reactjs - jsPDF , TypeError : pdf. fromHTML 不是 REACT 中的函数

Question

我正在使用下一个代码使用 jsPDF 和一个简单的 react 组件将 HTML 转换为 PDF。

import React from 'react';
import { renderToString } from 'react-dom/server';

import jsPDF from 'jspdf';

const styles = {
    fontFamily: 'sans-serif',
    textAlign: 'center',
};
const colstyle = {
    width: '30%',
};
const tableStyle = {
    width: '100%',
};

const Prints = () => (
    <div>
        <h3>Time & Materials Statement of Work (SOW)</h3>
        <h4>General Information</h4>
        <table id='tab_customers' class='table table-striped' style={tableStyle}>
            <colgroup>
                <col span='1' style={colstyle} />
                <col span='1' style={colstyle} />
            </colgroup>
            <thead>
                <tr class='warning'>
                    <th>SOW Creation Date</th>
                    <th>SOW Start Date</th>
                    <th>Project</th>
                    <th>Last Updated</th>
                    <th>SOW End Date</th>
                </tr>
            </thead>
            <tbody>
                <tr>
                    <td>Dec 13, 2017</td>
                    <td>Jan 1, 2018</td>
                    <td>NM Connect - NMETNMCM</td>
                    <td>Dec 13, 2017</td>
                    <td>Dec 31, 2018</td>
                </tr>
            </tbody>
        </table>
        <p>
            This is a Time and Materials Statement of Work between Northwestern Mutual Life
            Insurance Company and Infosys with all general terms and conditions as described
            in the current Master Agreement and its related documents
        </p>
    </div>
);

const print = () => {
    const string = renderToString(<Prints />);
    const pdf = new jsPDF('p', 'mm', 'a4');

    console.log(typeof pdf);
    pdf.fromHTML(string);
    pdf.save('pdf');
};

const Prescription = () => {
    return (
        <div>
            <h1>RECETA</h1>
            <div style={styles}>
                <h2>Start editing to see some magic happen {'\u2728'}</h2>
                <button onClick={print}>print</button>
            </div>
        </div>
    );
};

export default Prescription;

错误是:

TypeError: pdf.fromHTML is not a function

我该如何修复错误？
我试图寻找“Typeof”并显示“Object”。
我想在客户端将 REACT 组件中的 HTML 转换为可下载的 PDF。

你的实现是完全正确的。发生此问题的原因是 jspdf版本。不要使用最新版本，而是使用 V1.4.1 (见附件截图)。
