如何评论IE条件评论？

Question

I'm just wondering if it's possible to comment out IE conditional comments themselves (for testing purposes)? The following does not work:

<!-- <!--[if IE 7]> some code <![endif]--> -->

Thanks in advance! flexx

Answer 1

No, it isn't possible.

SGML/HTML/XML/XHTML comments cannot be nested.

Answer 2

我想你可以插入一些东西使它们无效：

<!--\[if IE 7]> some code <!\[endif]-->

Answer 3

<!--[if IE 70]> some code <![endif]-->

:)

Answer 4

If I were you I'd use a template systems like Template Toolkit and then Just include or exclude the comment conditionally, based on some variable you could set at runtime.

Answer 5

如果您通过.asp或aspx等服务器发送它，那么您当然可以在服务器端发表评论。

Answer 6

You can't nest comments, but you can comment them out by adding an extra <!-- to the beginning. Your example from above changes from <!-- <!--[if IE 7]> some code <![endif]--> --> to <!-- <!--[if IE 7]> some code <![endif]--> . Just take out the extra --> and it should comment out that pesky conditional.
