I am currently working on a school management software that usually requires exporting of html contents that contains data tables
and div tag
.
我已经尝试了所有可能的方法来编写一个代码,以便能够以良好的方式导出我的html数据,最好使用css。在检查一些问题和答案在这里,我尝试使用spdf,但没有运气。
I have tried all possible means to write a code that will be able to export my html data in a good way, with css preferably. After checking some question and answers here, I tried using spdf, but no luck.
它保持破坏我的表对齐,然后我阅读关于 html2canvas
,但实现它与 jspdf
是我的问题,我想捕获的内容,如果一个div标签与 html2canvas
然后发送画布到 jspdf
将画布导出为pdf。
It keeps destroying my table alignment, then I read about html2canvas
but to implement it with jspdf
was my problem, i would like to capture the content if a div tag with html2canvas
then send the canvas to jspdf
to export the canvas as pdf.
以下是我的代码:
<script src="assets/js/pdfconvert/jspdf.js"></script>
<script src="assets/js/pdfconvert/jspdf.plugin.from_html.js"></script>
<script src="assets/js/pdfconvert/jspdf.plugin.split_text_to_size.js"></script>
<script src="assets/js/pdfconvert/jspdf.plugin.standard_fonts_metrics.js"> </script>
<script src="assets/js/pdfconvert/jspdf.plugin.addhtml.js"></script>
<script src="assets/js/pdfconvert/filesaver.js"></script>
<script src="assets/js/pdfconvert/jspdf.plugin.cell.js"></script>
<script src="assets/js/pdfconvert/html2canvas.js"></script>
<script src="assets/js/pdfconvert/jspdf.plugin.addimage.js"></script>
这里是js代码
var pdf = new jsPDF('p', 'pt', 'letter');
pdf.addHTML($('#ElementYouWantToConvertToPdf')[0], function () {
pdf.save('Test.pdf');
});
推荐答案
我为你做了一个jsfiddle。
I have made a jsfiddle for you.
<canvas id="canvas" width="480" height="320"></canvas>
<button id="download">Download Pdf</button>
'
html2canvas($("#canvas"), {
onrendered: function(canvas) {
var imgData = canvas.toDataURL(
'image/png');
var doc = new jsPDF('p', 'mm');
doc.addImage(imgData, 'PNG', 10, 10);
doc.save('sample-file.pdf');
}
});

在Chrome38,IE11和Firefox 33测试。似乎Safari有问题。但是,Andrew通过从PNG切换到JPEG,在Mac OSx的Safari 8中工作。有关详情,请参阅以下他的评论。
