var testV = 1;

var pass1 = prompt('Inserisci la Password');

while (testV < 3) {

if (!pass1) history.go(index.htm)

if (pass1.toLowerCase() == "luca") {

alert('La tua password è esatta');

break;

}

testV+=1;

var pass1 = prompt('Sbagliato! Puoi riprovare.','Password');

}

if (pass1.toLowerCase()!="altro" & testV ==2) history.go(dvd/nx.htm);

return " ";

}

document.write(passWord());

To make sure that user does enter a value in the password field you wil need to compare the password string witht the empty value,something like this

if(pass1!=""){//password is not empty

}else{//password is empty
//show password field here again
}
