It’s possible with simple trick though, found the solution.
For anyone who has this issue, here is the solution.
Install this plugin,
https://wordpress.org/plugins/woocommerce-quick-buy/
Edit this file : wp-content/plugins/woocommerce-quick-buy/includes/js
/frontend.js
just add this line into the file :
jQuery('body').off('submit');
so your modified file will become
jQuery(document).ready(function () {
jQuery('.wcqb_button').click(function () {
jQuery('body').off('submit');
var product_id = jQuery(this).attr('data-product-id');
var product_type = jQuery(this).attr('data-product-type');
var selected = jQuery('form.cart input#wc_quick_buy_hook_' + product_id);
var productform = selected.parent();
productform.append('<input type="hidden" value="true" name="quick_buy" />');
var submit_btn = productform.find('[type="submit"]');
var is_disabled = submit_btn.is(':disabled');
if ( is_disabled ) {
jQuery('html, body').animate({
scrollTop: submit_btn.offset().top - 200
}, 900);
} else {
productform.find('[type="submit"]').click();
}
});
jQuery('form.cart').change(function () {
var is_submit_disabled = jQuery(this).find('[type="submit"]').is(':disabled');
if ( is_submit_disabled ) {
jQuery('.wcqb_button').attr('disabled', 'disable');
} else {
jQuery('.wcqb_button').removeAttr('disabled');
}
})
});
.
