我浏览了类似的帖子,但没有找到与我的场景真正相关的任何内容。
我有一个摘要页面,其中有iframe
几个页面,用户在前往摘要页面的途中已经浏览了这些页面。在每个被 iframe 的页面中。我.toggle
用来展开/折叠页面的内容。
我发现的问题是我在第一次加载摘要页面时使用了一个脚本来调整iframe
它所包含的页面内容的大小,但是当我单击以切换该内容并折叠它时,它保持iframe
相同的大小,因此有一大块空白。
我猜我需要将内容从包含的页面发送回摘要页面,说明内容大小已更改,因此重新调整大小,iframe
但不确定如何执行此操作。
有人可以指出我正确的方向吗?
文件的一个例子是...
父.html
<link rel="stylesheet" type="text/css" href="styles.css" />
<script type="text/javascript">
// Resize an iframe so it's as tall as its contents. This could be much shorter but is expanded for clarity.
function size_frame(frame_name, frame_id)
{
// Get the iframe element
var frame_element = document.getElementById(frame_id);
// Get the iframe frame-window object. Note this has different properties to frame_element.
var frame_window = frames[frame_name];
// Set the height to 1px first, because some browsers will give you the maximum height of either the
// frame or its contents, when you try to read the scrollHeight property as we do below.
frame_element.style.height = "1px";
// set the height of the iframe element to the "scrollHeight" of the document element of the frame window.
frame_element.style.height = frame_window.document.documentElement.scrollHeight +"px";
}
</script>
