Struts2和Jquery整合使用异步请求

Action 中要调用的方法：   

/**
* 查询检测记录(异步请求)
* @return
*/
public void find(){
HttpServletResponse response = ServletActionContext.getResponse();
HttpServletRequest request = ServletActionContext.getRequest ();    
response.setContentType("text/xml");
response.setCharacterEncoding("GB2312");
PrintWriter writer = null;
//分页信息
PageBean page = new PageBean();
page = PageHandler.initPage();
if (index != null) {
page.setGotoPage(index);
} 
try {
request.setCharacterEncoding("iso-8859-1");
writer = response.getWriter();
view = recordService.findRecordByCondition(recordForm, page);//调用底层接口返回数据
StringBuffer buffer = ActionBean.getRecordQueryString(view, request);//进行数据封装（html）
writer.write(buffer.toString());
} catch (Exception e) {
e.printStackTrace();
}finally{
if (writer != null)
writer.close();
}

response.setHeader("Charset", "GB2312");
response.setHeader("Cache-Control", "no-store");
response.setHeader("Pragma", "no-cache");
response.setDateHeader("Expires", 0);
}

 

配置文件：
<!-- 查询历史检测记录 -->    
<action name="find" class="com.sclead.web.action.record.RecordAction" method="find"/>

页面JS函数：
//查询历史记录

function queryRecord(index){
var form = document.getElementById("find");
form.x_index.value=index;//页码
//参数
var parameter = "depId="+form.depId.value+"&devId="+form.devId.value+
"&locoType="+form.locoType.value+"&locoNO="+form.locoNO.value+
"&panType="+form.panType.value+"&isLoad="+form.isLoad.value+
"&startTime="+form.startTime.value+"&endTime="+form.endTime.value+
"&index="+index+"&flag=2";
$.ajax({
type:"GET",
url:"<%=path%>/record/find",
dataType: 'html',
cache:false,
data:parameter,
success:function(text){
//执行成功以后动态替换也页面内容，因为返回的格式为Html，直接显示即可
document.getElementById("content").innerHTML = text;    
}
});
}
