asp.net题

现在有Frame.aspx页面和right.aspx页面

Frame.aspx页面有一个Lablel2,在Frame.aspx页面里嵌套一个Iframe 指向right.aspx，

代码：<iframe id="chatmain" src="right.aspx" frameborder="0" marginheight="0" marginwidth="0" width="134" scrolling="no" ></iframe>

现在我想要做的是在right.aspx这个页面里修改Frame.aspx页面里的Lablel2的值，通过代码或者js都行，请高手帮忙解决一下

window.parent.document.getElementById("Label2").innerHTML="新修改的值";

<iframe id="I1" frameborder="0" height="18" marginheight="0" marginwidth="0" name="I1" scrolling="no" src="welcom.aspx" width="800"></iframe>

这是我曾经做的例子，这里显示人的姓名当前日期等你看看：是在welcom里load事件写的，你的值当然可以在这里绑定了

Response.Write("<marquee direction=left height=20 scrollamount=2 scrolldelay=20 width=815 onmouseover='this.stop()' onmouseout='this.start()' >"); string year = System.DateTime.Now.Year.ToString(); string month = System.DateTime.Now.Month.ToString(); string day = System.DateTime.Now.Day.ToString(); string week = System.DateTime.Now.DayOfWeek.ToString (); string chinese = string.Empty; switch (week) { case "SunDay": chinese = "星期天"; break; case "Monday": chinese = "星期一"; break; case "Tuesday": chinese = "星期二"; break; case "Wednesday": chinese= "星期三"; break; case "Thursday": chinese = "星期四"; break; case "Friday": chinese = "星期五"; break; case "Saturday": chinese = "星期六"; break; } Response.Write("<div style ='font-size :14px; font-family :华文仿宋;color:#FF3333'>当前用户是：" + UserName + "，" + " 今天是" + year + "年" + month + "月" + day + "日，" + chinese + "</div>"); Response.Write("</marquee>");

希望对你有帮助吧
