javascript - how to display base64 encoded pdf?

asked Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

I have to display base64 pdf in new tab. I am using below code

 var windo = window.open("", "");  
 var objbuilder = '';
 objbuilder += ('<embed width='100%' height='100%'  src="data:application/pdf;base64,');
 objbuilder += (fileData);
 objbuilder += ('" type="application/pdf" />');
 windo.document.write(objbuilder);

It is working in FireFox and not working in Chrome and IE. I even tried with tag, but same output, working in FF but not in Chrome and IE.

I look into below JsFiddles, for which are working in FF but not in Chrome,

My Chrome version is : Version 54.0.2840.99 m

FireFox Version : 49.0.2

Is any one have any idea, please share.

Thanks in Advance

for those who still can't do it, i found this in someone else answer, but i don't remember who...

var objbuilder = '';
objbuilder += ('<object width="100%" height="100%" 
data="data:application/pdf;base64,');
objbuilder += (myBase64string);
objbuilder += ('" type="application/pdf" class="internal">');
objbuilder += ('<embed src="data:application/pdf;base64,');
objbuilder += (myBase64string);
objbuilder += ('" type="application/pdf"  />');
objbuilder += ('</object>');

var win = window.open("#","_blank");
var title = "my tab title";
win.document.write('<html><title>'+ title +'</title><body style="margin-top: 
0px; margin-left: 0px; margin-right: 0px; margin-bottom: 0px;">');
win.document.write(objbuilder);
win.document.write('</body></html>');
layer = jQuery(win.document);

this way we open the pdf in a new tab.
