我是 Angular 4 的新手。我需要下载 pdf 格式的 HTML 网页，并且 html 网页包含输入等 Angular 控件[（ng模型）]， 单选按钮[已检查]。
它显示的不是控制值不明确的在pdf文件中。
我尝试使用jsPdf 和 html2Pdf但它会抛出错误
Error:
You need either https://github.com/niklasvh/html2canvas or https://github.com/cburgmer/rasterizeHTML.js
at Object.jsPDFAPI.addHTML (jspdf.debug.js?6964:4049)
TS文件代码：
import { Component, ViewChild, Compiler, ComponentRef, OnInit, EventEmitter, ElementRef } from "@angular/core";
import { Router } from '@angular/router';
import { FormGroup, FormBuilder, FormControl, Validators } from '@angular/forms';
import * as jsPDF from 'jspdf';
import * as html2canvas from 'html2canvas';
@Component({
templateUrl: "./dashboard.html"
})
export class DashboardComponent implements OnInit {
ngOnInit() {
}
pdf() {
let pdf = new jsPDF();
let options = {
pagesplit: true
};
pdf.addHTML(document.getElementById("htmlform"), 0, 0, options, () => {
pdf.save("test.pdf");
});
}
}
