javascript自动生成表格行

//给指定的表格增加一行
function addRow(TableName)
{
var table=document.getElementById(TableName);
//添加一行
var tr_node = document.createElement("tr");
//设置列数组
var td_node =new Array(11);
var td_node_id =new Array("td_1","td_2","td_3","td_4","td_5","td_6","td_7","td_8","td_9","td_10","td_11");
var td_node_width =new Array("5%","10%","10%","10%","20%","20%","5%","5%","5%","5%","5%");

input_node_type =”Input”
//添加列
for(i=0;i<11;i++)
{
td_node[i] = document.createElement("td");
td_node[i].setAttribute("id",td_node_id[i]);
td_node[i].setAttribute("width",td_node_width[i]);
}
//添加列的内容和内容的属性，此处是新建一个Input框，并放入单元格中。
for(i=0;i<11;i++)
{
var input_node = document.createElement("input");
input_node.setAttribute("type",input_node_type);
input_node.setAttribute("id",td_node_id[i]+”Input”);
td_node[i].appendChild(input_node);
tr_node.appendChild(td_node[i]);
}

//将新建的行元素增加到表格中
table.appendChild(tr_node);
}
