title: xmlhttprequest: "password" from txt-file
body: <p>I'm new to javascript/ajax and a bit stuck right now.
  The assignment is to use only javascript/ajax.</p>
  
  <p>I'm supposed to make a login-form, and when typing in the right password it will display a "secret message". Currently this message is an alert-box.</p>
  
  <p>This is in the script for validating the form input:</p>
  
  <pre><code>var riktigPassord = 'password';     
  var passord = window.document.passordSkjema.passord.value;
       if (passord == riktigPassord ) {
        alert("Dette er en hemmelig beskjed");
        window.document.passordSkjema.passord.focus();
        return true;
       }
       else {
        alert("Innlogging mislyktes. Passord er feil!");
        window.document.passordSkjema.passord.focus();
        return false;
       }
      }//slutt på funksjonen her
  </code></pre>
  
  <p>And this is the code for the form:</p>
  
  <pre><code>&lt;form name="passordSkjema" action="#" method="post" 
  onSubmit="return validerPassord();"&gt;
  Passord: &lt;input type="text" name="passord"&gt;&lt;br&gt;
  &lt;input type="submit" name="knapp"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>I'm supposed to get the password from a txt-file. (still using only javascript)
  and in my case, the txt-filename is "password.txt".</p>
  
  <p>I've never done this before, but I think I know how to make a XHR-object... xD</p>
  
  <pre><code>// New XMLHttpRequest-object
  function newXHRobjekt() {
   try {
    XHRobjekt = new XMLHttpRequest(); // Firefox, Opera, ...
   } catch(err1) {
    try {
     XHRobjekt = new ActiveXObject("Microsoft.XMLHTTP"); // Noen IE
    } catch(err2) {
     try {
      XHRobjekt = new ActiveXObject("Msxml2.XMLHTTP"); // Noen IE
     } catch(err3) {
      XHRobjekt = false;
     }
    }
   }
   return XHRobjekt;
  }
  </code></pre>
  
  <p>So.. My question is. How do I use a XHR-object to get use the functions above to check the password-input against password.txt. the file only contains the password (for instance only "12345"). and also I would like to know how to get the "secret message" from another txt-file.</p>
  
  <p>I'm aware that this isn't secure at all, but it's a part of understanding javascript/Ajax, in my classes.</p>
  
  <p>Thanks!</p>
