sorun i ajax2 dosyayı göndermek için nasıl anlamaya cant ben bunu hata ayıklama zaman .php i olsun bu

Array 
(
    [act] => savefunction FormData() { [native code] } 
)

Eğer FormData kullanarak bir ajax isteği daha fazla alan eklemek isterseniz, nesneye veri eklemek gerekir

ayrıca $ .ajax'ın FormData ile çalışması için contentType ve processData değerini false olarak ayarlamanız gerekir.

$.ajax({ 

    type:"POST", 
    url:"ajax2.php", 
    data: formData, 
    contentType: false, 
    processData: false, 
    success: function(data){ 

     alert(data); 
    } 
});
