What is the difference in using window.resolveLocalFileSystemURL vs window.requestFileSystem when downloading files with the cordova file plugin? I cant find any documentation on resolveLocalFileSystemURL but it works fine, and its easier to use? Which one should I use for simple CRUD operations in a cordova app? (I use cordova 3.4.0-0.1.3) I use it like this: function onResolveSuccess(fileEntry) { fileEntry.file(function(file) { var reader = new FileReader(); reader.onloadend = function(evt) { var _machines = JSON.parse(evt.target.result); machinesCache.setMachines(_machines.AllMainCategories

The following code (vendor normalized) works perfectly fine and displays "➀➁➂ Test" in Firefox 8, but displays "➀âžâž‚ Test" in Google Chrome. Is there any way to preserve encoding of blobs in Google Chrome short of writing a file to a temporary filesystem using the filesystem API? var bb = new BlobBuilder; bb.append("➀➁➂ Test"); var b = bb.getBlob("text/plain;charset=UTF-8"); var url = URL.createObjectURL(b); open(url); Gecko (Firefox), WebKit (Safari, Chrome) and Opera support the non-standard btoa function for encoding a string in base 64. In order to get a base 64 string containing a

I am using Google Web Toolkit for a project and would like the user to select a text file to open in a text window inside the browser. Here's the almost working code: private DialogBox createUploadBox() { final DialogBox uploadBox = new DialogBox(); VerticalPanel vpanel = new VerticalPanel(); String title = "Select a .gms file to open:"; final FileUpload upload = new FileUpload(); uploadBox.setText(title); uploadBox.setWidget(vpanel); HorizontalPanel buttons = new HorizontalPanel(); HorizontalPanel errorPane = new HorizontalPanel(); Button openButton = new Button( "Open", new ClickHandler() {

Is it possible to make file uploads resumable after page redirect / browser restart through Resumable.js or any other Javascript API? (I seriously miss NPAPI here) 来源： https://stackoverflow.com/questions/34131621/resumable-js-persist-file-uploading-between-redirects-and-browser-restarts

I barely made websocket file upload function. But uploading speed seems to be slow. I have used Java API for websocket Server and javascript for client. Server: package websocket; import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.nio.ByteBuffer; import javax.websocket.CloseReason; import javax.websocket.EndpointConfig; import javax.websocket.OnClose; import javax.websocket.OnError; import javax.websocket.OnMessage; import javax.websocket.OnOpen; import javax.websocket.Session; import javax.websocket.server

I am looking for a fast hash with low collisions implemented in JavaScript. It doesn't need to be a crypto hash. I am basically using it as a way to see if a given file has already been uploaded (or partially uploaded) to a user's account to save them some upload time on large (video) files. I am using the new HTML5 File API to read in slices of the file. I then hand this off to SparkMD5 to give me a hash of the file. I like the fact that SparkMD5 allows me to do an incremental hash so I don't have to read the entire thing in memory. Overall, SparkMD5 works for my needs but for large files it
