Yes, this template outputs standart button for submitting the form instead of pretty lookin one and notice that javascript is disabled.
For all the buttons to work properly without javascript they have to be placed in tempates on the following scheme (following is only pseudocode):
Code:
{if js enabled}
{include file="buttons/some_button.tpl"....}
{else}
{include file="submit_wo_js.tpl"...}
{/if}
But not all the buttons in original skin are implemented this way.
