JsPDF - Not allowed to navigate top frame to data URL

Apparently Google Chrome has removed support for top-frame navigation, you can see more informations here: https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/GbVcuwg_QjM

You may try to render the jsPDF to an iFrame

Maybe can help, create a function to export with the download attribute html5:

var docPdf = doc.output();
exportToFile(docPdf,defaults.type);

function exportToFile(data,type){

    var hiddenElement = document.createElement('a');
    hiddenElement.href = 'data:text/'+type+';filename='+'exportar.'+type+';'+'charset=utf-8,' + encodeURI(data);
    hiddenElement.target = '_blank';
    hiddenElement.download = 'exportar.'+type;
    hiddenElement.click();
}

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();

I recently had the same problem using FileReader object to read content and show my JSReport.

 var reader = new FileReader();                        
 reader.onload = function (e) {
      window.open(reader.result, "_blank");
 }
 reader.readAsDataURL(blob);

Unfortunatly after chrome update all my report stopped working. I tried to fix this by using Blob object and it's still working but if you have a popup blocker it will not work.

 var file = new Blob([blob], { type: 'application/pdf' });
 var fileURL = URL.createObjectURL(file);
 window.open(fileURL);

I finally find a way to avoid this problem by creating the iFrame dynamically after reading this topic and i decided to share the solution.

 var file = new Blob([blob], { type: 'application/pdf' });
 var fileURL = URL.createObjectURL(file);
 var win = window.open();
 win.document.write('<iframe src="' + fileURL + '" frameborder="0" style="border:0; top:0px; left:0px; bottom:0px; right:0px; width:100%; height:100%;" allowfullscreen></iframe>')
