使用 jsPDF 无法正确显示单选按钮

Radiobutton is not visible properly using jsPDF

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 谷歌搜索的新手,我发现了一些适合我的代码行。 jsPDF 代码会将 div 转换为图像,然后将其另存为 pdf。 Mz 问题是我在 div 中有一个单选按钮,但是当我将 div 转换为 PDF 时,该页面的设计将类似于下面的图像..

我不知道确切的问题是什么。这是我写的代码。

                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 javscript link。 我用它修复了它
