//动态设置窗体的高度和宽度

function SetWinHeight(obj)

{

var win=obj;

if (document.getElementById)

{

if (win && !window.opera)

{

if (win.contentDocument && win.contentDocument.body.offsetHeight)

win.height = win.contentDocument.body.offsetHeight;

else if(win.Document && win.Document.body.scrollHeight)

win.height = win.Document.body.scrollHeight;

if (win.contentDocument && win.contentDocument.body.offsetWidth)

win.width = win.contentDocument.body.offsetWidth;

else if(win.Document && win.Document.body.scrollWidth)

win.width = win.Document.body.scrollWidth;

}

}

}

parent.document.all("框架ID名").style.height=document.body.scrollHeight;

parent.document.all("框架ID名").style.width=document.body.scrollWidth;
