frame 之间访问

index.asp代码

?

<frameset rows="50,*,20" cols="*" frameborder="no" border="0" framespacing="0">

    <frame src="Top.aspx" id="iframeTop" scrolling="no" noresize>

    <frameset id="fs" rows="*" cols="150,9,*" frameborder="no" border="0" framespacing="0">

        <frame src="Left.aspx" id="iframeLeft" scrolling="auto" frameborder="NO" border="0" framespacing="0">

        <frame src="Split.aspx" scrolling="auto" frameborder="NO" border="0" framespacing="0">

        <frame name="Right" id="Right" src=<%=strRightURL %> scrolling="auto" frameborder="NO" border="0" framespacing="0">

    </frameset>

    <frame name="Bottom" id="Bottom" src="Bottom.aspx" scrolling="NO" noresize>

</frameset>

 frame Right 中某个页面要访问其他frame的控件：

?

var oDoc = top.parent.document;

         var oFrameLeft = oDoc.frames["iframeLeft"];

         oFrameLeft.document.getElementById("mdiv").style.height = oFrameLeft.document.body.offsetHeight;

         oFrameLeft.document.getElementById("mdiv").style.width  = oFrameLeft.document.body.offsetWidth;

         var oFrameTop = oDoc.frames["iframeTop"];

         oFrameTop.document.getElementById("mdiv").style.height = oFrameTop.document.body.offsetHeight;

         oFrameTop.document.getElementById("mdiv").style.width  = oFrameTop.document.body.offsetWidth;

 mdiv为Left中的一个div，如果要访问到，必须要有body，且在body里面。不然document.getElementById("mdiv").style报错。
