How can I make dynamically created dependent select/dropdowns using just jQuery

I have a table with dynamically created rows, on each row I want to have 2 dropdowns/selects that are dependent on each other.
I have found 2 fiddles, the first is the exact output i want but the code is confusing and uses json. the second code is the easiest to understand but is not dynamic. Is there a way to make them work together?
// http://jsfiddle.net/C2xsj/5/ <----- this is the output i want but the code is kinda confusing for me
// https://jsfiddle.net/fwv18zo1/ <--- this has the simpler code
lets assume this is my table:
<INPUT type="button" value="Add Row" id="button"/>
<form id="myForm">
<TABLE id="addTable" >
<TR><TD>
<select id="selectCategory">
<option value="1">Fruit</option>
<option value="2">Animal</option>
<option value="3">Bird</option>
<option value="4">Car</option>
</select>
</TD>
<TD>
<select id="selectSubCategory" >
<option value="1">Banana</option>
<option value="1">Apple</option>
<option value="1">Orange</option>
<option value="2">Wolf</option>
<option value="2">Fox</option>
<option value="2">Bear</option>
<option value="3">Eagle</option>
<option value="3">Hawk</option>
<option value="4">BWM<option>
</select>
</TD></TR>
</TABLE>
</form>
when someone clicks the add row button, it creates a new row
using something similar to this all the options are coded into this function such as ():
$('#button').click(function() {
var table = $('#addTable');
table.append('<tr><td data-label="Task"><select class="ui fluid search dropdown" required><option value="1">Fruit</option><option value="2">Animal</option><option value="3">Bird</option><option value="4">Car</option></select><select class="ui fluid search dropdown" required><option value="1">Banana</option><option value="1">Apple</option><option value="1">Orange</option><option value="2">Wolf</option><option value="2">Fox</option><option value="2">Bear</option><option value="3">Eagle</option><option value="3">Hawk</option><option value="4">BWM<option></select></tr>');
}
so my issue is that since they cant all have the same id such as the ones in the fiddle, how i make the pair of selects on each row dependent

Here i used clone function. read comment on JS to know more.
$(document).on("change",".select1",function(){
var thisParent = $(this).parents("tr"); // detect the parent of the select1.
$(".select2",thisParent).find('option[value]').addClass('hidden'); // hide all option values.
$(".select2",thisParent).find('option[value="' + this.value + '"]').removeClass('hidden'); // show only values that match the 'select1' value.
});
$(".addNew").click(function(){ // clone button
$(".cloneThis").clone().appendTo("tbody"); // clone the class 'cloneThis' and append it into tbody.
$("tr:last").removeClass("cloneThis"); // remove 'cloneThis' class from the last appended child, so you can clone it again from the original one.
$("button:last").removeClass("addNew").addClass("removeThis").html("Remove"); // replace 'Add' with 'Remove' and add class 'removeThis' to be able to remove this tr.
});
$(document).on("click",".removeThis",function(){ // remove function.
$(this).parents("tr").remove(); // find this button parent and remove it.
});
table{
width:100%;
}
select, button{
width:30%;
}
.hidden{
display:none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tbody>
<tr class="cloneThis">
<td>
<select name="select1" class="select1">
<option value="1">Fruit</option>
<option value="2">Animal</option>
<option value="3">Bird</option>
<option value="4">Car</option>
</select>
<select name="select2" class="select2">
<option>Select type first</option>
<option value="1" class="hidden">Banana</option>
<option value="1" class="hidden">Apple</option>
<option value="1" class="hidden">Orange</option>

<option value="2" class="hidden">Bear</option>
<option value="3" class="hidden">Eagle</option>
<option value="3" class="hidden">Hawk</option>
<option value="4" class="hidden">BWM<option>
</select>
<button class="addNew">Add</button>
</td>
<tr>
</tbody>

how can i store two info on a single select and call them in separate textbox HTML/JS

<span id="s_home_country">
<select name="Home Country" id="home_country">
<option value="Select one" selected="selected">Select one</option>
<option value="h1">Home1</option>
<option value="h2">Home2</option>
<option value="h3">Home3</option>
<option value="h4">Home4</option>
</select>
</span>
and I have another data that i want to incorporate, when Home1 is selected, I want this to show 21-dec into another textbox automatically. and so on..
var Home_country = [
"21-Dec",
"01-Jan",
"01-Jan",
"01-Jan",
];

You could use an object and an event listener.
var home_country = {
"h1":"21-Dec",
"h2":"01-Jan",
"h3":"01-Jan",
"h4":"01-Jan",
};
var selectbox = document.getElementById('home_country');
var textbox = document.getElementById('home_country_date');
selectbox.addEventListener('change', function(e){
textbox.value = home_country[this.value]
})
<span id="s_home_country">
<select name="Home Country" id="home_country">
<option value="Select one" selected="selected">Select one</option>
<option value="h1">Home1</option>
<option value="h2">Home2</option>
<option value="h3">Home3</option>
<option value="h4">Home4</option>
</select>
</span>
<input type="text" id="home_country_date">

Please find below snippet just add another attribute data-attr1 and on change of select list find selected option and get its attribute with name data-attr1 and pass attribute's value to textbox
$("#home_country").on("change",function(){
$(".txtvalue").val($(this).find("option:selected").attr("data-attr1"));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span id="s_home_country">
<select name="Home Country" id="home_country">
<option value="Select one" selected="selected">Select one</option>
<option data-attr1="21-Dec" value="h1">Home1</option>
<option data-attr1="01-Dec" value="h2">Home2</option>
<option data-attr1="02-Dec" value="h3">Home3</option>
<option data-attr1="03-Dec" value="h4">Home4</option>
</select>
</span>
<input type="text" class="txtvalue" />

Add an event listener to your select input which outputs the relevant value from your array when an option is selected:
var el = document.getElementById('home_country');
var textbox = document.getElementById('your_textbox_el');
el.addEventListener('change', function(e){
if (e.target.value == 'h1') {
textbox.value = Home_country[0];
} else if (e.target.value == 'some other condition') {
// do something else
}
}

Unless I'm misunderstanding you, you can just put the values of the Home_country array inside the value properties of the options like so:
<span id="s_home_country">
<select name="Home Country" id="home_country">
<option value="Select one" selected="selected">Select one</option>
<option value="21-Dec">Home1</option>
<option value="01-Jan">Home2</option>
<option value="01-Jan">Home3</option>
<option value="01-Jan">Home4</option>
</select>
</span>
Now, when you do get the value of your select element, it will be the value in the array that you gave.

Set price using selection from dropdown menu

How can I set the price of items using dropdown menu lets say I have a dropdown menu with cars and trucks and depending on what the user picks the prices will vary how can I set the price of each one and update a box containing the price of each item.
<p><b>Truck: </b><select id="states" name="states" size="1">
<option>Please Choose</option>
<option value="F150">F150</option>
<option value="Ram1500">Ram1500</option>
<option value="chevy">chevy</option>
</select><br /></p><p><b>sports car: </b><select id="states" name="states" size="1">
<option>Please Choose</option>
<option value="mustang">mustang</option>
<option value="charger">charger</option>
<option value="camaro">camaro</option>
</select><br /></p>

Add extra attribute for price uzing data-* attributes, then on change get the value of this attribute and show it in the price field :
$('body').on('change', '#trucks', function(){
var selected_truck_price = $('option:selected', this).data('price');
$('#price').val(selected_truck_price);
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>
<b>Truck: </b>
<select id="trucks" name="trucks" size="1">
<option>Please Choose</option>
<option data-price="150" value="F150">F150</option>
<option data-price="1500" value="Ram1500">Ram1500</option>
<option data-price="2000" value="chevy">chevy</option>
</select>
<br/>
</p>
Price : <input name='price' id='price'/>
Hope this helps.

Populate a select with options selected from various selects - jquery

I´m not expert with javascript & jquery, and I just googled for many days but can´t find the answer.
How can I populate a select with options selected from other selects. For this example from the 1st select I choose Manchester, from 2nd I choose Bogota and the 3rd must be populated with Manchester and Bogota:
Select One <br>
<select id="city" name="city">
<option value="0"></option>
<option value="1">Manchester</option>
<option value="2">Paris</option>
<option value="3">Madrid</option>
</select><br>
Select 2 <br>
<select id="city2" name="city2">
<option value="0"></option>
<option value="4">Bogota</option>
<option value="5">Buenos Aires</option>
<option value="6">Quito</option>
</select><br>
Select 3, populated whit the options of the previous 2 selects <br>
<select id="street" name="street">
<option value="0"></option>
<option value="1">Manchester</option>
<option value="4">Bogota</option>
</select>
Many thanks for help me.

The following jQuery will refresh the street select list any time a change is made to a select with class refresh on it.
function refreshList() {
$('#street option').remove(); //Clear the dropdown
$('#street').append('<option value="0"></option>'); //Add the blank option
$('.refresh').each(function() { //Loop through every instance of class 'refresh'
var v = $(this).val(); //Selected Value
var t = $(this).find('option[value="' + v + '"]').text(); //Selected Text
if (v != 0) { //If value isn't blank, add option to Street
$("#street").append('<option value="' + v + '">' + t + '</option>');
}
});
}
$(document).ready(function() { //When the page loads
$('.refresh').change(function() { //Initialize a click-event listener for class 'refresh'
refreshList(); //Run above function
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Select One <br>
<select id="city" name="city" class="refresh">
<option value="0"></option>
<option value="1">Manchester</option>
<option value="2">Paris</option>
<option value="3">Madrid</option>
</select><br>
Select 2 <br>
<select id="city2" name="city2" class="refresh">
<option value="0"></option>
<option value="4">Bogota</option>
<option value="5">Buenos Aires</option>
<option value="6">Quito</option>
</select><br>
Select 3, populated with the options of the previous 2 selects <br>
<select id="street" name="street">
<option value="0"></option>
<option value="1">Manchester</option>
<option value="4">Bogota</option>
</select>

$('select#city').change(function() {
var $selected = $('option:selected', this).clone()//make a copy of selected option
$('#street').append($selected)//put the selected option in the 3rd select
})
$('select#city2').change(function() {
var $selected = $('option:selected', this).clone();//make a copy of selected option
$('#street').append($selected)//put the selected option in the 3rd select
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Select One
<br>
<select id="city" name="city">
<option value="0"></option>
<option value="1">Manchester</option>
<option value="2">Paris</option>
<option value="3">Madrid</option>
</select>
<br>Select 2
<br>
<select id="city2" name="city2">
<option value="0"></option>
<option value="4">Bogota</option>
<option value="5">Buenos Aires</option>
<option value="6">Quito</option>
</select>
<br>Select 3, populated whit the options of the previous 2 selects
<br>
<select id="street" name="street">
<option value="0"></option>
</select>
Use .clone() to make a copy of selected option
Description: Create a deep copy of the set of matched elements.
Then use .append() to insert the cloned element to 3rd select
Description: Insert content, specified by the parameter, to the end of each element in the set of matched elements.

Can't get jquery to set value of select input when value of first select changes

I'm trying to update the value of a select input when I change the value of another select input. I cannot get anything to happen on the page and want to make sure I don't have a syntax error or some other dumb thing in this code.
<div class="group">
<div class="inputs types">
<strong style="font-size:13px;">Category:</strong>
<select name="id" id="ctlJob">
<option value="1">Automotive</option>
<option value="2">Business 2 Business</option>
<option value="3">Computers</option>
<option value="4">Education</option>
<option value="5">Entertainment & The Arts</option>
<option value="6">Food & Dining</option>
<option value="7">Government & Community</option>
<option value="8">Health & Beauty</option>
<option value="9">Home & Garden</option>
<option value="10">Legal & Financial Services</option>
<option value="11">Professional Services</option>
<option value="12">Real Estate</option>
<option value="13">Recreation & Sports</option>
<option value="14">Retail Shopping</option>
<option value="15">Travel & Lodging</option>
</select>
<select name="type" id="ctlPerson"></select>
</div>
</div>
<script>
$(function() {
$("#ctlJob").change(function() {
//Get the current value of the select
var val = $(this).val();
$('#ctlPerson').html('<option value="123">ascd</option>');
});
});
</script>

Try using append instead:
$(function() {
$("#ctlJob").change(function() {
//Get the current value of the select
var val = $(this).val();
var ctl = $('#ctlPerson').append('<option value="123">'+val+'</option>')[0].options;
ctl.selectedIndex = ctl.length-1;
});
});
http://jsfiddle.net/J69q8/

I think you also need to set the 'selected' property. Add
$('#ctlPerson option[value="123"]').attr('selected', 'selected');
to the end of the script. You are currently adding the option to the select list, but are not changing the select list to show it.

<div id="test">
<select name="sel" id="sel">
<option name="1" id="1" value="1">Automotive</option>
<option name="2" id="1 value="2">Business 2 Business</option>
<option name="3" id="1 value="3">Computers</option>
</select>
<select name="sel2" id="sel2"></select>
</div>
<script>
$("#sel").change(function() {
var val = $(this).val();
$('#sel2').html('<option value="1">NEW</option>');
)};
</script>
this works fine for what you need to do.
it's something like what you have
