Hello,

I've noticed a lot of websites with form(s) containing input fields whose "name" attribute is specified even if it isn't used for styling or scripting purpose!

Moreover, according to the official document about the form in HTML document ...

name = cdata [CI] This attribute names the element so that it may be referred to from style sheets or scripts. Note. This attribute has been included for backwards compatibility. Applications should use the id attribute to identify elements.

So, my question is: should this attribute used only for styling and scripting purposes?

Thanks in advance!


EDIT: In particular, could be avoided the use of this attribute with input fields of "text" type (when there aren't no styling or scripting purposes)?


EDIT 2: So, you have almost confirmed what I had thought about: the "name" attribute will be deprecated in further HTML specifications/standards!!!??? It is still "alive" only for backwards compatibility ... in some cases can be avoided but there are still some cases (such as the radio button) where it is necessary!

A: 

IIRC older browsers use name in place of ID, that's why it's normally included.

There are differences between id and name attributes. An id is applicable to any element in the HTML document while a name is relevant for input fields only. An id is required by standard to be unique in a page (though not necessarily followed in all web pages). Different elements may have same name though. One particular case comes into mind is the radio button. All radio buttons should have the same name and the value of the one selected would be given back to the form. So you can see that name still has significance in HTML form processing.

I have seen in automatic HTML form generation systems (like zope.formlib), that id and name attributes both are automatically generated for different types of input widgets. Such automatic form generation systems take proper care of all the nuances associated with differences in id and name attributes. They also do things like generating a hidden input element for each checkbox element. So wherever possible, I try to use some sort of automatic HTML form generation mechanism and let it take care of the issues involved.

Thanks, the radio button is a good example! However, I don't agree with automatic generation of markup code!

The name attribute is the notation to reference specific elements within the scope of a webpage through non-DOM Javascript:

document.forms['your_form'].elements['aa']

The id attribute for the element needs to be set with the same value for the following to work:

document.getElementById('aa')

My understanding is that when Netscape created Javascript, it used the name attribute. The HTML spec however decided to go with id, but kept name for backwards compatibility. IME, using the name attribute was required for Internet Explorer 6 support because the javascript engine in IE wouldn't read the id attribute - only the name though both were defined.

...could be avoided the use of this attribute with input fields of "text" type (when there aren't no styling or scripting purposes)?

If you don't have any javascript attached to the text fields, yes - they would be unnecessary.

Thanks! So you have confirmed what I had thought about: the "name" attribute in future will be probably deprecated!!!???

@BitDrink: Once we're rid of Internet Explorer 6, the deprecation should be reality.
OMG Ponies
:-D Yes, you are completely right!!!

I think you'll find almost every site will have inputs with the name attribute. I don't see it going away anytime soon.

The name attribute specifies a name for an input element.

The name attribute is used to identify form data after it has been submitted to the server, or to reference form data using JavaScript on the client side.

Note: Only form elements with a name attribute will have their values passed when submitting a form.

You have underlined a good point! However, my question comes out after I've seen some input fields that contain this attribute (and some others) where is not necessary ... so I think that this is a bad developing practice, a matter of redundancy!

It depends, if the input is in a form and you don't want/need to submit the data, don't use the name attribute. If the input is outside of a form, you don't need it at all. If it's going to be deprecated? I really doubt it, but it's already an optional attribute so you only need to use it if you want to (or if you want to pass data to the server).
