Triptych Project开发者提议为HTML的button元素添加action和method属性，以明确区分按钮和链接在网页中的不同语义含义 [1]。按钮代表动作，在固定上下文中执行；而链接代表目的地，允许用户控制打开方式，如中键点击或在新标签页打开 [1]。
当前网页开发中存在语义混用的问题 [1]。开发者在实现状态转换导航时，常不正确地使用链接呈现为按钮样式，违反了HTML的语义规范 [1]。美国Web设计系统（USWDS）提供的class="usa-button"虽能将链接伪装成按钮的视觉样式，但无法实现真正的按钮行为 [1]。这一限制对无JavaScript网站构成挑战，例如英国政府网站等项目目前只能依赖链接实现导航功能 [1]。Button Actions提案旨在通过标准化属性设计，为网页无脚本实现和无障碍访问提供价值，其中DELETE请求是最常见的使用场景 [1]。
Developers are advancing a proposal within the Triptych Project to standardize how buttons and links function in HTML by introducing new action and method attributes to the button element [1]. The initiative aims to clarify the semantic distinction between buttons, which represent actions to be performed, and links, which represent destinations users can navigate to [1].
Currently, the lack of native button functionality for navigation tasks has led developers to misuse links styled as buttons, compromising HTML semantics [1]. Websites without JavaScript—including government sites like those in the United Kingdom—must rely solely on links to implement navigation, despite buttons being the more appropriate semantic choice for such interactions [1]. The U.S. Web Design System offers a workaround through the class="usa-button" convention to visually transform links into buttons, but this approach cannot deliver genuine button behavior [1].
The proposed feature addresses practical use cases where buttons would traditionally require scripting to function, with DELETE requests cited as among the most common scenarios requiring this capability [1]. By enabling buttons to specify actions and methods directly in HTML, the proposal would support both semantic correctness and accessibility improvements, while also enabling truly no-script implementations of interactive features [1].
