Write file into current folder using HTML5 and JavaScript

Question

Hi I am trying to write the text file using HTML using below code..

function onInitFs(fs) {
     fs.root.getFile('paths.txt', { create: true }, function (fileEntry) {
        fileEntry.createWriter(function (fileWriter) {                            
                        fileWriter.onwriteend = function (e) {
                            alert('Paths are Stored :-)');
                        };
                        fileWriter.onerror = function (e) {
                            alert('Write failed: ' + e.toString());
                        };
                        var bb = new (window.BlobBuilder || window.WebKitBlobBuilder)();
                        bb.append($.stringify(options));                            
                        fileWriter.write(bb.getBlob('text/plain'));
          }, errorHandler);
     }, errorHandler);

  }

But as per my knowledge it is storing in the Temporary memory. But I just want to put the file in the same folder where this function is placed(HTML5). For example if I am running a file from a domain Project/html/. When I call that function it should write the text file in same directory.

Please let me know whether it is possible or not?

I guess you are aware of that the FileWriter API is still only supported by Chrome, so its pretty much a nono in any serious app. However, did you call webkitStorageInfo.requestQuota() with the PERSISTENT flag ?

That is required to have files keep stored. Afaik, Chrome will never really write files down to disk. It's pretty much a sandbox environment, like an own little database which fakes a filesystem.

But that knowledge only comes from my own little experiments, someone will correct me if I'm wrong.

Any way to achieve this using Ajax?

This article explains the use of the PERSISTENT flag and requesting quotas in more depth: http://www.html5rocks.com/en/tutorials/file/filesystem/

But FileWriter is only a draft so far, it's in Firefox's roadmap but there's no definite date for it: https://wiki.mozilla.org/Features/Platform/FileWriter
