问题
I don't want to use a couple of javascript plugins for IE 6/7. But I want to use them for all other browsers.
How can I do it? Is there any way I can do it?
回答1:
From the Wikipedia article on conditional comments (modified to fit your version requirements):
<!--[if gt IE 7]><!-->
<p>This code displays on non-IE browsers and on IE 8 or higher.</p>
<!--<![endif]-->
The weird markup in the first line serves to make the markup standards compliant.

Your question would be better phrased as "Using conditional comments to exclude content from IE browsers" ;-)
Although CCs are most often used to provide additional content for IE, there is a variant that allows you to prevent IE from seeing content. With their usual arrogance, MS chose to call this "downlevel-revealed conditional comments" (because all other browsers are worse than IE in their world).
Something like
<![if !IE]><p>You are not using Internet Explorer.</p><![endif]>
should be all you need.
Note that describing this as a "Conditional Comment" is another example of MS's strange use of words to mean exactly what they choose them to mean rather than what everybody else means: the above works because it isn't actually a comment, so all browsers other than IE just assume you made a hideous mistake in your HTML and carry on parsing the content within.
This also means it will probably fail badly in XHTML served with the application/xhtml+xml content type, but that's another story.

There's a pretty good resource for such things at: http://www.javascriptkit.com/javatutors/conditionalcompile.shtml
This in conjunction with the @_jscript_version variable should help you achieve the desired result. (You'll have to Google "Version Information (Windows Scripting - JScript)" for the JScript -> IE version lookup as I'm only allowed to embed one link as a new user.) :-(
