Создание PDF из HTML с помощью pdfMake в Angularjs
Я пытаюсь создать PDF из моего HTML с помощью pdfMake и Angular (я также пробовал jsPDF и не мог заставить его работать). Я попытался использовать следующий код в моем контроллере Angular:
var blob = new Blob([document.getElementById('exportable').innerHTML])
var docDefinition = {
content: [blob]
}
pdfMake.createPdf(docDefinition).open();
но я получаю следующую ошибку:
Нераспознанная структура документа: { "_margin": null} ".
Мой HTML состоит из двух простых таблиц в div exportable.
Если кто-нибудь знает решение этой проблемы или другой способ получить HTML в PDF из Angular, ПОЖАЛУЙСТА, помогите.
Любая помощь очень ценится!
Ответы
Ответ 1
Хорошо, я понял это.
1. Вам понадобится html2canvas и pdfmake, Вам не нужно делать какие-либо инъекции в вашем приложении app.js, просто включите в теги script
-
В div, который вы хотите создать PDF файл, добавьте идентификационное имя, как показано ниже:
<div id="exportthis">
-
В вашем контроллере Angular используйте идентификатор div в вашем вызове html2canvas:
-
измените холст на изображение, используя toDataURL()
-
Затем в вашем документе docDefinition for pdfmake назначьте изображение в контент.
-
Завершенный код в вашем контроллере будет выглядеть следующим образом:
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");
}
});
Надеюсь, это поможет кому-то другому. Счастливое кодирование!

Я знаю, что он не имеет отношения к этому сообщению, но может помочь другим конвертировать HTML в PDF на стороне клиента. Это простое решение, если вы используете кендо. Он также сохраняет css (большинство случаев).
var generatePDF = function() {
kendo.drawing.drawDOM($("#formConfirmation")).then(function(group) {
kendo.drawing.pdf.saveAs(group, "Converted PDF.pdf");
});
}

Ответ 3
это то, для чего он работал у меня
Я использую html2pdf из приложения Angular2, поэтому я сделал ссылку на эту функцию в контроллере
var html2pdf = (function(html2canvas, jsPDF) {
объявлен в html2pdf.js.
Итак, я добавил сразу после деклараций импорта в моем angular -controller это объявление:
declare function html2pdf(html2canvas, jsPDF): any;
то из метода моего контроллера angular я вызываю эту функцию:
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' }
});
}
);
}
Надеюсь, что это поможет
