我正在创建一个表单,它在单击按钮时添加了一个表格行,到目前为止它工作正常,但我希望在按钮单击生成的每一行旁边都有一个删除按钮,但不是在第一行。我搜索了很多博客,但没有任何人可以指导我这样做吗?我只是一个初学者。这是我的脚本:

session_start();

var i=1;
function addRow()
{
var tbl = document.getElementById('table1');
var lastRow = tbl.rows.length;
var iteration = lastRow - 1;
var row = tbl.insertRow(lastRow);
var firstCell = row.insertCell(0);
var el = document.createElement('input');
el.type = 'text';
el.name = 'name' + i;
el.id = 'name' + i;
el.size = 20;
el.maxlength = 20;
firstCell.appendChild(el);
var secondCell = row.insertCell(1);
var el2 = document.createElement('input');
el2.type = 'text';
el2.name = 'address' + i;
el2.id = 'address' + i;
el2.size = 20;
el2.maxlength = 20;
secondCell.appendChild(el2);
var thirdCell = row.insertCell(2);
var el3 = document.createElement('input');
el3.type = 'text';
el3.name = 'contactNum' + i;
el3.id = 'contactNum' + i;
el3.size = 20;
el3.maxlength = 20;
thirdCell.appendChild(el3);
frm.h.value=i;
i++;
}
