JsPDF - Not allowed to navigate top frame to data URL

Question

After updating Google Chrome, the report jsPDF in a new Window does not work any more.

The console shows the message:

Not allowed to navigate

Answer 1

In angular2+ -

app.component.html -

 <object id="obj"  [attr.data]  type="application/pdf"> </object>

app.component.ts

 document.getElementById('obj').dataset.data = doc.output("datauristring");

  var blob = doc.output("blob");
  window.open(URL.createObjectURL(blob));

Answer 2

Using download="" made me able to download the file

Answer 3

This works well now that chrome has removed top frame navigation. Only downloading the pdf in chrome gives problem. Download works in well in firefox tho.

var string = doc.output('datauristring');
var iframe = "<iframe width='100%' height='100%' src='" + string + "'></iframe>"
var x = window.open();
x.document.open();
x.document.write(iframe);
x.document.close();

Answer 4

<iframe id="ManualFrame"
        frameborder="0"
        style="border:0"
        allowfullscreen>
</iframe>

<script>
    $(function () {
        setManualFrame();
    });

    function setManualFrame() {
        $("#ManualFrame").attr("height", screen.height);
        $("#ManualFrame").attr("width", screen.width);
        $("#ManualFrame").attr("src", "data:application/pdf;base64," + Your_PDF_Data);
    }
</script>

Answer 5

/**
 * Creates an anchor element `<a></a>` with
 * the base64 pdf source and a filename with the
 * HTML5 `download` attribute then clicks on it.
 * @param  {string} pdf 
 * @return {void}     
 */
function downloadPDF(pdf) {
    const linkSource = `data:application/pdf;base64,${pdf}`;
    const downloadLink = document.createElement("a");
    const fileName = "vct_illustration.pdf";

    downloadLink.href = linkSource;
    downloadLink.download = fileName;
    downloadLink.click();
}

Answer 6

Not related to jspdf, but did help me here (and this question is the top hit at google): If specifying a download="..." attribute to the anchor tag, the download prompt will properly open up.
