I have just noticed that I am coding stuff like this:

<input type="text" ng-model="userName" id="userName" name="userName" />

And it occurs to me that I have access to the data though ng-data. I will never use getElementById() or getElementsByName().

Are theid= and name=just cluttering my HTML, or might I ever need them?

[Update] might they be of some use for automated testing?

    If you ever need them, add them when you need them. Commented Apr 4, 2016 at 9:36

    name might be useful for accessibility and automation. For example for a password manager. Commented Apr 4, 2016 at 9:41

Usually, the name attribute in input tags is used for form validation in the HTML scope. The errors for each element would be available in the form of: myFormName.MyElementName.$error.

For example, if your input tag has the 'required' attribute, the error flag would be accessible with myForm.myElement.$error.required

Here is an example that requires the name attribute (validate some field in a directive).

    And id can be useful for animation, jquery, etc. But no reason to include it if not used. Commented Apr 5, 2016 at 1:21
