How to open Blob in Chrome on iOS

[Tomáš Masník]

I want to open Blob object from javascript and the only thing I can see is
a blank page.

*Description:*
I want to open Blob object from javascript and the only thing I can see is
a blank page. Code:

var blob = new window.Blob(['Hello, world!'], {type:
'text/plain;charset=utf-8'});
window.URL = window.URL || window.webkitURL;
var url = window.URL.createObjectURL(blob);
window.location.href = url;

This does nothing. If i change it to:

var blob = new window.Blob(['Hello, world!'], {type:
'text/plain;charset=utf-8'});
window.URL = window.URL || window.webkitURL;
var url = window.URL.createObjectURL(blob);
window.open(url);

it opens a new tab with correct URL (blob:http%3A//10.128.52.86
%3A8080/8d84447a-bdf1-4ee4-9b55-72f8159a687c) but with no content.

This features are working on any other platform/browser (except for IE of
course...).

*Expected behavior:*
I would expect the browser to show plaintext file with text "Hello, world!".

*Version: *35.0.1916.41 Chrome on iOS 7.1.1

Is there any known workaround? Thank you

Chrome for iOS is not really Chrome (in terms of the rendering engine and
JavaScript engine), it is a Chrome skinned Mobile Safari (with a lower
JavaScript performance due to platform limitations up to and not including
iOS 8).
So if it works in Mobile Safari, it should work in Chrome for iOS. Have you
tried Mobile Safari?

Yes, Mobile Safari works (if that's the browser that is installed by
default on iPad).

Hi Tomas-

I am encountering the same issue using a blob generated by filesaver.js.
Were you able to get the blob to load in a new page? Any insight would
help.

Best,
Alek

Hi,

I've solved it only by a workaround. See my stackoverflow question (and
answer) here
<http://stackoverflow.com/questions/24485077/how-to-open-blob-url-on-chrome-ios>
.

I hope it helps you. Good luck :)
