关于复制的内容，里面控件name属性如何定义？

页面中table原有的内容，第一行生成的控件name为a1，a2
第二行为b1，b2，b3通过使用函数addrow，新生成的每一行中，控件的name如何定义？？？？？？新生成每一行name最好不一样，因为下面要执行@$_GET，还有在MySQL命令，能使循环方便些。

  1.   

    用个数组存名字function   addRow(){   
      var   row   =   document.getElementById("ModelRow"); 
      var   ib    =   document.getElementById("insertBefore");     
      var   n     =   row.cloneNode(true);
    //加入n.name=array[n];
      n.setAttribute("id",null);  
      row.parentNode.insertBefore(n,ib);
      }
      

  2.   

    HTML改动:
    调整控件的名字 a2,b2,c2
    给table 一个id="tb"

    楼上的高手再看看，就是默认的是两组数据，点“+”可能增加若干组，然后那段php代码可能要用循环。<html>
