大家好，寻找一点帮助.....我目前正在尝试了解508指南对的影响的 过程我参与的网站，我对使用Javascript的 有疑问。该网站目前依赖于Javascript for 从一页到另一页导航 - 我找不到508 指南中的任何内容，例如6.3 WAI检查点符合AA标准： "确保在脚本，小程序或其他 程序对象被关闭或不受支持时页面可用。如果这不是 ，请提供有关替代可访问的等价信息 页面。 此限制是否不存在508合规？如果某个网站依赖于启用Javascript，那么该网站是否可以被视为符合508标准？ 非常感谢

Hi all, looking for a little bit of help.....I''m currently in the process of trying to understand the impact of the 508 guidelines on a web site that I am involved with, and I have a question surrounding the use of Javascript. The site currently relies on Javascript for navigating from page to page - I cannot find anything in the 508 guidelines like the 6.3 WAI checkpoint for AA compliance: "Ensure that pages are usable when scripts, applets, or other programmatic objects are turned off or not supported. If this is not possible, provide equivalent information on an alternative accessible page". Does this restriction not exist for 508 compliance? Can a site be considered 508 compliant if it relies on Javascript being enabled? Thanks

第508节不是很长 - 当然你看到第1194.22段（l）： （l）当页面使用脚本语言显示内容时，或者创建界面元素时，脚本提供的信息应 可以通过辅助技术读取的功能文本进行识别。 来自访问委员会的评论是 www.access-board.gov/sec508/g .. .194.22.htm＃（l）。 我有一个基于Javascript的下拉菜单，其中一个扩展点击 或键盘激活而不是鼠标悬停，来自 联邦机构508审核小组，每个弹出菜单上的项目都是 位于链接之后打开菜单并且是 可见时通过tab键可以穿过，但是当看不到时，它们被排除在选项卡 序列之外。 （使用CSS显示属性完成。）

Section 508 isn''t very long--surely you saw paragraph 1194.22(l): (l) When pages utilize scripting languages to display content, or to create interface elements, the information provided by the script shall be identified with functional text that can be read by assistive technology. Commentary from the Access Board is at www.access-board.gov/sec508/g...194.22.htm#(l). I''ve had a Javascript-based drop-down menu, one that expands on clicking or keyboard activation rather than mouseovers, pass muster from a Federal agency 508 review team, where the items on each pop-up menu were positioned right after the link that opened the menu and were traversible via the tab key when visible, but were left out of the tab sequence when invisible. (Accomplished using the CSS display attribute.)

您好Harlan ...感谢您的回复。我绝对看到那个段落， 但是没有具体的说明网站必须 功能，禁用Javascript。它谈到利用脚本 语言来显示内容，或者创建界面元素，但是这并不意味着网站必须在没有Javascript的情况下工作。它是 而不是渲染控件的Javascript，但它是处理点击超链接的Javascript 。这就是灰色区域 进来的原因以及为什么我要求网站可以符合508标准，如果它没有&b 使用Javascript禁用 再次感谢 Hi Harlan...thanks for the response. I absolutely saw that paragraph, but there is nothing specifically there that says that a site must function with Javascript disabled. It talks about "utilize scripting languages to display content, or to create interface elements", but this does not imply that the site must work without Javascript. It is not Javascript that is rendering the controls, but it is Javascript that is handling clicks on hyperlinks. That is where the grey area comes in and why I was asking can a site be 508 compliant if it doesn''t work with Javascript disabled Thanks again

第508条有一些详细的javascript指南，关于活动 不能使用，或者可以使用某些 （明确规定的）附带条件。 第508条与WCAG相比，以编程方式测试 要简单得多。请参阅 valet.webthing/access/ - Nick Kew

Section 508 has some detailed javascript guidelines, regarding events that can ror can''t be used, or those that can be used with certain (well-specified) provisos. Section 508''s guidelines are quite a lot easier to test programmatically than WCAG. See valet.webthing/access/ -- Nick Kew
