如何收集值(数据)动态添加的行(HTML表)?使用php &XAMPP - How to collect values (data) of dynamically added rows (HTML table) ? Using php & XAMPP

我创建了一个带有动态表的简单表单。这个表的行随着用户输入值的增加而增加，所以我需要在每次创建新行时增加组合框或select(选项)，所以它应该像默认的组合框值一样。注意:此选择框或组合框是列属性的一部分，请记住行增量，但没有列。

第二个问题:

我想收集这个表的列数据或值，无论它的行号是多少，并使用php将其存储到XAMPP数据库。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。

代码如下:

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++;

}
}

在函数中更改

以获取每行的选择为了保存数据首先将所有输入和选择id更改为数组变量
exid ='1_name_Range[]'for range。也改变了函数重命名代码保存，你知道你说的很好。使用数组变量保存在数据库
