Exporting PDF with jspdf not rendering CSS

2019-01-06 17:40发布

问题:

I am using jspdf.debug.js to export different data from a website but there are a few problems, I can't get it to render the CSS in the exported PDF and if I have an image in the page I am exporting, the PDF returns blank...

Does anyone know a way to fix this ?

Here is a jsfiddle showing it's not rendering the CSS

And my script

$(document).ready(function() {
$('#export').click(function(){
var d = new Date().toISOString().slice(0, 19).replace(/-/g, ""),
        filename = 'financiar_' + d + '.pdf',
        pdf = new jsPDF('p', 'pt', 'letter'),
        specialElementHandlers = {
          '#editor': function( element, renderer ) {
              return true;
          }
    };
    pdf.fromHTML(
          $('.export').get(0) // HTML element
        , 25  // x coord
        , 25  // y coord
        , {
              'width': 550 // was 7.5, max width of content on PDF
            , elementHandlers: specialElementHandlers
        }
    );
    pdf.save( filename );
})
});

As I know jsPDF is not working with CSS and the same issue I was facing.

To solve this issue , i used Html2Canvas So just Add HTML2Canvas JS and then use pdf.addHTML() instead of pdf.fromHTML().

Here's my code (no other code):

 var pdf = new jsPDF('p', 'pt', 'letter');
 pdf.addHTML($('#ElementYouWantToConvertToPdf')[0], function () {
     pdf.save('Test.pdf');
 });

Best of Luck!

Edit: Refer here in case you didn't find addHTML()

jspdf does not work with css but it can work along with html2canvas. You can use jspdf along with html2canvas.

include these two files in script on your page :

<script type="text/javascript" src="html2canvas.js"></script>
  <script type="text/javascript" src="jspdf.min.js"></script>
  <script type="text/javascript">
  function genPDF()
  {
   html2canvas(document.body,{
   onrendered:function(canvas){

   var img=canvas.toDataURL("image/png");
   var doc = new jsPDF();
   doc.addImage(img,'JPEG',20,20);
   doc.save('test.pdf');
   }

   });

  }
  </script>

You need to download script files such as https://github.com/niklasvh/html2canvas/releases https://cdnjs.com/libraries/jspdf

make clickable button on page so that it will generate pdf and it will be seen same as that of original html page.

<a href="javascript:genPDF()">Download PDF</a>  

It will work perfectly.

You can get the example of css implemented html to pdf conversion using jspdf on following link: JSFiddle Link

This is sample code for the jspdf html to pdf download.

$('#print-btn').click(() => {
    var pdf = new jsPDF('p','pt','a4');
    pdf.addHTML(document.body,function() {
        pdf.save('web.pdf');
    });
})
