向 HTML 元素添加额外属性是一种不好的做法吗? [英] Is it a bad practice to add extra attributes to HTML elements?

问题描述

有时我会为我的一些控件添加一个属性.喜欢:

Sometimes I add an attribute to some of my controls. Like:

<a href id="myLlink" isClimber="True">Chris Sharma</a>

我知道这不是一个有效的 html.但它在某些情况下对我有帮助.

I know it is not a valid html. But it helps me in some cases.

这是否被认为是一种不好的做法?我的一个朋友说，内网环境没问题，但在互联网上，搜索引擎可能会发现它不友好.

Is this considered as a bad practice? A friend of mine says that it is ok for Intranet environment but on internet it might not be find friendly by search engines.

如果这不是一个好的做法，最好的做法是什么?

If it is not a good practice, what are the best practicess?

谢谢

推荐答案

是的.这被认为是一种不好的做法.您的 HTML(如果是 4.0)将无法成功验证.相反，像这样添加一个类:

Yes. It is considered a bad practice. Your HTML (if it's 4.0) won't validate successfully. Instead, add a class like so:

<a href id="myLlink" class="climber" >...</a>

记住你可以有多个类:

<a href id="myLlink" class="climber girl pretty" >...</a>

您可以使用 CSS 或 JQuery 根据这些类选择内容，并根据组合选择性地覆盖样式:

And you can use CSS or JQuery to select out stuff based on these classes, and selectively override style based on the combinations:

a.climber             { color: brown; }
a.climber.girl        { color: red; }
a.climber.girl.pretty { color: pink; }
