Everything works fine but when I post my data to a tcpdf newly created row didnt send, and mean time I want to add to the database also, please anyone knows the answer much appreciate. here is my codes
<script type="text/Javascript">
$(document).ready(function() {
$('#btnAdd').click(function() {
var num = $('.clonedSection').length;
var newNum = new Number(num + 1);
var newSection = $('#pq_entry_' + num).clone().attr('id', 'pq_entry_' + newNum);
newSection.children(':first').children(':first').attr('id', 'quantity_' + newNum).attr('name', 'quantity_' + newNum);
newSection.children(':nth-child(2)').children(':first').attr('id', 'rcptdelvry_' + newNum).attr('name', 'rcptdelvry_' + newNum);
newSection.children(':nth-child(2)').children(':first').attr('id', 'weight_' + newNum).attr('name', 'weight_' + newNum);
newSection.children(':nth-child(2)').children(':first').attr('id', 'volume_' + newNum).attr('name', 'volume_' + newNum);
newSection.insertAfter('#pq_entry_' + num).last();
$('#btnDel').prop('disabled','');
if (newNum == 5)
$('#btnAdd').prop('disabled','disabled');
});
$('#btnDel').click(function() {
var num = $('.clonedSection').length; // how many "duplicatable" input fields we currently have
$('#pq_entry_' + num).remove(); // remove the last element
// enable the "add" button
$('#btnAdd').prop('disabled','');
// if only one element remains, disable the "remove" button
if (num-1 == 1)
$('#btnDel').prop('disabled','disabled');
});
$('#btnDel').prop('disabled','disabled');
});
</script>

推荐答案
使用标准的提交按钮提交表单将在这种情况下不起作用。
提交按钮不会占用页面加载后创建的帐户中的表单域。
Submitting your form with a standard 'submit' button will not work in this case. The submit button does not take the formfields in account that are created after page load.
您必须编写一个序列化数据的提交处理程序，将它发送到服务器。
You'll have to write a submit handler that serializes your data and sends it to the server.
尝试这样的事情：
$('#yourFormID').on('submit', function(e) {
//prevent the default submithandling
e.preventDefault();
//send the data of 'this' (the matched form) to yourURL
$.post('yourURL', $(this).serialize());
});
服务器端你现在有$ _POST变量填充了键和值。
serverside you now have the $_POST variable filled with the keys and values.
您还可以检查在firebug或任何其他webdeveloper工具中发送的数据。
You can also inspect the data that is send in firebug or any other webdeveloper tool.
编辑：
我改变了你的小提琴来处理我的代码：
I have altered your fiddle to work with my code:
我已经包装了< ;表格>< / form> 围绕您的输入并添加< input type ='submit'/> 按钮
I have wrapped a <form></form> around your inputs and added a <input type='submit' /> button
