How do I display all pages in a PDF (stored in base64) using PDF.js?

I am using the following script to display a PDF using PDF.js, but it does not show anything on the canvas. Can you tell me where I am going wrong with this? I tried looking for documentation online, but could not find any help.

@Model.B is the base64 string.

<script>

        var pdfData = atob("@Model.B");

        var pdfjsLib = window['pdfjs-dist/build/pdf'];

        pdfjsLib.GlobalWorkerOptions.workerSrc = '//mozilla.github.io/pdf.js/build/pdf.worker.js';

        var loadingTask = pdfjsLib.getDocument({ data: pdfData });

        loadingTask.getDocument(pdfData).promise.then(function (pdf) {

            thePdf = pdf;

            viewer = document.getElementById('pdfData');

            for (page = 1; page <= pdf.numPages; page++) {

                canvas = document.createElement("canvas");

                canvas.className = 'pdf-page-canvas';

                viewer.appendChild(canvas);

                renderPage(page, canvas);

            }

        });

        function renderPage(pageNumber, canvas) {

            thePdf.getPage(pageNumber).then(function (page) {

                viewport = page.getViewport(scale);

                canvas.height = viewport.height;

                canvas.width = viewport.width;

                page.render({ canvasContext: canvas.getContext('2d'), viewport: viewport });

            });

    }

</script>

The following is the div. I used the embed tag to see if the PDF data was correct or not.

<div class="form-inline" style="margin-left:130px; margin-top:20px; display:none" id="pdfData" role="group" aria-label="Basic example">

    <embed src="data:application/pdf;base64,@Model.B" style="height: 750px; width: 1000px;" alt="pdf" type="application/pdf"/>

     @ViewBag.Error

        <div class="form-group row" style="margin-top: 20px; margin-left: 25px">

         Accept Policy

             <div class="col-sm-6 col-sm-offset-2 col-xs-6 col-xs-offset-0" , style="text-align:justify; margin-top: 20px;">

                 @Html.CheckBoxFor(model => model.C)

                 @Html.ValidationMessageFor(model => model.C, "", new { @class = "form-text", style = "color:rgb(184, 10, 10); font-size:12px;" })

             </div>

     <div class="form-inline"  role="group" aria-label="Basic example">

           <button type="submit" class="btn btn-default btn-sm" id="submit_Agreement" name="submit_Agreement" title="Agree to Policy" onclick="">

                 Submit

           </button>

 </div>

 </div>

Any errors (on development console)? Can you inspect the page and determine if canvas elements are actually created?

Oct 29 '18 at 12:07

No, the canvas elements are not created. Also, when I debug it, the code never goes to the var pdfjsLib declaration line in the script.

Oct 29 '18 at 12:10

Seems like the first line of code is throwing an error. By the way - are you sure you are not missing a razor block? JS does not now what the value behind @Model.B

I tried the same code earlier without the for loop to display the first page, and it worked perfectly fine. I was referring to the example shown here: mozilla.github.io/pdf.js/examples

– Jitesh G

I think it is better for you do replace the loop with a console.log(pdf) statement, inspect the values from your debugger / dev console and proceed from there
