<script>

//删除当前td标签

 function del_accessory(tablename){

for(var i=2;i<3;i++){

//得到table第二行(第二个tr)的内容

            var tab = document.getElementById(tablename).rows[(i)].cells[0].innerHTML;

if(tab != "" && i != 3){

//得到td

var td = document.getElementById(tablename).rows[(i)].cells[0]

//将当前td删除

td.removeNode(td);

 

 

//得到td的第0个元素

//var fob0 = td.childNodes[0];

//得到td的第1个元素

//var fob1 = td.childNodes[1];

//删除第0个元素

//fob0.parentNode.removeChild(fob0);
