Input buttons and <a> class buttons do not work

Question

I’m using a plugin from a modal window to make a simplified shopping cart for the customer, only the buttons select the paypal or paypal as a form of payment do not work at all. If I click the button it does not redirect to any page.

Link in the codepen with the codes: https://codepen.io/flashpremium/pen/PjwoOd/ and the result on the page: https://codepen.io/flashpremium/live/e613565ea5ed20101bdcf43dca22266b

I identified that the following line of javascript code below is making the buttons inside the modal window not work. What I do to fix?

 self.$target.on('click', function(e) { self.hide(e) });
      self.$el.on('click', function(e) { self.show(e) }); 
    },

Answer 1

I believe whatever’s keeping your buttons from working, in fact, is e.preventDefault();.

I would suggest, since the functionality of the buttons is "disabled", that you return the functionality to them using jQuery:

$(".btn-checkout-pagseguro").click(function() {
    $("#checkOutPag").submit();
});

Giving a id to the form:

<form target="pagseguro" action="https://example.com/"
  method="post" id="checkOutPag"> <!-- adicionando esse id -->

But just commenting on the e.preventDefault(); will make your Modal work - has some other functionality in it that requires blocking of standard events?

(function($) {
	$.modal = function(el, options) {
		this.options = options;
		this.$el = $(el);
		this.$target = $(el.hash || this.$el.attr('data-target'));
		this.$backdrop = $('.modal-backdrop');

		if (this.$target.length) {
			this.$el.data("modal", this);
			this.init();
		}
	};

	$.modal.prototype = {
		init : function() {
			var self = this, settings, backdrop = $('<div/>').addClass(
					'modal-backdrop fade');

			if (!self.$backdrop.length) {
				self.$backdrop = backdrop.appendTo('body');
			}

			self.settings = settings = $
					.extend({}, self.defaults, self.options);

			self.$target.on('click', function(e) {
				self.hide(e)
			});
			self.$el.on('click', function(e) {
				self.show(e)
			});
		},

		toggle : function(e) {
			return (this.$target.hasClass('in')) ? this.hide(e) : this.show(e);
		},

		show : function(e) {
			// e.preventDefault();
			// e.stopPropagation();
			this.$target.addClass('in');
			this.$backdrop.addClass('in');
			$('body').addClass('modal-open');
		},

		hide : function(e) {
			// e.preventDefault();
			// e.stopPropagation();

			var className = e.target.className;

			if (className == 'modal-dialog' || className == 'close') {
				this.$target.removeClass('in');
				this.$backdrop.removeClass('in');
				$('body').removeClass('modal-open');
			}
		},

		defaults : {}
	};

	$.fn.modal = function(options) {
		return this.each(function() {
			new $.modal(this, options);
		});
	};

	$(document).ready(function() {
		$('[data-toggle=modal]').modal();
	});
}(jQuery));
