validate dynamically added input types in a row of table

I am trying to validate the dynamically added input type field which are in a row of a table on button click event. The very first input type field has an ID so I am able to put a validation on it. But when I add more rows in the table dynamically , I don't know how to validate those input types of rows.


<table class="table table-bordered table-hover" id="tab_logic">

<th class="text-center">Channel Group Name
<th class="text-center">Description

<tr id='addr0'>

<td id="CGN">
<input type="text" id="channelgrpName" name='channelgrpName' placeholder='Channel Group Name' class="form-control" />
<td id="DES">
<input type="text" id="description" name='description' placeholder='Description' class="form-control" />

<tr id='addr1'></tr>

Jquery :

$(document).ready(function () {

var i = 1;
$("#add_row").click(function () {

$('#addr' + i).html("<td><input name='name" + i + "' type='text' placeholder='Channel Group Name' class='form-control' style='width:50%' /> </td><td><input name='mail" + i + "' type='text' placeholder='Description' class='form-control' style='width:50%'></td>");

$('#tab_logic').append('<tr id="addr' + (i + 1) + '"></tr>');
$("#delete_row").click(function () {
if (i > 1) {
$("#addr" + (i - 1)).html('');

$('#btnSave').click(function () {

// what should i to do here to validate dynamically added input types in row


Thanks in advance.

Just try this, if you need only check blanks

Like this:

$('#btnSave').click(function () {
  var validate = true;
    $('#tab_logic').find('tr input[type=text]').each(function(){
    if($(this).val() == ""){
        validate = false;
    alert("Form is validate")
    return true;// you can submit form or send ajax or whatever you want here
  } else {
    alert("please fill all the details")
    return false;
