I've been known to get quite carried away with naming form elements as
nested arrays, often dynamically generated, and have found that using the
elements[] property of the form object works best for me. To access the
elements of the form named 'example_form'

<form action='x.php' name='example_form' method='post'>
<input type='hidden' name='userdata[hidden_group_1][first]' value='one'>
<input type='hidden' name='userdata[hidden_group_1][second]' value='two'>
<input type='hidden' name='userdata[hidden_group_2][third]' value='three'>
<input type='hidden' name='userdata[hidden_group_2][fourth]' value='four'>
</form>

use a javascript like

document.example_form.elements['userdata[hidden_group_2][third]'].value
