最近使用开发的过程中出现了一个小问题，顺便记录一下原因和方法--删除行
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>增长Table行</title>
</head>
<body>
<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("定确删除中选行?")) {
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("请中选要需删除的行!");
}
}
//保存
function Save(){
var detail = [],
tbody = $("tbody");
for (var i = 0;i<tbody.rows.length;i++){

var detailstr = detail.join("|");
