我创建了带有动态表的简单表单。该表行根据用户输入值增加，因此每次创建新行时，我都需要增加组合框或选择（选项），因此它应该类似于默认组合框值。注意：此选择框或组合框是列属性的一部分，请记住行递增，但不包含列。
第二个问题：
我想收集此表的列数据或值（无论其行号是多少），并使用php将其存储到XAMPP数据库。我知道如何从单个表单收集数据，但是我不知道如何从动态表单收集数据。
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++;
}
}

最佳答案
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 = "<Select id='select' /><option name='option' value='CP'>Cash movement</option><option name='option' value='PV'>Payment Voucher</option> <option name='option' value='RV'>RV</option></Select> ";
var cellid3 = row.insertCell(1);
cellid3.innerHTML = "<Select id='select' /><option name='option' value='finance'>Finance Documents</option><option name='option' value='hr'>HR Documents</option><option name='option' value='test'>test</option</Select> ";
var cellid4 = row.insertCell(1);
cellid4.innerHTML = "<input value='' id='" + currowcount +"_name' /> ";

var currowcountcurrowcount = currowcount++;
}
}

更改功能以获取每一行的选择
并要保存数据，首先将所有输入和选择id更改为数组变量
ex id ='1_name_Range []'表示范围。功能也会改变
如您所说，重命名代码以进行保存。使用数组变量保存在数据库中
