在HTML元素上使用非W3C有效属性

Question

What is your opinion about using non valid attributes on html elements for easier jQuery selectors etc ?

Eg.

<div name="myDiv"></div>

According to Visual Studio the name attribute is not valid for a div element.

Answer 1

I would recommend using "dummy" classes (and the jQuery class selector) to disambiguate naming of html elements. 100% compliant approach.

Class Selector (“.class”)

Answer 2

If you absolutely must , use the data pseudo-namespace; such as data-id or data-name .

Edit: Using the data pseudo-namespace is far better than perverting the usage of an existing attribute like class or id .

Answer 3

如果您仍然想保持与w3c的兼容性，则w3c允许title属性提供额外的信息，您可以使用它们来代替添加新的非标准属性。
