| **粘性激活**（或“粘性用户激活”）是一种表示用户按下了按钮、移动了鼠标、使用了菜单或执行了其他用户交互窗口状态。 | ||
|
|
||
| 如果用户当前正在与页面交互或自页面加载以来完成了触摸、指针或键盘交互，则该页面被视为“用户已激活”。如果某个页面被设置了黏性激活状态，则在会话期间不会该状态被重置（与{{Glossary("Transient activation", "瞬态激活")}}不同）。 | ||
|
|
||
| 参见[由用户激活控制的特性](/zh-CN/docs/Web/Security/User_activation)以查看需要*粘性激活*的 API 示例。 | ||
|
|
||
| 参见 {{domxref("UserActivation.hasBeenActive")}} 属性以通过编程方式获取当前窗口的粘性激活状态。 | ||

| **样式表**是一组用于控制网页或文档布局和设计的 CSS 规则。*内部*样式表放置在网页文档的 {{htmlelement("head")}} 中的 {{htmlelement("style")}} 元素内，而*外部*样式表则放置在单独的 `.css` 文件中，并通过在文档头部的 {{htmlelement("link")}} 元素引用外部样式表文件的方法来将其应用于文档。 | ||
|
|
||
| 通常推荐使用外部样式表，因为这允许你在一个地方控制多个页面的样式，而无需在每个页面上重复 CSS。 | ||

| title: 提交按钮 | ||

|
|
||
| **提交按钮**是一种可用于提交{{HTMLElement("form", "表单")}}的 HTML {{Glossary("element", "元素")}}。原生的提交按钮元素包括： | ||
|
|
||
| - {{HtmlElement("button")}}（其默认 `type` 为 `"submit"`） | ||
| - {{HtmlElement('input/submit', '<input type="submit">')}} | ||
| - {{HtmlElement('input/image', '<input type="image">')}} | ||
|
|
||
| 除了提交表单，提交按钮还可以影响表单的行为和发送的数据。 | ||
|
|
||
| ## 重写表单的行为 | ||
|
|
||
| 提交按钮可以通过各种属性重写表单的提交行为： | ||
|
|
||
| - `{{HtmlElement("button#formaction", "formaction")}}`：覆盖表单的 [`action`](/zh-CN/docs/Web/HTML/Element/form#action) 属性。 | ||
| - `{{HtmlElement("button#formenctype", "formenctype")}}`：覆盖表单的 [`enctype`](/zh-CN/docs/Web/HTML/Element/form#enctype) 属性。 | ||
| - `{{HtmlElement("button#formmethod", "formmethod")}}`：覆盖表单的 [`method`](/zh-CN/docs/Web/HTML/Element/form#method) 属性。 | ||
| - `{{HtmlElement("button#formnovalidate", "formnovalidate")}}`：覆盖表单的 [`novalidate`](/zh-CN/docs/Web/HTML/Element/form#novalidate) 属性。 | ||
| - `{{HtmlElement("button#formtarget", "formtarget")}}`：覆盖表单的 [`target`](/zh-CN/docs/Web/HTML/Element/form#target) 属性。 | ||
|
|
||
| ## 表单数据条目 | ||
|
|
||
| 如果提交按钮是 {{HtmlElement("button")}} 或 {{HtmlElement('input/submit', '<input type="submit">')}} 并且具有 `name` 属性，表单数据集将包括其 `name` 和 `value` 的条目。 | ||
|
|
||
| 如果提交按钮是 {{HtmlElement('input/image', '<input type="image">')}}，表单数据集将包括用户点击的 X、Y 坐标的条目（如 `x=100&y=200` 或 `buttonName.x=123&buttonName.y=234`）。 | ||

| title: 语法 | ||

| 语法指定了组成正确结构代码所需的{{Glossary("character", "字符")}}的组合和顺序。语法通常包括语法规则和适用于书写的规则，例如 Python 中的缩进要求。 | ||
|
|
||
| 语法因语言而异（例如，{{Glossary("HTML")}} 和 {{Glossary("JavaScript")}} 的语法不同）。尽管语言在语法方面可能有一些相似之处，比如 JavaScript 和 Python 语言都有一条“操作数 运算符 操作数”语法规则，但这并不意味着两种语言的语法相似。 | ||
|
|
||
| 语法既适用于编程语言（对计算机的命令），也适用于标记语言（文档结构信息）。 | ||
|
|
||
| 语法只管顺序和结构；指令还必须*有意义*，这就是{{Glossary("semantics", "语义")}}的范畴。 | ||
|
|
||
| 代码必须符合正确的语法才能正确{{Glossary("compile", "编译")}}，否则会出现{{Glossary("syntax error", "语法错误")}}。即使是小错误，比如缺少一个括号，也会导致源代码无法成功编译。 | ||
|
|
||
| 如果框架具有“干净”的语法，则表示它们生成简单、可读、简洁的结果。如果代码库使用“很多语法”，则意味着它需要更多字符来实现相同的功能。 | ||

| TLD（_顶级域_）是在互联网的层次结构 DNS（域名系统）中最通用的 {{Glossary("domain", "域名")}}。TLD 是{{Glossary("domain name", "域名")}}的最后一个组成部分，例如，`developer.mozilla.org` 中的 `org`。 | ||
|
|
||
| {{Glossary("ICANN")}}（互联网名称与数字地址分配机构）指定组织来管理每个 TLD。根据管理组织可能有多严格，TLD 通常作为网站的用途、所有权或国籍的线索。 | ||
|
|
||
| 考虑一个示例的互联网地址：`https://developer.mozilla.org`。这里的 org 是 TLD；mozilla.org 是二级域名；developer 是子域名。所有这些组成了一个完全限定域名；添加 https\:// 使其成为一个完整的 URL。 | ||
|
|
||
| {{Glossary("IANA")}} 今天区分以下顶级域组： | ||
|
|
||
| - 国家代码顶级域（ccTLD） | ||
| - : 为国家或地区建立的两个字符域。例如：美国的 _.us_。 | ||
| - 国际化国家代码顶级域（IDN ccTLD） | ||
| - : 非拉丁字符集（例如阿拉伯语或中文）的 ccTLD。 | ||
| - 通用顶级域（gTLD） | ||
| - : 具有三个或更多字符的顶级域。 | ||
| - 无赞助顶级域 | ||
| - : 直接根据 ICANN 为全球互联网社区建立的政策运作的域，例如“com”和“：edu”。 | ||
| - 赞助顶级域（sTLD） | ||
| - : 这些域由私人组织提出并赞助，根据社区主题概念决定申请者是否有资格使用 TLD。 | ||
| - 基础设施顶级域 | ||
| - : 这个组由单个域——{{Glossary("ARPA", "地址和路由参数区")}}（ARPA）——组成。 | ||
