[javascript] tekstbestand openen

[Verwijderd]

Hoe kan ik met behulp van javascript een bestand openen om bijvoorbeeld een regel te lezen?

JS = clientside... Weten ze meer van in W&G

Geript van www.scottandrew.com:

code:

// readFile
// retrieves the contents of a local file as a JS string.
// NS4 requires Java enabled.
// Works in Mozilla 0.9.5 +

function readFile(url)
{
  var req;
  if (document.all){
    req = new ActiveXObject("Microsoft.XMLHTTP");
  }
  else if (netscape){
    if (document.getElementById){
      req = new XMLHttpRequest();
    }
    else {
      req = new NS4HttpRequest();
    }
  }
  req.open("GET",url,false);
  req.send(null);
  return req.responseText;
}

function NS4HttpRequest()
{
  this.url = "";
  this.responseText = "";
}
NS4HttpRequest.prototype.open = function(method,url)
{
  this.url = url;
  this.method = method||get;
}
NS4HttpRequest.prototype.send = function()
{
  // thank you Mr. Pemberton
  if (this.url=="") return false;
  var line,buffer;
  this.responseText = "";
  buffer = new java.io.BufferedReader(new java.io.InputStreamReader(new java.net.URL(this.url).openStream()));
  while ((line = buffer.readLine())!=null) this.responseText+=line + "\n";
  if (buffer!=null) buffer.close();
  return true;
}

IE5+, Moz & NS4+ compatible....
