When should I use the name attribute in HTML4/HTML5?

Question

I know by reading the W3C documention for HTML4.01 and HTML5 that the "name" attribute originally existed as a property of the <a> tag to permit people to link to an anchor point within a document.

However, now that all major browser venders allow linking to any html element within a document via the "id" attribute, is there still any real use for the "name" attribute? If so, how should I be using the "name" attribute?

Answer 1

The name attribute is required, I think, on input elements (and their friends)...

<input type="text" name="email" value="" />

Answer 2

One thing that comes to mind are radio buttons: you have to use name to specify which ones are part of the same group.

<form>
<input type="radio" name="sex" value="male" /> Male<br />
<input type="radio" name="sex" value="female" /> Female
</form>
