How to get a value of an element by name instead of ID

How can I read the value of the field named item[tags][] from the following HTML document:

<ul id="mytags" class="tagit">
     <li class="tagit-choice">
       Acrylic
        <input type="hidden" name="item[tags][]" value="Acrylic" style="display: none;">
      </li>
     <li class="tagit-choice">
       Bath
     <input type="hidden" name="item[tags][]" value="Bath" style="display: none;">
     </li>
</ul>

You don’t have to use brackets to pass values as an array since name is not required to be unique across the page. Values with the same name attribute are passed on form submit as an array automatically.

I created an example filling JS array with elements values.

Markup:

<ul id="mytags" class="tagit">
     <li class="tagit-choice">
     Acrylic
     <input type="hidden" name="tags" value="Acrylic">
     </li>
     <li class="tagit-choice">
     Bath
     <input type="hidden" name="tags" value="Bath">
     </li>
</ul>

Code

var tags = new Array[];
$("#mytags").find("[name='tags']").each(
    function() {
        tags.push($(this).val());
    }
);
alert(tags.toString());
