IE9 Support for HTML5 Canvas tag
提问by Shiraz Bhaiji
I am trying to test out the canvas tag, I started with this code:
我正在尝试测试画布标签，我从以下代码开始：
<html>
<canvas id="example" width="200" height="200">
This text is displayed if your browser does not support HTML5 Canvas.
</canvas>
</html>
In IE8 I get the message:
在 IE8 中，我收到消息：
This text is displayed if your browser does not support HTML5 Canvas.
I then installed IE9 but get the same error. Does IE9 support HTML5 canvas or not?
然后我安装了 IE9 但得到同样的错误。IE9 是否支持 HTML5 画布？

Extending the answer from gor, make sure that you have added following metadata.
<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>
This will force IE to use the latest mode as possible and users don't need to change the compatibility mode from developer tools.
这将强制 IE 尽可能使用最新模式，用户无需从开发人员工具更改兼容模式。

As far as I'm aware HTML 5 Canvas support is under development for IE9, unless it is already in the RC.. Perhaps not the best website to find out you could browse to html5testwith IE9 to see if it supports certain HTML 5 tags or not. As an alternative you can browse to caniusewhich should also give you alot of info regarding the HTML5 support of browsers .
据我所知，IE9 的 HTML 5 Canvas 支持正在开发中，除非它已经在 RC 中。也许这不是最好的网站，您可以使用 IE9浏览html5test以查看它是否支持某些 HTML 5 标签或不。作为替代方案，您可以浏览caniuse，它也应该为您提供大量有关浏览器 HTML5 支持的信息。

If you install the Google Chrome Frame Plugin [http://www.google.com/chromeframe][1], it upgrades IE6-9 to run the webkit rendering engine - along with HTML5/CSS3 support.
