Safari 5 扩展
我正在尝试自学 Safari 5 扩展，而且我对 Web 开发总体来说还是个新手。查看示例代码，我发现：
<!DOCTYPE HTML>

</script>
我只是想知道，我正在看什么语言？我看到的函数和代码几乎看起来像 C 语言。 Apple 的文档说了解 HTML、javascript、CSS 和 HTMl5 会很有帮助，但我不确定他们的示例是用什么编写的。

If you point us to the sample you are referring to, that may help to clarify.If anything else looks unfamiliar - it may be "The Safari Extensions JavaScript API" which may contain some possibly unfamiliar looking JavaScript - from having a quick nose around - there doesn't seem to be any other technologies present.
<script>tags are used to allow inline javascript inside a HTML page - generally - w3schools is a good stop for concise explanations of HTML tags.<script>opens up the area in the page that will be interpreted as javascript code by the browser, while</script>signifies it has ended.So the

<!DOCTYPE HTML>is a HTML 5 doctype - 'an instruction to the web browser about what version of the markup language the page is written in'从我看来，它绝对是 HTML5 和 javascript 的混合体。
From what I see, it's definitely mixed HTML5 and javascript.
