javascript的可访问性 [英] accessability of javascript
问题描述
我想创建一个网页，当我将鼠标移到链接上时，
描述文本会显示在链接下方。例如。也许做一个输入
type =" text"链接下面的字段，并执行类似
onhover =" document.something.value =''what''" ;.
我会当下拉菜单设置为特定项目时，也希望页面的另一部分仅显示表单元素
。我可以轻松地使用display：none来完成这个
。
不幸的是，我不确定这样的东西是如何可以访问的。
事实上，它似乎是javascript和真正可访问的网站（例如，
甚至可以访问盲人和需要屏幕阅读器的人）只需
don''一起去。这是正确的还是有一些方法可以使一个
的网站具有交互性（好，排序）和可访问性，我不是很想知道它们是什么？

在档案馆搜索''工具提示''，这个主题有很多帖子。

网站既具有交互性（嗯，sorta）又可访问我不知道？
''JavaScript''和''access''并不是互相排斥的。
首先让网站完全可访问，然后将脚本添加到第二页

之一在创建
可访问网页时您必须考虑的事情是用户可能与他们的
计算机进行交互的方式。他们可能根本没有使用鼠标（通过选择或
无法成功操作）。

为什么不使用标题属性？更简单易用。

I''d like to make a webpage such that when I move my mouse over a link,
description text appears below the link. eg. maybe make an input
type="text" field below the links and do something like
onhover="document.something.value=''whatever''".
I''d also like to make another part of the page only show form elements
when a drop down menu is set to a particular item. I can do this
easily enough with display: none.
Unfortunately, I''m not sure how accessable doing stuff like this is.
In fact, it seems like javascript and truely accessable websites (eg.
accessable even to those who are blind and need screenreaders) just
don''t go together. Is this correct or is there some way to make a
website both interactive (well, sorta) and accessable that I''m not
aware of?

Search the archives for ''tooltip'', there are many posts on the subject.

''JavaScript'' and ''accessible'' aren''t mutually exclusive.
Make the website fully accessible first, then add script second to
enhance it for those who can take advantage of the scripting support
provided.

One of the things that you will have to think about when creating
accessible web pages is how the user may be interacting with their
computer. They may not be using a mouse at all (through choice or an
inability to successfully manipulate one).

Why not just use the title attribute? Simpler and accessible.
