Question

当我单击按钮时，我正在尝试将div导出为pdf，但是遇到无法解决的javascript函数错误，有人可以帮助我吗？

JavaScript

 <script language="javascript">
var cache_width = $('#renderPDF').width(); //Criado um cache do CSS
var a4 = [595.28, 841.89]; // Widht e Height de uma folha a4

    $("#btnPrint").live("click", function () {
        // Setar o width da div no formato a4
        $("#renderPDF").width((a4[0] * 1.33333) - 80).css('max-width', 'none');

        // Aqui ele cria a imagem e cria o pdf
        html2canvas($('#renderPDF'), {
            onrendered: function (canvas) {
                var img = canvas.toDataURL("image/png", 1.0);
                var doc = new jsPDF({ unit: 'px', format: 'a4' });
                doc.addImage(img, 'JPEG', 20, 20);
                doc.save('NOME-DO-PDF.pdf');
                //Retorna ao CSS normal
                $('#renderPDF').width(cache_width);
            }
        });
    });            
</script>

HTML

<div class="table-responsive panel" id="renderPDF">
  <table class="table">
    <tbody>
      <tr>
        <td class="text-success"><i class="fa fa-list-ol"></i> Cliente ID</td>
        <td>@Model.ID_Cliente</td>
      </tr>
      <tr>
        <td class="text-success"><i class="fa fa-user"></i> Nome</td>
        <td>@Model.Nome</td>
      </tr>
      <tr>
        <td class="text-success"><i class="fa fa-home"></i> Morada</td>
        <td>@Model.Morada</td>
      </tr>
    </tbody>
  </table>
</div>

@IBAction func circleRadiusChanged(_ sender: UISlider) { // Clear previous circle and create new one with updated radius mapView.removeOverlays(mapView.overlays) self.radius = circleSlider.value drawCircle() radiusTextView.text = "\(Int(radius)) KM" } func drawCircle() { let circleRadius = CLLocationDistance(self.radius * 1000) let circleRadiusx2 = CLLocationDistance(self.radius * 1000 * 2 + 300) let circle = MKCircle(center: circleCenter!, radius: circleRadius) mapView.add(circle) // Set the correct zoom based on circle radius let region = MKCoordinateRegionMakeWithDistance(circleCenter!, circleRadiusx2, circleRadiusx2); mapView.setRegion(region, animated: true) }方法已过时，可能已在您的jQuery版本中删除。

尝试改用live。

您正在使用哪个版本的jquery？ .live已从病房的1.9版中删除。

$(document).on("click", '#btnPrint', function () {
        // Setar o width da div no formato a4
        $("#renderPDF").width((a4[0] * 1.33333) - 80).css('max-width', 'none');

        // Aqui ele cria a imagem e cria o pdf
        html2canvas($('#renderPDF'), {
            onrendered: function (canvas) {
                var img = canvas.toDataURL("image/png", 1.0);
                var doc = new jsPDF({ unit: 'px', format: 'a4' });
                doc.addImage(img, 'JPEG', 20, 20);
                doc.save('NOME-DO-PDF.pdf');
                //Retorna ao CSS normal
                $('#renderPDF').width(cache_width);
            }
        });
    });
