Struts2和Jquery整合使用异步请求

来源：互联网发布：mac air香港价格编辑：程序博客网时间：2024/06/06 19:48

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：

<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;    }});}
