html – Internet Explorer – 注释结束警告中的意外字符

Internet Explorer抱怨评论中的url中有两个破折号：

<!--
<iframe src="/file.PHP?var=AQJ--dsf"></iframe>
-->

HTML1416: Unexpected character in comment end. Expected “–>”.

如何摆脱这个荒谬的错误信息？

解决方法

从 the HTML 5 specification开始：

Comments must start with the four character sequence U+003C LESS-THAN SIGN,U+0021 EXCLAMATION MARK,U+002D HYPHEN-MINUS,U+002D HYPHEN-MINUS (<!--). Following this sequence,the comment may have text,with the additional restriction that the text must not start with a single “>” (U+003E) character,nor start with a U+002D HYPHEN-MINUS character (-) followed by a “>” (U+003E) character,nor contain two consecutive U+002D HYPHEN-MINUS characters (--),nor end with a U+002D HYPHEN-MINUS character (-). Finally,the comment must be ended by the three character sequence U+002D HYPHEN-MINUS,U+003E GREATER-THAN SIGN (-->).
