我有以下代码:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<link rel="shortcut icon" href="res/favicon.ico" />
<title>My website</title>
<style type="text/css">
.wrap {
position:relative;
margin:0 auto;
width:900px;
text-align:center;
}
#header, #footer {
width:100%;
float:left;
}
#footer {
position:fixed;
bottom:0;
z-index:999999;
}
</style>
</head>
<body>
<div id="header">
<div class="wrap">
<div class="logo">
<h1>Header</h1>
</div>
<div>Menu goes here</div>
</div>
</div>
<iframe src="http://www.cnn.com"></iframe>
<div id="footer">
<div class="wrap">
<h2>Footer</h2>
</div>
</div>
</body>
</html>
如何设置iframe,以便它会占用页眉和页脚之间的所有剩余宽度和高度?

解决了它,需要一些javascript:)

var header_height = getComputedStyle(header).height;
var footer_height = getComputedStyle(footer).height;
var reserved_height = parseInt(header_height) + parseInt(footer_height);
ifrobj.style.height = eheight - reserved_height +"px";
}

</head>
<body onload="chng_iframe_height('framed','header','footer');">
<div id="header">
<div class="wrap">
<div class="logo">
<h1>Header</h1>
</div>
<div>Menu goes here</div>
</div>
</div>
<iframe src="http://www.cnn.com" id="framed"></iframe>
<div id="footer">
<div class="wrap">
<h2>Footer</h2>
</div>
</div>
</body>
</html>
基本上,我计算页眉和页脚渲染高度,得到window.innerHeight,从这些数字我知道页脚在页脚之间有多少px,所以我将该值分配给iframe和whoila它的工作原理......
另外我设置了setinterval来每隔半秒调用一次该函数,所以如果调整窗口大小,它几乎会立即更新iframe高度...

尝试在iframe中添加一个类,或者在现场设置样式:
<iframe style="height:100%; width:100%;" src="http://www.cnn.com"></iframe>
也可以尝试:
<iframe height="100%" width="100%" src="http://www.cnn.com"></iframe>
另外,不要忘记删除body标签上的填充/边距,以便页眉和页脚一直显示:
body {
margin:0;
padding: 0;
}
编辑:
如果这不起作用,则必须添加固定的宽度和高度。

我使用了.css()和$(window).height()当你使用$(window).height()时确保你有doctype为html
<script>
var resize = setInterval(function(){chng_iframe_height('framed','header','footer')},500);
function chng_iframe_height(ifrid,hid,fid) {
var eheight = $(window).height();
var ifrobj = document.getElementById(ifrid);
var header_height = $("#" + hid).css("height"); // getComputedStyle(header).height;
var footer_height = $("#" + fid).css("height");
var reserved_height = parseInt(header_height) + parseInt(footer_height);
ifrobj.style.height = eheight - reserved_height +"px";
}
</script>
