在IE浏览器中打开pdf

Question

I need to open the pdf file in IE Browser. Is there any way we can achieve that.This works only in chrome

var byteCharacters = atob(response.data);
var byteNumbers = new Array(byteCharacters.length);
for (var i = 0; i < byteCharacters.length; i++) {
  byteNumbers[i] = byteCharacters.charCodeAt(i);
}
var byteArray = new Uint8Array(byteNumbers);
var file = new Blob([byteArray], { type: 'application/pdf;base64' });
var fileURL = URL.createObjectURL(file);
window.open(fileURL);

Answer 1

IE doesn't support URL.createObjectURL() . IE has its own API for creating and downloading files, which is called msSaveBlob or msSaveOrOpenBlob . The difference between the msSaveBlob and msSaveOrOpenBlob methods is that the former only provides a Save button to the user whereas the latter provides both a Save and an Open button.

Besides, IE doesn't have PDF viewer embeded, so you can't display PDFs directly in IE 11. You can only use msSaveOrOpenBlob to handle blobs in IE, then choose to open or save the PDF file:

if(window.navigator.msSaveOrOpenBlob) {
    //IE11
    window.navigator.msSaveOrOpenBlob(blobData, fileName); 
}
else{
   //Other browsers
    window.URL.createObjectURL(blobData);
    ...
}
