filereader

I need some help with HTML5. I have a script that loops through all the uploaded files and gets each file details. Currently I am using HTML5 techniques that include FileReader. The FileReader function only works in Chrome and Firefox, so I am looking for an alternative which will work in all of the other browsers. I saw the Stack Overflow question Flash alternative for FileReader HTML 5 API , but I wasn't able to figure how to use this Flash thing, and aren't there any other solutions so I can loop through all of the uploaded files and get each file details (which will work in Safari and

(Am new to web programming, so apologies for any lack of rudimentary knowledge.) My page allows a user to select a file that is then read clientside & displayed in a textbox on the page. The easiest way I found to do this was to use a FileReader object, which works fine in Firefox and Chrome. This doesn't work in Safari (yet), so what should I do instead? //When the eventlistener detects a change in the input file... var file = evt.target.files[0] var reader = new FileReader(); reader.onload = function (e){document.getElementById('data').value = e.target.result}; reader.readAsText(file);

1、FileReader类 FileReader继承自InputStreamReader类，InputStreamReader类继承自Reader类。 import java.io.FileOutputStream; import java.io.FileReader; import java.io.IOException; public class FileReaderDemo { public static void main(String[] args) throws IOException { //读取文字 FileReader fr = new FileReader("E:\\IO流\\java\\1.txt"); int ch = 0; while ((ch = fr.read()) != -1) { // 输出的字符对应的编码值 System.out.print(ch); System.out.print((char) ch); System.out.println(); } //写入文字 FileOutputStream fos = new FileOutputStream("E:\\IO流\\java\\8.txt"); fos.write("读取文件".getBytes());//编码过程 fos.close(); } } 2

This question already has an answer here: Java read file got a leading BOM [  ] 6 answers If I write this code, I get this as output --> This first:  and then the other lines try { BufferedReader br = new BufferedReader(new FileReader( "myFile.txt")); String line; while (line = br.readLine() != null) { System.out.println(line); } br.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } How can I avoid it? You are getting the characters  on the first line because this sequence is the UTF-8 byte order mark (BOM) . If a text

I am building an image resize/crop, and I'd like to show a live preview after they've edited it in a modal (bootstrap). This should work, I believe, but I just get 0 in console.log. This requires feeding the width and the height of the original image into another script (which I'll do after, just need them in console.log/a variable for now) function doProfilePictureChangeEdit(e) { var files = document.getElementById('fileupload').files[0]; var reader = new FileReader(); reader.onload = (function(theFile) { document.getElementById('imgresizepreview').src = theFile.target.result; document
