 <div class="modal fade" id="myModalLarge" tabindex="-1" role="dialog" aria-labelledby="myModalLabelLarge" aria-hidden="true">
<div class="modal-dialog modal-lg">

        <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>
                    <button class="btn btn-primary" type="button" id="toPdf">Export To Pdf</button>
                </div>
            </div>
        </div>
    </div>
</div>

这是js代码

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');
        });
    });

除了页脚和页眉，我正在导出整个模式。我的情态就是这样

但是当我将其导出为pdf时，它会像这样导出

我正在使用jspdf。我给整个模态内容指定一个id，该id传入jspdf对象以创建pdf，但是当我导出时，它切掉了上面的3个蓝色小部件。

尝试使用.Suffix()代替.html()。要忽略div，请使用.addHtml()。

data-html2canvas-ignore="true"
