如何在新窗口中使用jspdf打开生成的pdf

Question

I am using jspdf to generate a pdf file. Every thing is working fine. But how to open generated pdf in new tab or new window.

I am using

doc.output('datauri');

Which is opening the pdf in same tab.

Answer 1

Based on the source you can use the 'dataurlnewwindow' parameter for output():

doc.output('dataurlnewwindow');

Source in github: https://github.com/MrRio/jsPDF/blob/master/jspdf.js#L914

All possible cases:

doc.output('save', 'filename.pdf'); //Try to save PDF as a file (not works on ie before 10, and some mobile devices)
doc.output('datauristring');        //returns the data uri string
doc.output('datauri');              //opens the data uri in current window
doc.output('dataurlnewwindow');     //opens the data uri in new window

Answer 2

I have to use this to load the PDF directly. Using doc.output('dataurlnewwindow'); produces an ugly iframe for me. Mac/Chrome.

  var string = doc.output('datauristring');
  var x = window.open();
  x.document.open();
  x.document.location=string;

Answer 3

这个解决方案对我有用

window.open(doc.output('bloburl'))

Answer 4

Or... You can use Blob to achive this.

Like:

pdf.addHTML($('#content'), y, x, options, function () {
    var blob = pdf.output("blob");
    window.open(URL.createObjectURL(blob));
});

That code let you create a Blob object inside the browser and show it in the new tab.

Answer 5

1. Search in jspdf.js this:

    if(type == 'datauri') { document.location.href ='data:application/pdf;base64,' + Base64.encode(buffer); }

2. Add :

    if(type == 'datauriNew') { window.open('data:application/pdf;base64,' + Base64.encode(buffer)); }

3. call this option 'datauriNew' Saludos ;)

Answer 6

using javascript you can send the generated pdf to a new window using the following code.

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 7

我就是这样处理的。

window.open(doc.output('bloburl'), '_blank');

Answer 8

this code will help you to open generated pdf in new tab with required title

 let pdf = new jsPDF();
 pdf.setProperties({
          title: "Report"
      });
      pdf.output('dataurlnewwindow');

Answer 9

Javascript code

// IE doesn't allow using a blob object directly as link href
// instead it is necessary to use msSaveOrOpenBlob
if (window.navigator && window.navigator.msSaveOrOpenBlob) {
  window.navigator.msSaveOrOpenBlob(doc.output("blob"), "Name.pdf");
} else {

  // For other browsers:
  // Create a link pointing to the ObjectURL containing the blob.
  doc.autoPrint();
  window.open(
    URL.createObjectURL(doc.output("blob")),
    "_blank",
    "height=650,width=500,scrollbars=yes,location=yes"
  );

  // For Firefox it is necessary to delay revoking the ObjectURL
  setTimeout(() => {    
    window.URL.revokeObjectURL(doc.output("bloburl"));
  }, 100);
}

Answer 10

This works for me!!!

When you specify window features, it will open in a new window

Just like :

window.open(url,"_blank","top=100,left=200,width=1000,height=500");

Answer 11

Step I: include the file and plugin

../jspdf.plugin.addimage.js

Step II: build PDF content var doc = new jsPDF();

doc.setFontSize(12);
doc.text(35, 25, "Welcome to JsPDF");
doc.addImage(imgData, 'JPEG', 15, 40, 386, 386);

Step III: display image in new window

doc.output('dataurlnewwindow');

Stepv IV: save data

var output = doc.output();
return btoa( output);

Answer 12

STEP 1
Turn off addblock

STEP 2
Add

window.open(doc.output('bloburl'), '_blank');

Or try

doc.output('dataurlnewwindow')

Answer 13

Generally you can download it, show, or get a blob string :

const pdfActions = {
    save: () => doc.save(filename),
    getBlob: () => {
      const blob = doc.output('datauristring');
      console.log(blob)
      return blob
    },
    show: () => doc.output('dataurlnewwindow')
  }

Answer 14

Javascript code: Add in end line

$("#pdf_preview").attr("src", pdf.output('datauristring'));

HTML Code: Insert in body

<head>
</head>
<body>
<H1>Testing</h1>
<iframe id="pdf_preview" type="application/pdf" src="" width="800" height="400"></iframe>
</body>
</html>

preview within same window inside iframe along with with other contents.

Answer 15

Additionally, it is important to remember that the output method has other values and it might be interesting to test all of them to choose the ideal one for your case.

https://artskydj.github.io/jsPDF/docs/jsPDF.html#output

test one line at a time:

doc.output('arraybuffer');
doc.output('blob');
doc.output('bloburi');
doc.output('bloburl');
doc.output('datauristring');
doc.output('dataurlstring');
doc.output('datauri');
doc.output('dataurl');
doc.output('dataurlnewwindow');
doc.output('pdfobjectnewwindow');
doc.output('pdfjsnewwindow');
