my code as below:
Template.mpdfviewer.rendered=function(){
//loaded();
var v_content=Session.get(“PDF”);
swal("render start ");
PDFJS.workerSrc = “/packages/pascoual_pdfjs/build/pdf.worker.js”;
swal("render worksrc over "+v_content.num);
PDFJS.getDocument(v_content.content).then(function (pdf) {
swal("render start 0 ");
// Fetch the first page
//document.getElementById(‘page_count’).textContent = pdf.numPages;
pdf.getPage(1).then(function(page) {
var scale = 1;
swal("render start 1 ");
var viewport = page.getViewport(scale);
// Prepare canvas using PDF page dimensions
var canvas = document.getElementById(‘pdfcanvas’);
var context = canvas.getContext(‘2d’);
canvas.height = viewport.height;
canvas.width = viewport.width;
var pdffile={num:1,content:v_content.content};
//document.getElementById(‘page_num’).textContent = 1;
Session.set(“PDF”,{});
Session.set(“PDF”,pdffile);
swal("render start 2 ");
// Render PDF page into canvas context
page.render({canvasContext: context, viewport: viewport});
swal("render start 3 ");
});
