Tag or element itself? Inner HTML? Why?
Giving the same name to different elements makes no sense.

I don't see how it could make any sense. Please see my comment to the question.

In all cases, you can easily navigate through DOM and find any elements by any features or their combination, or also by order of appearance, if you use jQuery:
http://api.jquery.com/category/selectors,
http://api.jquery.com/category/traversing,
https://api.jquery.com/each,
https://api.jquery.com/jquery.each (confusingly, under the same name, different each).

If you need to learn jQuery (highly recommended), please see:
http://en.wikipedia.org/wiki/JQuery,
http://jquery.com,
http://learn.jquery.com,
http://learn.jquery.com/using-jquery-core,
http://learn.jquery.com/about-jquery/how-jquery-works (start from here).

If you don't want to use jQuery, you can download its source code and see how things you are interested in are achieved. :-)

jQuery is a good suggestion, 5'ed.

Solution 1

You can use document.getElementsByName to get all elements with a specific name. This returns an array, over which you can iterate:

JavaScript

var elems = document.getElementsByName("v[]");
for (var i = 0; i < elems.length; i++) {
    elems[i].setAttribute('value', 'text');
}

This method does not exist. You'll have to write your own.
