I'm trying to resize (make bigger or smaller) an iframe based on it's contents. After a click on each page a method is called which does the resizing.
我正在尝试根据它的内容调整大小(变大或变小)iframe。单击每个页面后,将调用一个调整大小的方法。
In Chrome I can make the iframe bigger, but not smaller. document.body.scrollHeight is always the biggest value.
在Chrome中我可以使iframe更大,但不能更小。 document.body.scrollHeight始终是最大的价值。
So if one big page sets #iframe.height = '620px', and someone clicks on a link to page with less content scrollHeight will remain at 620px instead of decreasing.
因此,如果一个大页面设置了#iframe.height ='620px',并且有人点击链接到页面的内容较少,则scrollHeight将保持在620px而不是减少。
What's the proper way of handling this in Chrome/Safari?
在Chrome / Safari中处理此问题的正确方法是什么?

Before you ask for the height of the document inside the iframe you should set the height of the iframe object to "auto". Something like this:
在要求iframe内部文档的高度之前,您应该将iframe对象的高度设置为“auto”。像这样的东西:
objIframe = document.getElementById('theIframeId');
objIframe.style.height = 'auto';
And now:
现在:
document.body.scrollHeight
returns the actual height of the document.
返回文档的实际高度。

Did you try using document.documentElement.scrollHeight
instead?
