magento2.4 – How to stop redirect on-click wishlist icon

My wishlist code:

<?php
/**
* Copyright © Magento, Inc. All rights reserved.
* See COPYING.txt for license details.
*/

/** @var MagentoWishlistBlockCatalogProductProductListItemAddToWishlist $block */
?>
<?php if ($block->getWishlistHelper()->isAllow()) : ?>


<a href="#"
class="action towishlist"
title="<?= $block->escapeHtmlAttr(__('Add to Wish List')) ?>"
aria-label="<?= $block->escapeHtmlAttr(__('Add to Wish List')) ?>"
data-post='<?= /* @noEscape */ $block->getAddToWishlistParams($block->getProduct()) ?>'
data-action="add-to-wishlist"
role="button">
<img class="whislist-icon product-id-<?php echo $block->getProduct()->getId();?>" src="https://magento.stackexchange.com/<?php /* @escapeNotVerified */ echo $block->getViewFileUrl("images/whislist_icon.jpg'); ?>" />
<span><?= $block->escapeHtml(__('Add to Wish List')) ?></span>
</a>

<?php endif; ?>
<?php
$_objectManager = MagentoFrameworkAppObjectManager::getInstance();
$storeManager = $_objectManager->get('MagentoStoreModelStoreManagerInterface');
$currentStore = $storeManager->getStore();
$mediaUrl = $currentStore->getBaseUrl(MagentoFrameworkUrlInterface::URL_TYPE_MEDIA);
$wishimage = $mediaUrl."after_added.jpg";
?>

<script>
require(('jquery'), function($){
jQuery.ajax({
url: '<?php echo $this->getUrl('addtowish/index/wishlist') ?>',
method: 'get',
dataType: 'json',
success: function(data) {
var wislistAddesCheckData = data;
var itemLenth = wislistAddesCheckData.items.length;
for(i=0;i<itemLenth; i++){
var wislistAddedProductId = wislistAddesCheckData.items(i).product_id;
$(".product-id-"+wislistAddedProductId).attr('src','<?php echo $wishimage ; ?>');
}
}
});
});
</script>
