我有一个网页,我希望打印一些HTML.
为此,我使用html2canvas和jsPDF.
我遇到的问题是它不会打印HTML中显示的图像.
我的HTML和CSS看起来如下(complete code in fiddle)：
.handsomeHtml {
background: red;
}
.crazyFrog {
background: url('http://e-cdn-images.deezer.com/images/artist/01eb92fc47bb8fb09adea9f763bb1c50/500x500.jpg');
width: 500px;
height: 500px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.js">
</script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.4/jspdf.debug.js">
</script>
<div id="someHtml" class="handsomeHtml">
Hello, handsome HTML
<br>
<img class="crazyFrog"></img>
</div>
<button id="savePDFbutton" onclick="savePDF()">
save pdf
</button>
预期结果：
实际PDF结果
解决方法:
检查此工作代码.
您也可以在fiddle上查看代码.

var doc = new jsPDF('p', 'pt', 'a4');
doc.addImage(imgData, 'PNG', 10, 10);
doc.save('sample-file.pdf');
window.open(imgData);
}
});
}
