Do you mean You want to close modal popup on success? I will show my popup's JS, hope part of it will help you

define([
    'jquery',
    'Magento_Ui/js/modal/modal',
    'mage/cookies'
], function ($, modal) {
    'use strict';

    $.widget('devall.popupManager', {
        /**
         * creating popup
         */
        _create: function () {
            var self = this,
                popupOptions = {
                    responsive: true,
                    title: this.options.popupTitle,
                    buttons: false,
                    modalClass: 'popup-devnewsletter',
                    autoOpen: true,

                    /**
                     * setting a cookie
                     */
                    closed: function () {
                        self._setCookie();
                    }
                },
                contentOptions = {
                    success: this.options.successContent
                };

            if (!$.cookie('popup_cookie')) {

                if (this.options.popupEvent === 'Exit') {
                    $(document).mouseleave(function (e) {
                        e.preventDefault();
                        e.stopPropagation();
                        $(document).off('mouseleave');
                        modal(popupOptions, $('#popup-devnewsletter'));
                    });
                } else {
                    setTimeout(function () {
                        modal(popupOptions, $('#popup-devnewsletter'));
                    }, this.options.popupDelay * 1000);
                }
            }
            this.element.find('form').submit(function (e) {
                e.preventDefault();

                if ($(this).validation('isValid')) {
                    $.ajax({
                        url: $(this).attr('action'),
                        data: $(this).serialize(),
                        dataType: 'html',
                        type: 'POST',
                        showLoader: true,

                        /**
                         * Success function
                         */
                        success: function () {
                            $('#form-div-element').remove();
                            $('#devnewsletter-validate-detail').html(contentOptions.success);
                        }
                    });
                }
            });
        },

        /**
         * cookie function
         */
        _setCookie: function () {
            var expDate = new Date();

            expDate.setTime(expDate.getTime() + 1000 * 60 * 60 * 24 * 21);
            $.cookie('popup_cookie', 1, {
                expires: expDate
            });
        }
    });

    return $.devall.popupManager;
});
