[AJAX] Question sur le statut qui passe de 1,2,3,4 et puis 1
Bonsoir,
J'ai mis un alert comme ceci :
Code:
1
2
| alert(xhr2.readyState);
if(xhr2.readyState == 4 && (xhr2.status == 200 || xhr2.status == 0 ) ) |
Est-ce normal que j'obtienne :
1,2,3,4 et puis 1
C'est le dernier 1 qui m'intrigue.
MA liste déroulante ne se remplit pas en tout cas.
Voici mon code ajax :
