Windows Internet Explorer 8 or later. In IE8 Standards mode, the value of the href attribute depends on the context of the reference to the attribute. When read as a Document Object Model (DOM) attribute, href returns an absolute URL. The value specified by the page author is returned when href is read as a content attribute, when the page is displayed in an earlier document compatibility mode, or when the page is viewed with an earlier version of the browser. For more information, see Attribute Differences in Internet Explorer 8.
