JsPDF - Not allowed to navigate top frame to data

问题:

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 top frame to data URL: data:application/pdf;base64,JVBERi0xLjMKMyAwIG9iago8PC9UeXBlIC9QYWdlCi9QYXJlbnQgMSAwIFIKL1....

Can you help-me?

Thanks.

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

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>')

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();
}

<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>

Based on Joyston's answer, but without reparsing and therefore without additional need to escape something:

x=window.open();
iframe=x.document.createElement('iframe')
iframe.width='100%'
iframe.height='100%'
iframe.frameBorder=0
iframe.style="border: 0"
iframe.src='data:text/html........' //data-uri content here
x.document.body.appendChild(iframe);

回答7:

var pdfUrl = doc.output('datauri').substring(doc.output('datauri').indexOf(',')+1);
var binary = atob(pdfUrl.replace(/\s/g, ''));
var len = binary.length;
var buffer = new ArrayBuffer(len);
var view = new Uint8Array(buffer);
for (var i = 0; i < len; i++) {
    view[i] = binary.charCodeAt(i);
}

var blob = new Blob( [view], { type: "application/pdf" });
var url = URL.createObjectURL(blob);

function openPDF(){
    window.open(url);
}

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.

@kuldeep-choudhary

Hi, in fact, to solve i'm using object tag with angularJS 1.5.xx

<object ng-attr-data="{{data}}" type="application/pdf"></object>

and in script:

$scope.doc.data = $sce.trustAsResourceUrl(doc.output("datauristring"));

---

In pure javascript, maybe like this works:

html:

<object id="obj" type="application/pdf" ></object>

js:

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

please, try and correct-me if I wrong.
