How to set phtml file through html via Ajax call in Magento 2?

Sometime we need to set html data without load or set it via ajax.

Then create a module name : Magemonkey:Ajaxcall

create index.phtml in Magemonkey/Ajaxcall/view/frontend/templates/

<div id="ajaxresponsedata"></div>
<?php
$ajaxurl = $block->getAjaxUrl();
?>
<script type="text/x-magento-init">
        {
            "*": {
                "Magemonkey_Ajaxcall/js/call": {
                    "AjaxUrl": "<?php echo $ajaxurl; ?>",
                }
            }
        }
</script>

<?php

$ajaxurl = $block->getAjaxUrl();

{

"*": {

"Magemonkey_Ajaxcall/js/call": {

"AjaxUrl": "<?php echo $ajaxurl; ?>",

}

</script>

Create js file Magemonkey/Ajaxcall/view/frontend/web/js/

define([
    "jquery",
    "jquery/ui"
], function($){
    "use strict";
 
    function main(config, element) {
        var $element = $(element);
        var AjaxUrl = config.AjaxUrl;
        var CurrentProduct = productid;
         
        $(document).ready(function(){
            setTimeout(function(){
                $.ajax({
                    context: '#ajaxresponsedata',
                    url: AjaxUrl,
                    type: "POST",
                    data: {currentproduct:CurrentProduct},
                }).done(function (data) {
                    $('#ajaxresponse').html(data.output);
                    return true;
                });
            },1000);
        }); 
    };
    return main;
});

define([

"jquery",

"jquery/ui"

], function($){

"use strict";

function main(config, element) {

var $element = $(element);

var AjaxUrl = config.AjaxUrl;

var CurrentProduct = productid;

$(document).ready(function(){

setTimeout(function(){

$.ajax({

context: '#ajaxresponsedata',

url: AjaxUrl,

type: "POST",

data: {currentproduct:CurrentProduct},

}).done(function (data) {

$('#ajaxresponse').html(data.output);

return true;

});

},1000);

});

};

return main;

});

Create Index.php file in Magemonkey/Ajaxcall/Controller/Index/

<?php
namespace Magemonkey\Custom\Controller\Index;

use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\Controller\Result\JsonFactory;
use Magento\Framework\View\Result\PageFactory; 
 
class View extends Action
{
    public function __construct(Context $context, PageFactory $resultPageFactory, JsonFactory $resultJsonFactory)
    { 
        $this->_resultPageFactory = $resultPageFactory;
        $this->_resultJsonFactory = $resultJsonFactory;
 
        parent::__construct($context);
    }
    public function execute()
    {
        $result = $this->_resultJsonFactory->create();
        $resultPage = $this->_resultPageFactory->create();
        $currentProductId = $this->getRequest()->getParam('currentproduct');        
 
        $data = array('currentproductid'=>$currentProductId);
 
        $block = $resultPage->getLayout()
                ->createBlock('Magemonkey\Ajaxcall\Block\Index\Index')
                ->setTemplate('Magemonkey_Ajaxcall::index.phtml')
                ->setData('data',$data)
                ->toHtml();
 
        $result->setData(['output' => $block]);
        return $result;
    }
 
}

<?php

namespace Magemonkey\Custom\Controller\Index;

use Magento\Framework\App\Action\Action;

use Magento\Framework\App\Action\Context;

use Magento\Framework\Controller\Result\JsonFactory;

use Magento\Framework\View\Result\PageFactory;

class View extends Action

{

public function __construct(Context $context, PageFactory $resultPageFactory, JsonFactory $resultJsonFactory)

{

$this->_resultPageFactory = $resultPageFactory;

$this->_resultJsonFactory = $resultJsonFactory;

parent::__construct($context);

}

public function execute()

{

$result = $this->_resultJsonFactory->create();

$resultPage = $this->_resultPageFactory->create();

$currentProductId = $this->getRequest()->getParam('currentproduct');

$data = array('currentproductid'=>$currentProductId);

$block = $resultPage->getLayout()

->createBlock('Magemonkey\Ajaxcall\Block\Index\Index')

->setTemplate('Magemonkey_Ajaxcall::index.phtml')

->setData('data',$data)

->toHtml();

$result->setData(['output' => $block]);

return $result;

}
