I use this code to solve the CAPTCHA ..

Sometimes there is no CAPTCHA ..

I want to make this code only works if there is CAPTCHA ..

In the case of non-appearance of CAPTCHA (or image to save) ignores the following lines ..

I heard that this is possible through Javascript ..

But I can not find a way to do that ..

Any Help? ..

Yes, you can use JavaScript.

Basically, what you need to do is check whether the captcha field do exists or not. Maybe something like this one.

function isCaptchaExists() {
    var macro = "TAG POS=1 TYPE=IMG ATTR=HREF:*captcha* EXTRACT=HTM";
    var retcode = iimPlayCode(macro);

    return retcode < 0;
}
