2、action中对级联查询的操作

//保存回复处理结果
	public String deal(){
		if(complain != null){
			Complain tem = complainService.findObjectById(complain.getCompId());
			//1、更新投诉的状态为已受理
			if(!Complain.COMPLAIN_STATE_DONE.equals(tem.getState())){ //更新状态为已受理
				tem.setState(Complain.COMPLAIN_STATE_DONE);
			}
			//2、保存回复信息
			if(reply != null){
				reply.setComplain(tem);
				reply.setReplyTime(new Timestamp(new Date().getTime()));
				tem.getComplainReplies().add(reply);
			}
			complainService.update(tem);
		}
		return "list";
	}

3、jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<html>
<head>
<%@include file="/common/header.jsp"%>
<title>用户管理</title>
<!--   引入日历插件-->
<script type="text/javascript" src="${basePath}js/datepicker/WdatePicker.js"></script>
<script type="text/javascript">
	var vResult = false;
	function doVerify() {
		//1.获取账号
		var account = $("#account").val();
		if (account != "") {
			//2.效验
			$.ajax({
				url : "${basePath}nsfw/user_verifyAccount.action",
				data : {
					"user.account" : account
				},
				type : "post",
				async : false,//非异步，主要为了下边的提交
				success : function(msg) {
					if ("true" != msg) {
						//账号已经存在
						alert("账号已经存在，请使用其他账号！");
						//定焦
						$("#account").focus();
						vResult = false;
					} else {
						vResult = true;
					}
				}
			});
		}
	}
	//2.提交表单
	function doSubmit() {
		var name = $("#name");
		if (name.val() == "") {
			alert("用户名不能为空");
			name.focus();
			return false;
		}
		var password = $("#password");
		if (password.val() == "") {
			alert("密码不能为空");
			password.focus();
			return false;
		}
		//账号验证
		doVerify();
		//表单提交
		if (vResult) {
			document.forms[0].submit();
		}
	}
</script>
