        <div class="row">
            <div class="col-md-12">
                <div class="modal-footer" id="ignore1">
                    <button class="btn btn-secondary" type="button" data-dismiss="modal" style="margin-left:40px">Close</button>

                </div>
            </div>
        </div>
    </div>
</div>

Вот код JS

var doc = new jsPDF('p', 'pt', 'a4');
    var elementHandler = {
        '#ignore1': function (element, renderer) {
            return true;
        }
    };
    $('#toPdf').click(function () {
        doc.addHTML($('#content'), {
            'elementHandlers': elementHandler
        }, function () {
            doc.save('sample-file.pdf');
        });
    });

Я экспортирую весь модальный текст, кроме нижнего колонтитула и заголовка. Мой модал такой

Но когда я экспортирую его в формате PDF, он экспортируется вот так

Я использую jspdf. Я даю всему модальному содержимому идентификатор, который передается в объект jspdf для создания pdf, но когда я экспортирую, он разрезает верхние 3 синих виджета.

Попробуйте использовать .html() вместо .addHtml(). Чтобы игнорировать div, используйте data-html2canvas-ignore="true".
