JS操作 <frameset> <frame> 对象+js给frameset设置rows
###我的应用(js给frameset设置rows)
1.框架frameset页面
<frameset cols="*" rows="74,*" style="height: 100%;" framespacing="0" id="globalFrame">
<frame scrolling="no" marginwidth="0" marginheight="0" src="<%=request.getContextPath() %>/Login_loginTop"
name="topFrame" frameborder="0" scrolling="no" noresize="noresize" id="topFrame"/>
<frameset cols="166,8,*" id="myFrame" >
<frame frameborder="0" scrolling="no" src="<%=request.getContextPath() %>/LeftMenu_leftMenuShow"
name="leftFrame" id="leftFrame" />
<frame frameborder="0" scrolling="no" noresize="noresize" id="midFrame" name="midFrame"
src="<%=request.getContextPath() %>/Login_loginSwitch"/>
<frame frameborder="0" scrolling="auto" src="<%=request.getContextPath() %>/Login_loginRight"
name="main" id="main"/>
</frameset>
<noframes></noframes>
</frameset>
??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<body? onload="showUpGrade()">
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<TUpgrade> 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 id="queryModel" parameterClass="com.hanpeng.base.phone.model.TUpgrade" resultClass="com.hanpeng.base.phone.model.TUpgrade"> 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 </select>?

框架编程概述
一个HTML页面可以有一个或多个子框架，这些子框架以<iframe>来标记，用来显示一个独立的HTML页面。这里所讲的框架编程包括框架的自我控制以及框架之间的互相访问，例如从一个框架中引用另一个框架中的JavaScri
