我正在尝试使用pdfmake生成带水印的pdf。但是，在使用属性“watermark:“test”时，没有生成pdf。控制台上弹出一个错误，说“在文档定义的字体部分中没有定义样式“normal”中的字体“undefined”。如何使用pdfmake JS库生成带水印的pdf。

<script src='https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.20/vfs_fonts.js'></script>
<script type="text/javascript">
function myFunction()
{
var docDefinition = {
watermark:'test',
background: 'simple text',
content: 'This is an sample PDF printed with pdfMake'
};
pdfMake.createPdf(docDefinition).download('Report.pdf');
}
</script>

<body>
<button type="button" onclick="myFunction()">Click Me!</button>

最佳答案
这个问题在更新版本的pdfMake中解决了，请确保使用最新版本，它将正常工作。
function myFunction() {
var docDefinition = {
watermark: 'test',
background: 'simple text',
content: 'This is an sample PDF printed with pdfMake'
};
pdfMake.createPdf(docDefinition).download('Report.pdf');
}<script src='https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.31/pdfmake.min.js'></script>
<script src='https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.31/vfs_fonts.js'></script>
<button type="button" onclick="myFunction()">Click Me!</button>
