    text
    copied!<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>
