javascript - generate - pdfmake angular
Genere PDF desde HTML usando pdfMake en Angularjs (3)
De acuerdo, me di cuenta de esto. 1. Necesitará html2canvas y pdfmake . NO necesita hacer ninguna inyección en su app.js para nada, solo incluir en sus etiquetas de script
-
En el div del que desea crear el PDF, agregue un nombre de ID como se muestra a continuación:
<div id="exportthis"> -
En su controlador Angular, use la identificación del div en su llamada a html2canvas:
-
cambiar el lienzo a una imagen usando toDataURL ()
-
Luego, en su docDefinition for pdfmake, asigne la imagen al contenido.
-
El código completado en su controlador se verá así:
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"); } });
Espero que esto ayude a alguien más. ¡Feliz codificación!
Estoy tratando de crear un
PDF
desde mi HTML usando
pdfMake
y
Angular
(también probé
jsPDF
y tampoco pude hacerlo funcionar).
Intenté usar el siguiente código en mi controlador Angular:
var blob = new Blob([document.getElementById(''exportable'').innerHTML])
var docDefinition = {
content: [blob]
}
pdfMake.createPdf(docDefinition).open();
pero recibo el siguiente error:
Estructura de documento no reconocida: {"_margin": null} ".
Mi HTML consta de dos tablas simples en un div
exportable
.
Si alguien conoce una solución a este problema, u otra forma de obtener el HTML en un PDF desde Angular, POR FAVOR ayude.
¡Cualquier ayuda es muy apreciada!
Sé que no es relevante para esta publicación, pero podría ayudar a otros a convertir HTML a PDF en el lado del cliente. Esta es una solución simple si usa kendo. También conserva el CSS (la mayoría de los casos).
var generatePDF = function() {
kendo.drawing.drawDOM($("#formConfirmation")).then(function(group) {
kendo.drawing.pdf.saveAs(group, "Converted PDF.pdf");
});
}

esto es lo que funcionó para mí, estoy usando html2pdf desde una aplicación Angular2, así que hice una referencia a esta función en el controlador
var html2pdf = (function(html2canvas, jsPDF) {
declarado en html2pdf.js.
Entonces agregué justo después de las declaraciones de importación en mi controlador angular esta declaración:
declare function html2pdf(html2canvas, jsPDF): any;
entonces, desde un método de mi controlador angular, llamo a esta función:
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'' }
});
}
);
}
Espero eso ayude
