推荐答案
如果您支持 IE，对于 Internet Explorer 8 及更高版本，此:
If you support IE, for versions of Internet Explorer 8 and above, this:
<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7" />
强制浏览器呈现为该特定版本的标准.IE7 及以下不支持.
Forces the browser to render as that particular version's standards. It is not supported for IE7 and below.
如果用分号分隔，它会设置不同版本的兼容性级别.例如:
If you separate with semi-colon, it sets compatibility levels for different versions. For example:
<meta http-equiv="X-UA-Compatible" content="IE=7; IE=9" />
将 IE7 和 IE8 渲染为 IE7，但将 IE9 渲染为 IE9.它允许不同级别的向后兼容性.但在现实生活中，您应该只选择其中一个选项:
Renders IE7 and IE8 as IE7, but IE9 as IE9. It allows for different levels of backwards compatibility. In real life, though, you should only chose one of the options:
<meta http-equiv="X-UA-Compatible" content="IE=8" />
这样可以更轻松地进行测试和维护.虽然通常更有用的版本是使用 Emulate:
This allows for much easier testing and maintenance. Although generally the more useful version of this is using Emulate:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />
为此:
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
它强制浏览器以最新版本的标准进行渲染.
It forces the browser the render at whatever the most recent version's standards are.
