js动态添加表格

Answer 1

<script type="text/javascript">
var $ = function(id){
return document.getElementById(id);
}

//全选
function checkAll(target) {
var checkeds = document.getElementsByName("b_id");
for (var i = 0; i < checkeds.length; i++) {
checkeds[i].checked = target.checked;
}
}

//刷新行号
function refreshRowNo() {
var tbody = $("tbody");
for (var i = 0; i < tbody.rows.length; i++) {
tbody.rows[i].cells[0].innerHTML = i + 1;
}
}

//添加行
function AddRow() {
var tbody = $("tbody");
var row = tbody.insertRow(tbody.rows.length);
row.insertCell(row.cells.length);
row.insertCell(row.cells.length).innerHTML = '<input type="checkbox" name="b_id" />';
row.insertCell(row.cells.length).innerHTML = '<input type="text" name="name" />';
row.insertCell(row.cells.length).innerHTML = '<input type="text" name="number" />';
row.insertCell(row.cells.length).innerHTML = '<input type="text" name="price" />';
row.insertCell(row.cells.length).innerHTML = '<input type="text" name="sum" />';

refreshRowNo();
}

//删除行
function DelRow() {
var checkeds = document.getElementsByName("b_id");
var ischeck = false;
for (var i = checkeds.length - 1; i >= 0; i--) {
if (checkeds[i].checked) {
ischeck = true;
break;
}
}
if (ischeck) {
if (confirm("确定删除选中行?")) {
for (var i = checkeds.length - 1; i >= 0; i--) {
if (checkeds[i].checked) {
var index = checkeds[i].parentNode.parentNode.rowIndex;
$("tbody").deleteRow(index - 1);
}
}
refreshRowNo();
}
} else {
alert("请选中需要删除的行!");
}
}

//保存
function Save() {
var detail = [],
tbody = $("tbody");
for (var i = 0; i < tbody.rows.length; i++) {
var name = tbody.rows[i].cells[2].childNodes[0].value;
var number = tbody.rows[i].cells[3].childNodes[0].value;
var price = tbody.rows[i].cells[4].childNodes[0].value;
var sum = tbody.rows[i].cells[5].childNodes[0].value;
var item = name + "^" + number + "^" + price + "^" + sum;
detail.push(item);
}
var detailstr = detail.join("|");
$("detail").value = detailstr;
$("myform").submit();
}

</script>

<form name="myform" action="AddOrder.aspx" method="post">
<input type="hidden" id="detail" name="detail" />
<ul>
<li>采购单编号：<input type="text" id="CGDBH" name="CGDBH" /></li>

Answer 2

function addline()
{
var i=addrow.rows.length//获得表格长度
var unamej = "uname'+i+'" ;
var typej = "type'+i+'" ;
newline=document.all.addrow.insertRow();
newline.insertCell().innerHTML='<td><input name="unamej" readonly="true" size="11"></td>';
newline.insertCell().innerHTML='<td><input name="typej"readonly="true" size="11" /></td>';
}
