Converting Div into PDF INCLUDING images
提问by Deedub
am referencing this post Download a div in a HTML page as pdf using javascript
我正在引用这篇文章 Download a div in a HTML page as pdf using javascript
which basically uses jspdf to make a div into a pdf. I got it to work, but the only problem is I can't get it to add an image as well that would be contained in the div. In other words, I can get the text that's in the div to be a pdf but not the image inside.
它基本上使用 jspdf 将 div 转换为 pdf。我让它工作了，但唯一的问题是我无法让它添加一个包含在 div 中的图像。换句话说，我可以让 div 中的文本成为 pdf 而不是里面的图像。

One solution is to use the html2canvasor rasterizeHTMLlibrary. They create a canvas of the HTML page which you can then add to the PDF using addHTML
一种解决方案是使用html2canvasorrasterizeHTML库。他们创建 HTML 页面的画布，然后您可以使用它添加到 PDFaddHTML
$('#cmd').click(function() {
var options = {};
var pdf = new jsPDF('p', 'pt', 'a4');
pdf.addHTML($("#content"), 15, 15, options, function() {
pdf.save('pageContent.pdf');
});
});

This code may help(It worked for me):
此代码可能有帮助（它对我有用）：
<script type="text/javascript">
$(document).ready(function () {
setTimeout(function(){
downloadImage();
},1000)
});
function downloadImage(){
html2canvas(document.querySelector("#divID")).then(canvas => {
a = document.createElement('a');
document.body.appendChild(a);
a.download = "test.png";
a.href = canvas.toDataURL();
a.click();
});
}
</script>
