                        <script>
                            document.getElementById('downloadBtn').addEventListener('click', function(event) {
                                event.preventDefault();
                                // 自定义逻辑 例如：发送AJAX请求或显示下载提示
                                const key_words = $('input[name="key_words"]').val();
                                const end_time = $('input[name="end_time"]').val();
                                const begin_time = $('input[name="begin_time"]').val();

                                // 获取可能需要传递的参数
                                const params = {
