js取得gridview中checkbox选中的值

测试好半天，才出来，checkbox在第一列，        for( i=1;i<document.all.GVmain.rows.length;i++)          {             var cb=document.all.GVmain.rows(i).cells(0).children(0);             if(cb.checked)             {                  temp0=document.all.GVmain.rows(i).cells(1).innerText;                  temp1=document.all.GVmain.rows(i).cells(5).innerText;                  temp2=document.all.GVmain.rows(i).cells(6).innerText;               }          }
