لاگین کردن به وسیله ajax و captcha بعد از اولین ورود نا موفق
من لاگین رو به صفحه ایندکس سایتم آوردم
این کد های من هست ، اگه دفعه اول وارد بشم ( که نیازی به کپتچا نداره ) به صورت صحیح وارد میشه
اگه نام کاربری یا کلمه عبور اشتباه وارد بشه کپتچا نمایان میشه ، از زمانی که کپتچا ظاهر میشه ، در صورتی که نام کاربری کلمه عبور و کپیچا صحیح هم باشه ، پیغام خطا کپتچا صحیح نیست ظاهر میشه. و لاگین صورت نمیگیره .
