    File.getAsText

    Non-standard
    This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

    Deprecated since Gecko 7.0 (Firefox 7.0 / Thunderbird 7.0 / SeaMonkey 2.4)
    This feature has been removed from the Web. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

    Summary

    The getAsText method provides the file's data interpreted as text using a given encoding.

    Note: This method is obsolete; you should use the FileReader method readAsText() instead.

    Syntaxe

    var str = instanceOfFile.getAsText(encoding);

    Parameters

    encoding
    A string indicating the encoding to use for the returned data. If this string is empty, UTF-8 is assumed.

    Returns

    A string containing the file's data interpreted as text in the specified encoding.

    Example

    // fileInput is a HTMLInputElement: <input type="file" id="myfileinput" multiple>
    var fileInput = document.getElementById("myfileinput");
    
    // files is a FileList object (similar to NodeList)
    var files = fileInput.files;
    
    // object for allowed media types
    var accept = {
      binary : ["image/png", "image/jpeg"],
      text   : ["text/plain", "text/css", "application/xml", "text/html"]
    };
    
    var file;
    
    for (var i = 0; i < files.length; i++) {
      file = files[i];
    
      // if file type could be detected
      if (file !== null) {
        if (accept.text.indexOf(file.mediaType) > -1) {
          // file is of type text, which we accept
          // make sure it's encoded as utf-8
          var data = file.getAsText("utf-8");
          // modify data with string methods
    
        } else if (accept.binary.indexOf(file.mediaType) > -1) {
          // binary
        }
      }
    }
