DWR填充下拉框

公司项目中有用到DWR这种方式，初次学习不免遇到一些问题。
一、先从简单的Hello World说起，参考[url]http://blog.csdn.net/caterpillar_here/archive/2006/09/06/1186566.aspx [/url]
web.xml代码如下

    <servlet>
     <servlet-name>dwr-invoker</servlet-name>
        <servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
        <init-param>
            <param-name>debug</param-name>
            <param-value>true</param-value>
        </init-param>
        <load-on-startup>2</load-on-startup>
    </servlet>
        <servlet-mapping>
        <servlet-name>dwr-invoker</servlet-name>
        <url-pattern>/dwr/*</url-pattern>
    </servlet-mapping>

JAVA代码如下：

package com.zqw.dwr.test;
public class Hello {
	  public String hello(String name) {
	      return "哈楼！" + name + "！World 世界与DWR实验！";
	    }
}

dwr.xml代码如下：

<?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="new" javascript="Hello">
      <param name="class" value="com.zqw.dwr.test.Hello" />
    </create>
  </allow>
</dwr>

index.jsp部分代码如下：

<script type='text/javascript' src='<%=request.getContextPath()%>/dwr/interface/Hello.js'></script>
<script type='text/javascript' src='<%=request.getContextPath()%>/dwr/engine.js'></script>
<script type='text/javascript' src='<%=request.getContextPath()%>/dwr/util.js'></script>不要漏了引用。
<input id="user" type="text" />
<input type='button' value='哈楼' onclick="hello()" /> 
<div id="result"></div>

hello world的简单Demo也就完成了。


二、填充下拉框
XinxiServiceImpl的代码如下：

	public List findDWRallxinxi() {
		List ls= xinxiDao.findAllXinxi();//把所有的信息查询出来
		List rtnList = new ArrayList();
		Map optMapKong = new HashMap();
		optMapKong.put("xinxisex", "-----请选择-----");
		optMapKong.put("xinxisal", "");
		optMapKong.put("xinxiid", "");
		rtnList.add(optMapKong);
		for (int i = 0; ls != null && i < ls.size(); i++) {
			Xinxi jf = (Xinxi) ls.get(i);
			Map optMap = new HashMap();
			optMap.put("xinxisex", jf.getSex());
			optMap.put("xinxisal", jf.getSal());
			optMap.put("xinxiid", jf.getId());
			rtnList.add(optMap);
		}
		return rtnList;
	}

dwr.xml代码如下：

         <create creator="spring" javascript="xinxiDWRallxinxi">
             <param name="beanName" value="xinxiDWRallxinxi"/>
             <include method="findDWRallxinxi"/>          
         </create>

当然在Spring配置文件applicationContext.xml下增加bean

    <bean id="xinxiDWRallxinxi" class="com.zqw.service.impl.XinxiServiceImpl">  
    </bean>  

index.jsp代码如下：

var $j = jQuery.noConflict();
$j(document).ready(function() {
    getXinxiSelect();
});
function getXinxiSelect(){
	xinxiDWRallxinxi.findDWRallxinxi(CallbackXinxi);
}
function CallbackXinxi(returnValue){
	var xinxiSelectList = '<s:property value="Xinxivalue"/>';
	DWRUtil.removeAllOptions("xinxiSelectList");
	DWRUtil.addOptions("xinxiSelectList", returnValue, "xinxisex", "xinxisal");
	DWRUtil.setValue("xinxiSelectList",xinxiSelectList);
}


<script type='text/javascript' src='<%=request.getContextPath()%>/dwr/engine.js'></script>
<script type='text/javascript' src='<%=request.getContextPath()%>/dwr/util.js'></script>
<script type="text/javascript" src="<%=request.getContextPath()%>/dwr/interface/xinxiDWRallxinxi.js"></script><!--不要漏了添加-->


 <select name="xinxi.sal"  id="xinxiSelectList"  > 

这样便把所有的sal全部加载到下拉框中
