function verificaNume(nume,raspuns) {

if (raspuns !='') {

mesaj = document.getElementById('existaEroare');

if (raspuns == 1)

 

mesaj.className='eroare';

 

else

 

mesaj.className='ascuns';

}

else

{

 

incarcaXML('verifica.php?nume=' + nume);

 

}

}

 

var cerere;

 

function incarcaXML(url) {

if (window.XMLHttpRequest) {

 

cerere= new XMLHttpRequest ();

 

cerere.onreadystatechange = trateazaCererea;

cerere.open("GET", url, true);

cerere.send(null);

}

}

 

function trateazaCererea () {

if (cerere.readyState == 4){

if (cerere.status==200) {

raspuns= cerere.responseXML.documentElement;

alert (raspuns);

var n = response.getElementsByTagName('metoda')[0].firstChild.nodeValue;

    alert(n);

 

metoda=raspuns.getElementsByTagName('metoda')[0].firstChild.data;

    alert(metoda);

 

rezultat= raspuns.getElementsByTagName('rezultat')[0].firstChild.data;

 

eval ( metoda + '(\'\', rezultat)');

}

else {

alert ("a aparut o problema" + cerere.statusText);

}

}

}

Please

your code.

 

To use the .responseXML method, you need to send a header telling the data you're sending is XML, otherwise, your browser will treat is as regular text. Also, that method ONLY works in Firefox right now. IE 7 and lower will not work. I do not recommend it.

Assure you have correct header type in your <<verifica.php?nume=' + nume>> file if is dynamic generated. Firefox return error in xml interpretation /parsing

 

<?header('Content-type: application/xml; charset="utf-8"',true);?>

<myxml><root>Hello world!</root></myxml>

The problem here appears to be variable scope to me.  cerere holds the class so this is a little counter-intuitive.  You would think that a method of the class that is held in a variable would have access to that variable, but I'm pretty sure it doesn't work that way.

 

 

Look into variable scope.
