如何从magento 2中的ajax帖子获取数据

Question

我尝试将数据插入到由ajax发布为json数据的数据库中。

这是我的HTML：

<form action="" id="crmore_checkout_betting_form">
    <input type="checkbox" name="bet[betting_id]" id="bettingID_1" value="1">
    <input type="checkbox" name="bet[betting_id]" id="bettingID_2" value="2">
    <input type="checkbox" name="bet[betting_id]" id="bettingID_3" value="3">
</form>

这是我的ajax，我使用ajax从上面的表单中发布数据：

<script>
    require(
        [
            'jquery',
            'Magento_Ui/js/modal/modal'
        ],
        function(
            $,
            modal
        ) {
            var options = {
                type: 'popup',
                responsive: true,
                innerScroll: true,
                title: 'Bet list',
                buttons: [{
                    text: $.mage.__('Place Bet'),
                    class: '',
                    click: function () {
                        //this.closeModal();
                        var values = '';
                        values = $('#crmore_checkout_betting_form').serialize();

                        $.ajax({
                            showLoader: true,
                            url: "../../betting/placebet/place",
                            data: values,
                            type: "POST",
                            dataType: 'json'
                        }).done(function (data) {
                            alert(data);
                        });
                    }
                }]
            };

            var popup = modal(options, $('#betting_form_popup'));
            $(document).ready(function(){
                $('#betting_place_button').click(function(){
                    $('#betting_form_popup').modal('openModal');
                });
            });
        }
    );
</script>

这是我想要从ajax接收数据的控制器： 我在这里使用JsonFactory，但我不知道它是对的。

<?php
    namespace Crmore\Betting\Controller\Placebet;
    use Magento\Framework\App\Action\Context;

    class Place extends \Magento\Framework\App\Action\Action{
        protected $jsonResultFactory;

        public function __construct(
            \Magento\Framework\App\Action\Context $context,
            \Magento\Framework\Controller\Result\JsonFactory $jsonResultFactory
        ) {
            parent::__construct($context);
            $this->jsonResultFactory = $jsonResultFactory;
        }

        public function execute()
        {
            /** @var \Magento\Framework\Controller\Result\Json $result */
            $result = $this->jsonResultFactory->create();

            // here is where I want to write the code to simply display data posted by ajax but I don't know how.

            $result->setData(['msg' => __('Bet Placed')]);
            return $result;
        }
    }

请帮忙。
