IE8 在 document.write 上挂起并显示“不支持此命令”

Question

For certain URLs (eg http://www.nyest.hu/iframe/240/10 ), IE8 (and older) never stops loading with the following error message: SCRIPT123: This command is not supported. The error line number points to a document.write command. IE9 and other browser load the page without problems.

Answer 1

Apparently this is because the page is served as XML, and there is no document.write in an XML document . Other browsers throw some sort of error at the document.write command too, but they handle the error better and do finish loading the page.
