Generovat PDF z HTML pomocí pdfMake v Angularjs

Snažím se vytvořit PDF z mého HTML pomocí pdfMake a Angular (také jsem se snažil jsPDF a nemohl jsem to dostat do práce). V kontroleru Angular jsem použil následující kód:

var blob = new Blob([document.getElementById('exportable').innerHTML])
var docDefinition = {
    content: [blob]
}
pdfMake.createPdf(docDefinition).open();

ale obdržím následující chybu: 

Nezjištěná struktura dokumentu: {"_margin": null} ".

Moje HTML se skládá ze dvou jednoduchých tabulek v div exportable.

Pokud někdo ví řešení tohoto problému, nebo jiný způsob, jak dostat HTML do PDF z Angular, PLEASE help.

Jakákoli pomoc je VELKÁ oceňována!

Dobře, přišel jsem na to. 1. Budete potřebovat html2canvas a pdfmake . Nemusíte dělat žádné injekce v app.js buď, stačí zahrnout do skriptu tagy

  1. Na stránce div, kterou chcete vytvořit PDF, přidejte název ID, jako je následující:

     <div id="exportthis">
    
  2. Ve vašem řadiči Angular použijte ID div ve vašem volání na html2canvas:

  3. změnit plátno na obrázek pomocí příkazu toDataURL ()

  4. Pak ve vašem docDefinition pro pdfmake přiřaďte obrázek k obsahu.

  5. Vyplněný kód ve vašem řadiči bude vypadat takto:

           html2canvas(document.getElementById('exportthis'), {
                onrendered: function (canvas) {
                    var data = canvas.toDataURL();
                    var docDefinition = {
                        content: [{
                            image: data,
                            width: 500,
                        }]
                    };
                    pdfMake.createPdf(docDefinition).download("Score_Details.pdf");
                }
            });
    

Doufám, že to pomůže někomu jinému. Šťastné kódování!

Vím, že není relevantní pro tento post, ale může pomoci ostatním převést HTML na PDF na straně klienta. Toto je jednoduché řešení, pokud používáte kendo. To také zachovává css (většina případů).

var generatePDF = function() {
  kendo.drawing.drawDOM($("#formConfirmation")).then(function(group) {
    kendo.drawing.pdf.saveAs(group, "Converted PDF.pdf");
  });
}

Mahib

to je to, co to pro mě pracovalo Používám html2pdf z aplikace Angular2, takže jsem udělal odkaz na tuto funkci v řadiči

var html2pdf = (function(html2canvas, jsPDF) {

deklarováno v html2pdf.js.

Tak jsem přidal těsně po dovozních prohlášeních do svého úhlového regulátoru toto prohlášení:

declare function html2pdf(html2canvas, jsPDF): any;

pak, z metody mého úhlového regulátoru, volám tuto funkci:

generate_pdf(){
    this.someService.loadContent().subscribe(
      pdfContent => {
        html2pdf(pdfContent, {
          margin:       1,
          filename:     'myfile.pdf',
          image:        { type: 'jpeg', quality: 0.98 },
          html2canvas:  { dpi: 192, letterRendering: true },
          jsPDF:        { unit: 'in', format: 'A4', orientation: 'portrait' }
        });
      }
    );
  }

Doufám, že to pomůže
