我创建了一个带有动态表的简单表单。此表行由用户输入值递增，因此每次创建新行时我都需要递增组合框或选择（选项），因此它应该类似于默认组合框值。注意：这个选择或组合框是列属性的一部分，记住行增量，但没有列。

第二个问题：

我想收集这个表的列数据或值，无论它的行数是多少，并使用 php 将其存储到 XAMPP 数据库中。我知道如何从单个表单中收集数据，但我不知道如何从动态表单中收集数据。

这是代码：

function AddRows()
{
var tableelement = document.getElementById("mytable")
var rows = document.getElementById("noofrows").value;
var tablerowcount = tableelement.rows.length;
var currowcount = tablerowcount;


for(i = 1; i < rows; i++) {

var row = tableelement.insertRow(currowcount);
var cellid = row.insertCell(0);
cellid.innerHTML = "<b>" + currowcount +"</b>";
var cellid2 = row.insertCell(1);


cellid2.innerHTML = "<input value='' id='" + currowcount +"_name' /> ";
var cellid3 = row.insertCell(1);
cellid3.innerHTML = "<input value='' id='" + currowcount +"_name' /> ";
var cellid4 = row.insertCell(1);
cellid4.innerHTML = "<input value='' id='" + currowcount +"_name' /> ";
var cellid5 = row.insertCell(1);
cellid5.innerHTML = "<input value='' id='" +currowcount +"_name' /> ";
var cellid6 = row.insertCell(1);
cellid6.innerHTML = "<input value='' id='" +currowcount+"_name' /> ";


var currowcountcurrowcount = currowcount++;

更改您的函数以获取每一行的选择并首先保存数据，您将所有输入和选择 id 更改为数组变量
ex id='1_name_Range[]'for range。还更改函数重命名代码以保存您所说的。使用数组变量保存在数据库中
