使用JsPDF将Canvas转换为Pdf

Question

我试图将canvas转换为pdf但是我得到了干净的白色pdf结果这是代码,我无法弄清楚我错过了什么..

function HtmlToImage(){
    html2canvas(document.body, {
    onrendered: function(canvas) {
    var img =canvas.toDataURL("image/jpeg,1.0");  
    var pdf = new jsPDF();
    pdf.addImage(img, 'JPEG', 0, 0);
    pdf.output('datauri');
                }
          });
       }

Answer 1

试试这个:

var pdf = new jsPDF('p','pt','a4');

pdf.addHTML(document.body,function() {
    pdf.output('datauri');
});
