尝试使用jsPdf从html创建pdf时出错

Question

当我尝试使用jsPdf从html创建pdf时出错。我的代码有什么问题吗？ 提前谢谢

错误

ng:///AppModule/TemplateComponent.ngfactory.js:198 ERROR TypeError: Cannot read property 'name' of undefined

component.ts

只有当我点击按钮将html导出为pdf时才会抛出错误。

import * as jsPDF from 'jspdf';

@Component({
  selector: 'app-template',
  templateUrl: './template.component.html',
  styleUrls: ['./template.component.scss']
})
export class TemplateComponent implements OnInit {

  constructor() {

  }


  ExportToPdf() {
    let doc = new jsPDF();
    let specialElementHandlers = {
      '#editor': function (element, renderer) {
        return true;
      }
    };
    let content = this.content.nativeElement;
    doc.fromHTML(content.innerHTML, 15, 15, {
      'width': 190,
      'elementHandlers': specialElementHandlers
    });

    doc.save('report.pdf');
  }



  ngOnInit() {
    this.getLocalData();

  }

}
