document.documentElement is a reference to the root element of the document, usually the <html> tag. document.documentElement是对文档根元素的引用，通常是<html>标记。
document.all is a collection type, containing an enumeration of all the children tags within the document. document.all是一个集合类型，包含document.all中所有子标记的枚举。 It's IE specific and should be avoided for cross-browser scripts. 它是IE特定的，应该避免跨浏览器脚本。
document.documentElement is DOM Level 2, so should work in pretty much any major browser these days. document.documentElement是DOM Level 2，所以现在几乎可以在任何主流浏览器中使用。
