可以将alt属性用于输入类型按钮 [英] can the alt attribute be used for an input type button
问题描述
我想问一下输入标签中的alt属性。
正如我在许多网站上发现的那样,当我们有一个类型为image的输入时,就会使用alt属性。
1 /它可以用于输入类型按钮?
< input type =buttonalt =myAction.myMethod/>
<2> /它的含义是什么?
- 否
- 它没有一个
唯一可以具有 alt
属性的输入是 type =image
它提供了一个文本替代方法,用于无法呈现图像(例如,由于浏览器不支持图像或因为用户使用屏幕阅读器软件而无法加载(通常是为了补偿视觉) )相关的残疾)。
I wanna ask about the alt attribute in an input tag. As I found on many sites, the alt attribute is used when we have an input with type image.
1/ Can it be used for an input type button?
<input type="button" alt="myAction.myMethod" />
2/ what is its meaning?
- No
- It doesn't have one
The only kind of input that can have an alt
attribute is type="image"
where it provides a text alternative for when the image can't be rendered (e.g. because it failed to load, because the browser doesn't support images, or because the user is employing screen reader software (usually to compensate for a vision related disability)).
