我想post2.php
使用 POST 或 GET 方法将变量行与其他 HTML 表单变量一起发送。
下面的代码给出了一个错误:
Notice: Undefined index: row1 in C:\xampp\htdocs\PhpProject1\OtherUsableItems\post2.php on line 8
post1.php

<SCRIPT language="javascript">
function addRow(tableID) {

var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for(var i=0; i<colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[0].cells[i].innerHTML;
//alert(newcell.childNodes);
switch(newcell.childNodes[0].type) {
