### 我的应用(js给frameset设置rows)

1.框架frameset页面

 

 2.frametop页，如果有升级公告，将主框架页的rows调为102，否则默认为74

/*系统升级公告*/
setInterval("showUpGrade()", 1000*60*10);
function showUpGrade(){
	$.ajax({
		type:'post',
		url:'Login_showUpGrade',
		async: false ,
		dataType:'json',
		success:function(data){
	 		if(data.upGradeState=="true"){
	 			window.parent.frames['globalFrame'].rows=data.frameRows;
	 			$("#top_notice").html(data.upGradeString);
	 			$("#top_notice").css("display", "block");
	 		}
	 		else{
	 			window.parent.frames['globalFrame'].rows=data.frameRows;
	 			$("#top_notice").css("display", "none");
	 		}
	 	}
	});
}

 然后页面的

3.LoginAction中查询升级公告，并设置状态，是否有升级公告

/**
 * 显示系统升级公告
 * @author mengxianjun
 * @date 2011-11-22 下午16:09:29
 */
public void showUpGrade(){
	String upGradeString = "";
	String upGradeState = "false";//公告状态
	String frameRows = "74,*";//主frameset页的rows大小
	try {
		TUpgrade upGrade = new TUpgrade();
		upGrade.setNowDate(new Date());
		
		List upGradeList = UpGradeService.queryAll(upGrade);
		if(upGradeList.size()>0){
			upGradeString = "升级公告：";//系统升级公告字符串
			for(TUpgrade myTUpgrade: upGradeList){
				upGradeString = upGradeString+myTUpgrade.getUpgradeInfo();
			}
			upGradeState = "true";
			frameRows = "102,*";
		}
		
		PrintWriter out = this.getResponse().getWriter();
		out.print("{\"upGradeString\":\""+upGradeString+"\",\"upGradeState\":\""+
				upGradeState+"\",\"frameRows\":\""+frameRows+"\"}");
	}catch (Exception e){
		log.error("LoginAction's showUpGrade():" + e.fillInStackTrace());
	}
}

  4.sqlMap

	select
		UPGRADE_NUM as upgradeNum ,
		UPGRADE_INFO as upgradeInfo ,
		CREATE_DATE as createDate ,
		PUBLISH_DATE as publishDate ,
		FINISH_DATE as finishDate ,
		EMPLOYEE_ID as employeeId
	from (select * from t_upgrade t where t.finish_date>=sysdate order by t.create_date desc) where rownum = 1
