In my application i am sending a path to the server and which returns me a pdf file contents in base64 string. Now i want to show this string in external viewer (viewer.html) using pdf.js. I am doing in this in following way, what wrong am i doing?
var res="JVBERi0xLjUK..."; // Base64 String from response shortened
var pdfData = base64ToUint8Array(res);
window.open('pdfJs/viewer.html?file='+pdfData);
function base64ToUint8Array(base64) {
var raw = atob(base64); //This is a native function that decodes a base64-encoded string.
var uint8Array = new Uint8Array(new ArrayBuffer(raw.length));
for(var i = 0; i < raw.length; i++) {
uint8Array[i] = raw.charCodeAt(i);
}
return uint8Array;
}
Output i am getting now:
I have gone through some of answers but cant sort it out. So please help me.

The Uint8Array cannot be passed via query string. Use PDFViewerApplication.open() method on the opened window, e.g.
var w = window.open('web/viewer.html?file=');
w.addEventListener('load', function () {
var res="JVBERi0xLjUK..."; // Base64 String from response shortened
var pdfData = base64ToUint8Array(res);
w.PDFViewerApplication.open(pdfData);
function base64ToUint8Array(base64) {
var raw = atob(base64);
var uint8Array = new Uint8Array(raw.length);
for(var i = 0; i < raw.length; i++) {
uint8Array[i] = raw.charCodeAt(i);
}
return uint8Array;
}
}, true);
