Binary data in the browser

Question

I'm using .overrideMimeType('text/plain; charset=x-user-defined'); on my XMLHttpRequest object to load a binary datafile into javascript. I'm able to get the data byte by byte with data.charCodeAt(pos) & 0xff;

This works great in FF and Chrome (The two browsers I've tested so far). I've not yet tested Safari - but I would guess that it will work. Everything I've read is that IE (including 9) and Opera do not support this.

For IE is there any alternative I can use? An ActiveX control possibly? Is there an alternative in Opera that I can use?

Answer 1

I had to use some VBScript to get it to work.

See how do I access XHR responseBody (for binary data) from Javascript in IE?
