msg) {    alert(msg);   },   timeout:500  });
