How to remove table row if the form any of the input or select was empty?

I have a form as below, Here i am looking to remove tr row if the input text and select option was empty. and the show the table row if any of the input was not empty
As you can see the input was not empty, it was removing the entire row, it is possible check both are not empty then remove
By using Jquery
Note: table rows are dynamically adding
$(function(){
$("table#my_form tr td").each(function(){
$(this).find('input, select').each(function(){
if($(this).val()==""){
$(this).closest('tr.table_row').remove();
}
})
})
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form method="POST" action="">
<table id="my_form">
<tr class="table_row">
<td>
<input type="text" name="company" value="TCS" />
</td>
<td>
<select name="favorites" id="favorites">
<option value="">Select Favorites</option>
<option value="chess">Chess</option>
<option value="caroms" selected>Caroms</option>
<option value="ruby">Ruby</option>
</select>
</td>
</tr>
<tr class="table_row">
<td>
<input type="text" name="company" value="Deloite" />
</td>
<td>
<select name="favorites" id="favorites">
<option value="">Select Favorites</option>
<option value="chess">Chess</option>
<option value="caroms">Caroms</option>
<option value="ruby">Ruby</option>
</select>
</td>
</tr>
<tr class="table_row">
<td>
<input type="text" name="company" value="GOOGLE" />
</td>
<td>
<select name="favorites" id="favorites">
<option value="">Select Favorites</option>
<option value="chess" selected>Chess</option>
<option value="caroms">Caroms</option>
<option value="ruby">Ruby</option>
</select>
</td>
</tr>
</table>
</form>

To check all inputs, you could try something like this. As you mentioned, you are adding rows dynamically, so you would want some other event handler to check again for more bad rows. This code would run once on page load, and then again any time the '#removeBadRows' button is clicked.
$(function () {
removeBadRows();
$(document).on('click', '#removeBadRows', function () {
removeBadRows();
});
});
function removeBadRows() {
$("table#my_form tr").each(function () {
var badCount = 0;
var inputLength = $(this).find('input, select').length;
$(this).find('input, select').each(function () {
if ($(this).val() == "") {
badCount++;
}
});
if (badCount == inputLength) {
$(this).remove();
}
});
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form method="POST" action="">
<table id="my_form">
<tr class="table_row">
<td>
<input type="text" name="company" value="test" />
</td>
<td>
<select name="favorites" id="favorites">
<option value="">Select Favorites</option>
<option value="chess">Chess</option>
<option value="caroms" selected>Caroms</option>
<option value="ruby">Ruby</option>
</select>
</td>
</tr>
<tr class="table_row">
<td>
<input type="text" name="company" value="" />
</td>
<td>
<select name="favorites" id="favorites">
<option value="" selected>Select Favorites</option>
<option value="chess">Chess</option>
<option value="caroms">Caroms</option>
<option value="ruby">Ruby</option>
</select>
</td>
</tr>
<tr class="table_row">
<td>
<input type="text" name="company" value="GOOGLE" />
</td>
<td>
<select name="favorites" id="favorites">
<option value="">Select Favorites</option>
<option value="chess">Chess</option>
<option value="caroms">Caroms</option>
<option value="ruby" selected>Ruby</option>
</select>
</td>
</tr>
</table>
</form>

This could be the most simple method
$(function(){
$(document).on('change', '.table_row input', function(e) {
if($(this).val()==""){
$(this).closest('.table_row').remove();
}
});
});

validating all the html rows when the form is submitted

I am working on the html table where user can enter the details and click on submit button to submit the data to the backend.
I have 3 mandatory columns (Spring,Role,Project) which are mandatory to enter by the user before sending to the backend when clicked on submit button.
If user enters the data in first two rows and click on submit button, i want to validate if user has entered data in mandatory fields Sprint,Role and Project for each row and
if user has missed to enter data in mandatory fields then i want to show error message near that row saying "Please enter the mandatory fields". I am confused as how to show error message for each row if user has not entered data in the
madatory fields when user click on submit button after entering data in first 3 rows. Any inputs would be helpful.
I have total of 6 rows where user can enter details in all or few of them and click on submit button. Only i need to validate the rows and show error message near each row which has missing data in the mandatory fields.

jQuery.each($('tr:last td', this), function () {

tds += '</tr>';

$('tbody', this).append(tds);

Or you can see it here https://jsfiddle.net/f6xcqy2s/.
In that code the add button will show up in every rows, but i wanted the add button just show up in new row only, so there will be one button only. Do you know the way?

Hide the button like below.change the id of the button to a class and bind the button like below.it works perfectly
$('body').on('click','.insert-more',function(){
$("#mytable").each(function () {
var tds = '<tr>';
jQuery.each($('tr:last td', this), function () {
tds += '<td>' + $(this).html() + '</td>';
});
tds += '</tr>';
if ($('tbody', this).length > 0) {
$('tbody', this).append(tds);
} else {
$(this).append(tds);
}
});
$(this).hide();
})
here is the fiddle

you need to put add button outside the #mytable (table) so you can get your desire output only change html part as i pasted here.
<table id="mytable" class="table table-hover table-striped">
<thead>
<th>Check</th>
<th>Nama Klien</th>
<th>Nama File</th>
<th>Ukuran</th>
<th>Bahan</th>
<th>Jumlah</th>
<th></th>

let me know is it ok for you ?

Here first we create an event handler function and assign it to clickHandler. Then when we append the button into the table row after that we assign that click handler to the newly added button using the code as$("#insert-more").click(clickHandler);.
$( document ).ready(function() {
var clickHandler = function() {
$("#mytable").each(function () {
var tds = '<tr>';
jQuery.each($('tr:last td', this), function () {
tds += '<td>' + $(this).html() + '</td>';
});
tds += '</tr>';
if ($('tbody', this).length > 0) {
$('tbody', this).append(tds);
} else {
$(this).append(tds);
}
});
$(this).remove();
$("#insert-more").click(clickHandler);
};
$("#insert-more").click(clickHandler);
});

Hope this will help you.

Form validation with javascript reg expression

So, I have this form and all forms check if they're empty. However, I can't get the reg expression to validate that the name is using the correct syntax. Any clues to why this is, would be appreciated!

First of all document.getElementById.firstName should be changed to document.getElementById("firstName").
This part of code:
console.log(nameExp.test(document.getElementById("firstName").value));
if (!nameExp.test(document.getElementById("firstName").value)) {
alert("You need to enter a valid name");
document.getElementById("firstName").focus();
return false;
}
should be added just after var nameExp = /^[a-zA-Z]+$/; because the function returns false/true for if/else condition (if (relation.value == "")) and the code underneath it will never be called.
Moreover it's not common to use parenthesizes for return - Just use return true; or return false;
Also as #NeatNit said, you should use the proper onSubmit attribute for the form like so: onSubmit="return validate();".

The problem is that your return value is not actually going anywhere. Change:
<form id="form" onSubmit="validate();" action="" method="post">
Into:
<form id="form" onSubmit="return validate();" action="" method="post">

Hide input boxes based on drop down selection

I want a drop down menu at the top of the page to determine how many boxes are then showing on the page.
If the user selects 1, only 1 table shows
If the user selects 2, 2 tables show
I have added the code so hopefully it makes more sense

jsFiddle: http://jsfiddle.net/h3XLP/
very common to get jQuery answers but it's really not that comprehensive with standalone JavaScript
note: add the attribute style="display:none;" to the second table
var select = document.getElementsByTagName("select")[0];
select.onchange=function(){
if(select.value=="2"){
document.getElementsByTagName("table")[1].style.display="inline";
}else{
document.getElementsByTagName("table")[1].style.display="none";
}
}
however you should alternatively use below, as you may have more select and table elements in your document
http://jsfiddle.net/h3XLP/1/
var select = document.getElementById("selectnopuppies");
select.onchange=function(){
if(select.value=="2"){
document.getElementById("secondpuppytable").style.display="inline";
}else{
document.getElementById("secondpuppytable").style.display="none";
}
}
<p>Please select number of puppies:</p>
<p>
<select id="selectnopuppies">
<option value="1">1</option>
<option value="2">2</option>
</select>
</p>
<form id="form1" name="form1" method="POST" action="<%=MM_editAction%>">

Given that option 1 should show table 1, option 2 show table 1 and 2, and so on.
Try this:
$('#dropdown').change(function(){
var dropdown = $(this);
var tables = $('.tableSelector');
tables.hide();
tables.slice(0,dropdown.val()).show();
});
Working jsfiddle: http://jsfiddle.net/v5TTz/
I have tagged all tables with a css class "tableSelector", then everytime the dropdown changes value, I show the number of tables corresponding to the current value of the dropdownlist. This solution requires the tables to be positioned in the correct order in the DOM.
However, in my ears, this sounds like a case for templates, like jQuery templates or Hoganjs.

I have modified your code... It's working now... try this...
<html>
<head>
<title>Sample</title>
<script type="text/javascript">
function go()
{
var Count = document.getElementById("selCount").options[document.getElementById("selCount").selectedIndex].value;
if(Count==1)
{
document.getElementById("Puppy1").style.display = '';
document.getElementById("Puppy2").style.display = 'none';
}
if(Count==2)
{
document.getElementById("Puppy1").style.display = '';
document.getElementById("Puppy2").style.display = '';
}
}
</script>
</head>
<body>
<p>Please select number of puppies:</p>
<p>
<select onchange = "go()" id="selCount">
<option value="1">1</option>
<option value="2">2</option>

</p>
<form id="form1" name="form1" method="POST" action="<%=MM_editAction%>">

You can do something like this:
When you select 1st option, it will show you firSt table and for 2nd it will show you both tables.
$("table").hide();
$("select option").change(function(){
Val = $(this).val();
If(Val ==1) {
$("table")[0].show();
$("table")[1].hide();
} else {
$("table").show();
}
});

A little bit of javascript:
<script>
function showtable(o){
if(o.value==2){document.getElementById('table2').style.display='block';}
else{document.getElementById('table2').style.display='none';}
}
</script>
<p>Please select number of puppies:</p>
<p>
<select onchange="showtable(this)">
<option selected value="1">1</option>
<option value="2">2</option>
</select>
<table id='table2' width="330" border="0" style="display:none">

HTML Changes
<select onchange="showForm(this.options[this.selectedIndex]);">
Why it's needed ?
For listening the select box value change .
<table width="330" border="0" class="puppy">
Added class=puppy attribute for readability . For hiding table element will be generic and error prone.
Javascript Changes
function showForm(option){
//option user has selected.
var val = parseInt(option.value);
//form elements in a document.
var forms = document.getElementsByClassName("puppy");
for(var i=0,total=forms.length;i<total;i++){
var form = forms[i];
var display = form.style.display;
if(i<val && display == "none"){
form.style.display = "block";
}else if(i >= val && display != "none"){
form.style.display = "none";
}
}
}
