<script type="text/javascript">
function Tad(){
var tables = document.getElementsByTagName("table");
  
for(var i=1;i<tables[0].rows.length;i++){
alert(tables[0].rows[i].cells[1].firstChild.nodeValue);
  }
}


</script>

    不能  <TR class="hui66">
     
     这个是CSS吧   但是我把他全删除了 也没用啊  你等我在试试吧

    恩..CSS 那个我都给删了 你就省基本标签就行 看看好使吗?

     for(var i=0;i<checkboxs.length;i++)改成   for(var i=0;i<oTable.rows.length;i++)就可以了还有 那个a是 a=i; 而不是a=i-1;
    循环那块应该是
     for(var i=0;i<oTable.rows.length;i++){
     
               if(oTable.rows[i].cells[4].innerHTML.match("Connected")){
                         a = i;
     
                         alert(oTable.rows[i].cells[4].innerHTML.match("Connected"));
                         if(checkboxs[a].disabled==false){
                             checkboxs[a].checked = false;
                             checkboxs[a].disabled = true;
                         }else{                      
                            checkboxs[a].disabled = false;
                         }    
                }

    因为table的row下标从1开始,而checkbox的下标从0开始,把oTable.rows[i].cells[4].innerHTML.match("Connected")改为oTable.rows[i+1].cells[4].innerHTML.match("Connected")即可
