Javascript in html write to file

I am trying to write to a file from an html form, however the write part of the javascript doesn't do anything...

Only the validate part of the script seems to be working...

**How much do I have to write in order for stackoverflow to allow me to post something ? "It looks like your post is mostly code; please add some more details."

Answer

I pulled out my general .HTA read/write routines and dropped them in here for you.

  • Removed the XHTML stuff and switched to the HTML 5 doctype
  • Cleaned up markup to be HTML5 compliant.
  • Fixed the ID's in your INPUTS. The label element matches by ID, not name.
  • Added a return false to your form.

General notes:

  • Only constructors should start with a capital letter.
  • This must be saved with a .HTA file name
  • Needless to say, this is windows only.

<!doctype html>
<html>

<script>

var ie_writeFile = function (fname, data) {
    var fso, fileHandle;
    fso = new ActiveXObject("Scripting.FileSystemObject");
    fileHandle = fso.CreateTextFile(fname, true);
    fileHandle.write(data);
    fileHandle.close();
  };

var ie_readFile = function (fname) {
    try {
      fso = new ActiveXObject("Scripting.FileSystemObject");
      var fso, filehandle, contents;
      filehandle = fso.OpenTextFile(fname, 1);
      contents = filehandle.ReadAll();
      filehandle.Close();
      return contents;
    } catch (err) {
      return null;
    }
  };



function Write(input1, input2)
{
    var s = input1 + "," + input2;
    ie_writeFile("test.txt", s);
}

function validateForm() {
    var x1=document.userform.pwd.value;
    var x2=document.userform.re_pwd.value;
    if (x2 == x1){
        Write(document.userform.user.value, document.userform.pwd.value);
    }
    else{alert("Passwords are not the same, Re-enter password");}
}
