 // Arguments:
 //        id                 --> id of the to_display_element (REQUIRED)
 //        a_reference        -->    reference to the clicked a-tag (NOT REQUIRED)
 //        arr_words        --> words to be shown when clicking the link (NOT REQUIRED)
 //            arr_words[0]: word shown when 'closing'

 // Example: <a href="javascript:void(0);" onclick="return showHideAJAX('my_div_id', this, new Array('change','cancel'));">click me</a>
