(新)Jquery ajax请求Struts2 action 返回xml数据

1.js代码

 

//案件来源
function loadCaseSources(position_id){
	var  action="/caseSource/getAllCaseSource.action";
	var  data="";
	var  error_message="加载案件来源数据失败！";
	getCaseSourcesSelect(action,data,position_id,error_message);
}

function getCaseSourcesSelect(action,data,position_id,error_message)
{
	$.ajax({
	  url:action, 
	  data:data,
      type: 'POST', 
      dataType: 'xml',                            
      error: function(){     
       alert(error_message); 
      }, 
      success:function(circumstancesXML)
      {
      	 $(circumstancesXML).find("option").each(function(){
			   var dm=$(this).children("option_value").text();  
			   var mc=$(this).children("option_name").text();
			   $("#"+position_id).append("<option value="+dm+">"+mc+"</option>");
		  });
		  $("#"+position_id).css("text-align","center");
      }
	});
}

 

 struts配置

	<!--案件来源-->
	<package name="caseSource" extends="default" namespace="/caseSource">			
		<action name="getAllCaseSource" class="gov.tax.wfwz.business.action.commons.CaseSourceAction" method="getAllCaseSource">
			<result name="xml">/module/common/caseSource.jsp</result>
		</action>
	</package>

 

 

2.Action 代码

 

/**
 * 案件来源
 * @author lixueli
 * @date 2010-11-24
 */
public class CaseSourceAction extends BaseAction {

	private CaseSourceService caseSourceService;

	public void setCaseSourceService(CaseSourceService caseSourceService) {
		this.caseSourceService = caseSourceService;
	}

	public String getAllCaseSource() throws BusinessException, Exception {
		try {
			List<CaseSource> caseSources = caseSourceService.getAllCaseSource();
			request.setAttribute("caseSources", caseSources);
			return "xml";
		} catch (Exception e) {
			ErrorReData.excecute(request, e);
			throw e;
		}
	}

}

	<circumstances>
	<c:forEach items="${caseSources}" var="caseSource">
		<option>
			<option_name><c:out value="${caseSource.wfajly_mc}"/></option_name>

这个配置稍显繁琐,需要在jsp中固定xml结构
可用xml转换的库,比如xtream,等等,在action里用stream result 直接输出,免去一个jsp的工作!!!
