javascript - 使用 jsPDF 时单选按钮不可见

Question

您好，我想生成特定div的PDF文件。为此，我发现 jsPDF 可能很有用。我是 jsPDF 和 bz 的新手，我在谷歌搜索中找到了适合我的代码行。 jsPDF 代码会将 div 转换为图像，然后将其另存为 pdf。 Mz 的问题是我在该 div 中有一个单选按钮，但是当我将 div 转换为 PDF 时，该页面的设计将与下图类似。

我不知道确切的问题是什么。这是我编写的代码。

                var imgData = canvas.toDataURL('image/png');

                /*
                Here are the numbers (paper width and height) that I found to work. 
                It still creates a little overlap part between the pages, but good enough for me.
                if you can find an official number from jsPDF, use them.
                */
                var imgWidth = 210;
                var pageHeight = 295;
                var imgHeight = canvas.height * imgWidth / canvas.width;
                var heightLeft = imgHeight;

                var doc = new jsPDF('p', 'mm');
                var position = 0;

                doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
                heightLeft -= pageHeight;

                while (heightLeft >= 0) {
                    position = heightLeft - imgHeight;
                    doc.addPage();
                    doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
                    heightLeft -= pageHeight;
                }
                doc.save('file.pdf');

尝试更改 jspdf 和 canvas javascript 链接。我用它修复了它
