I need to read a file which contains a group of symbols moved 65 in ASCII table. It means, for each symbol I am meant to do: String.fromCharCode('¢'.charCodeAt(0)-65) // returns 'a' But it is not working at all. I have asked friends of mine to do the test using Python inputting the same file and they got the correct result. When I try to do the same work with Chrome File System it does not work at all. I can't get back the expected symbols. I think it is a problem with my encoding/charset plataform but I can't figure out what is and how fix it. I have tried opening the file with other encoding

webkitStorageInfo.queryUsageAndQuota() is used to find out the usage stats of the files that have been stored in the file system using the HTML5 file system API I suppose. Can anyone give me the details that can be obtained in the callback provided to this function. window.webkitStorageInfo.queryUsageAndQuota(webkitStorageInfo.PERSISTENT, function() { //what all details can be obtained in this function as its arguments? }) Replace function(){...} with console.log.bind(console) , and you will find out. > window.webkitStorageInfo.queryUsageAndQuota(webkitStorageInfo.PERSISTENT, console.log.bind

How can I move a file using the URL I get from the Camera? neither successCallback nor errorCallback is called by the function moveTo. Can anyone tell me what I am doing wrong and what a possible solution looks like? function successCallback(entry) { console.log("New Path: " + entry.fullPath); alert("Success. New Path: " + entry.fullPath); } function errorCallback(error) { console.log("Error:" + error.code) alert(error.code); } // fileUri = file:///emu/0/android/cache/something.jpg function moveFile(fileUri) { newFileUri = cordova.file.dataDirectory + "images/"; oldFileUri = fileUri; fileExt =

I am trying to use saveAs interface as explained here For the moment, I only worry about Google Chrome, and I uses latest Canary (Version 27.0.1429.0 canary) Qn1: the article says. The W3C File API includes a FileSaver interface, which makes saving generated data as easy as saveAs(data, filename), though unfortunately it will eventually be removed from the spec. Why it would be removed? Qn2: Below code. if (window.saveAs) { window.saveAs(blob, name); }else{ console.log("saveAs not supported") } prints saveAs not supported So chrome doesn't support saveAs. That is not the impression I have

Is it possible to use the HTML 5 File API (for example, this library: https://github.com/23/resumable.js ) in conjunction with the S3 multi-part upload feature? http://docs.aws.amazon.com/AmazonS3/latest/dev/uploadobjusingmpu.html Yes, but you will need some kind of server backend to handle the Amazon API keys in a more secure way if you are going to make it part of a public website. You can find what looks like a complete example implementation of this these projects: s3-multipart-upload-browser which uses a PHP backend s3_multipart which uses Ruby. Please note that I have not used, tested or

In Chrome Apps, I'm downloading a blob content from a server using JavaScript XHR (Angular $http GET in particular, with response type 'blob') How should I save this to chrome application's file system? Currently using an Angular wrapper on HTML5 filesystem API https://github.com/maciel310/angular-filesystem I do not want to show user a popup (hence I can't use chrome.fileSystem. chooseEntry ) The chrome.fileSystem.requestFileSystem API is only supported by Kiosk-only apps. Hence I'm using HTML5 FileSystem API instead of chrome's. I'm using following code to make XHR to fetch blob. $http({ url
