在中继器中，当我单击row1它时，它正在展开，当我单击 时row2，它row1正在折叠并row2正在展开。

但是，当我单击 row1（类标题）时，它正在扩展，但是当我再次单击 row1 时，它也必须折叠。那是行不通的。

    <style>
   .header { font-size: larger; font-weight: bold; cursor: hand; cursor:pointer;
       background-color:#cccccc; font-family: Verdana; }
   .details { display:none; visibility:hidden; 
         font-family: Verdana; }
    </style>
 <SCRIPT>
     function ToggleDisplay(id) {
    var allDetails = document.getElementsByClassName('details');
    var detaisToShow = document.getElementById('d' + id);
    for(var i=0; i<allDetails.length; i++){
        allDetails[i].style.display = 'none';
        allDetails[i].style.visibility = 'hidden';
    }
    detaisToShow.style.display = 'block';
    detaisToShow.style.visibility = 'visible';
    }

 </SCRIPT>
