jQuery Cloning and incrementing input, textarea, that has name, id and for

I'm still very new to jQuery, and would need help to how to increment 3 elements in this code.
name, id & for.
The name consist of products[0]category, id consist of checkbox[0], for consist of checkbox[0] which is for labels on the checkbox that id use.
I've tried searching for examples. But all them haven't found any good results that i could learn from unfortunately. So in the codes below, they're not there to increase increment as i have totally no idea what else i can do to increase increment numbering.
$(document).ready(function() {
let $append = $('#append');
// append location's data listing
$append.on('change', '.location', function(){
var value = $(this).val();
$('.location_id').val($('#locations [value="'+value+'"]').data('locationid'));
$('.loc_desc').val($('#locations [value="'+value+'"]').data('locdesc'));
});
// enable checkbox for serialnumbers
$append.on('change','.enable-serial', function(){
let $item = $(this).closest('.product-item');
let $checkbox = $item.find('.enable');
$checkbox.prop('disabled', !this.checked);
});
// ctrl for key in checkbox
$append.on('click', '.keyin-ctrl', function() {
let $container = $(this).closest('.product-item');
let $serial = $container.find('.serial');
$container.find('.display').val(function(i, v) {
return v + $serial.val() + ';\n';
});
$serial.val('').focus();
});
// ctrl for del textarea
$append.on('click', '.undo-ctrl', function() {
let $container = $(this).closest('.product-item');
$container.find('.display').val('');
});
// clone product, increment products[x]var
$('#add_product').on('click', function() {
var itemNo = $('.product-item').length + 1;
var index = $('.product-item').length;
var regex = /^(.+?)(\d+)$/i;
let $product = $append.find('.product-item.template')
.clone()
.show()
.removeClass('template')
.insertAfter('.product-item:last');;
$product.find('span').text('#' + itemNo);
$product.find(':checkbox').prop('checked', false);
$product.find('.enable').prop('disabled', true);
$product.find('input, textarea').val('');
$('#append').append($product);
});
// delete product, but remain original template intact
$('#delete_product').on('click', function(){
var itemNo = $('.product-item').length + 1;
let $product = $append.find('.product-item:last:not(".template")');
$product.remove();
});
});

So how do I actually achieve this to add increment to the NAME, ID and FOR my clones?
From the original template of products[0]variable to products[1]variable, checkbox[0] to checkbox[1]

If you want to increment either an ID, class, etc. you can't use .clone(), like the documentation warns:
Using .clone() has the side-effect of producing elements with
duplicate id attributes, which are supposed to be unique. Where
possible, it is recommended to avoid cloning elements with this
attribute or using class attributes as identifiers instead.
You'll have to do it "manually", following a very simple example below:
$( "#addrow" ).click(function() {
var count = $("#product").children().length;
$("#product").append("<input id='field[" + count + "]' type='text'>");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="product">
</div>
<input id="addrow" type="button" value="Add field">

How to add my ajax data to bootstrap4 cards

This is my part of html(ejs) file and I have multiple card forms(such as ID =myContent1, myContent2, myContetn3 ...) they receive ajax data when the i class=icon... is toggled. when the function(toggle) is activated, received ajax data mapping with myContent No. (ex. received ajax data ID 1 with myContent1 and 2 for myContent2 ... so on).

Collect data from form, stack in object and send it with AJAX using Vue

Trying to collect all the HTML data from my form, then to store it as an object and then send it using ajax request. Any ideas, please? Appreciate some help. I was trying with serialize's jquery, but read this in that way cannot be sent (to an API URL, no PHP) using ajax(post).
<form class="form" action="" method="" id="createProposal">
<div class="form-group">
<label class="col-md-12 control-label" for="asset-drop">Asset</label>
<div class="col-md-12">
<select id="asset-drop" name="asset-drop" class="form-control" >
<option value="1"> {{ this.assets[0] ? this.assets[0].name : '' }} </option>
<option value="2">{{ this.assets[1] ? this.assets[1].name : '' }}</option>
<option value="3">{{ this.assets[2] ? this.assets[2].name : '' }}</option>
</select>
</div>
</div>
<div class="form-group">

<div class="col-md-12">
<input id="amount-invest" name="amount-invest" type="text" placeholder="Currency" class="form-control input-md">
</div>
</div>
<div class="form-group">
<label class="col-md-12 control-label" for="description-input">Description</label>

<button type="submit" class="btn btn-primary create" v-on:click="formDataCreation">Create</button>
</div>
</form>

i suggest to create an object in your data section which you call proposal and bind your form to that object using v-model, i'm using single file component but it doesn't matter, you can fit that solution to your case :
<template>
<form class="form" action="" method="" id="createProposal">
<div class="form-group">
<label class="col-md-12 control-label" for="asset-drop">Asset</label>
<div class="col-md-12">
<select id="asset-drop" name="asset-drop" class="form-control" v-model="proposal.selectedAsset" >
<option :value="index" :key="index" v-for="(asset,index) in proposal.assets">{{asset}} </option>
</select>
</div>
</div>
<div class="form-group">
<label class="col-md-12 control-label" for="amount-invest">Amount</label>
<div class="col-md-12">
<input id="amount-invest" v-model="proposal.amount" name="amount-invest" type="text" placeholder="Currency" class="form-control input-md">
</div>
</div>
<div class="form-group">
<label class="col-md-12 control-label" for="description-input">Description</label>
<div class="col-md-12">
<textarea class="form-control" v-model="proposal.description" id="description-input" name="description-input"></textarea>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary cancel" v-on:click="hideCreatePropolsal">Cancel</button>
<button type="submit" class="btn btn-primary create" v-on:click="formDataCreation">Create</button>
</div>
</form>
</template>
<script>
export default {
data(){
return{
proposal:{
assets:[],
selectedAsset:'',
amount:'',
description:''
}
}
},
methods:{
hideCreatePropolsal(){
},
formDataCreation(){
/* $.ajax({
url: "yourUrl",
type: "POST",
data:this.proposal,
success: function (response) {
}});*/
}
}
};
</script>

Jsfiddle here

You have bound your radio button with $scope.choice.isSelected, you can set the value for this in controller or in ng-init it self.
Can you please add below two lines in your controller?
$scope.choice={};
$scope.choice.isSelected = "true";
Or in much better way, you can modify your tag like:
<li class="col-sm-6 text-center" ng-repeat="tab in tabs">
<label for="{{tab.url}}">
<input ng-class="{active:isActiveTab(tab.url)}" ng-click="onClickTab(tab)" type="radio" name="radio" id="{{tab.url}}" ng-model="tab.isRadioChecked" value="true">{{tab.title}}</label>
</li>
And in your controller.
$scope.tabs = [{
title: 'I am a new customer',
url: 'one.tpl.html',
isSelected: true,
isRadioChecked: "true"
}, {
title: 'I have an account',
url: 'two.tpl.html'
}];

You can do this simply by setting the checked attribute for the input. For example:
<input type="radio" checked> This is a radio button

activeform variable not updating

I have a Jquery function to activate and deactivate forms based off the current form. When I click on the submit button I can get the value of the activeform on the page load if I have it set to ID, but nothing off the second form. When I set it to class it doesn't seem to load any at all and I get no alert back when I click the submit. My jquery is as such:
<script>
$(document).ready(function() {
var activeform = "register";
$("#loginlink").click(function(e) {
var activeform = "login";
$("#login").show("blind", 1000);
$("#register").hide("blind", 1000);
})
$("#registerlink").click(function(e) {
var activeform = "register";
$("#register").show("blind", 1000);
$("#login").hide("blind", 1000);
})
$(".submit").click(function(e) {
e.preventDefault();
alert(activeform);
});
});
</script>
And the code for my forms:
<p>
<form id="register">
<div class='row'>
<div class="col-xs-4"></div>
<div class="col-xs-4">
<label for username><i class="fa fa-user"></i> Username</label>

Last but not least. Here's a fiddle. :)
https://jsfiddle.net/rm6j5da9/2/

You were recreating the activeform variable every time in the click event. remove the var keyword. you already declared that as a global variable inside the document ready scope.
$(function(){
var activeform = "register";
$("#loginlink").click(function(e) {
activeform = "login";
$("#login").show("blind", 1000);
$("#register").hide("blind", 1000);
});
$("#registerlink").click(function(e) {
activeform = "register";
$("#register").show("blind", 1000);
$("#login").hide("blind", 1000);
});
$(".submit").click(function(e) {
e.preventDefault();
alert(activeform);
});
});
Also you need to make sure that you have the submit css class on both the login and register buttons
Here is a working sample
