I'm playing around a bit with the FileSystem API.
I've found a lot of examples where you generate a download link and let the user download the file the "browser way".
I would like to know two things:
Is there any way to write the ajax result in the fiddle as a file directly to the disk (without any type of prompt). Like to the user's desktop for example.
Is blob the most suitable format for this?
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function(){
if (this.readyState == 4 && this.status == 200){
console.log(this.response, typeof this.response);
var img = document.getElementById('img');
var url = window.URL = window.webkitURL;
img.src = url.createObjectURL(this.response);
}
}
xhr.open('GET', 'http://www.newyorker.com/online/blogs/photobooth
/NASAEarth-01.jpg');
xhr.responseType = 'blob';
xhr.send();
Please note that Filesystem API is no longer part of the standard's specification, as specified at: http://www.w3.org/TR/file-system-api/
EDIT: Quoting the specification in case the link changes: "File API: Directories and System W3C Working Group Note 24 April 2014
Work on this document has been discontinued and it should not be referenced or used as a basis for implementation."
(This does not relate to the question directly, but it is essential to know not to use the FileSystem API further.)
Another link: http://www.html5rocks.com/en/tutorials/file/filesystem/
"In April 2014, it was announced on public-webapps that the Filesystem API spec should be considered dead. Other browsers have showed little interest in implementing it."
