_FFClick function's arguments do not work

[Vitaliy4us]

There is a button on a page created with HTML code:

<div class="product_size_item                          
        sizes__button_on
        "
        data-stock="3"
        data-mdp-id="12091904"
        data-sizetype="Unspecified"
        >
        39                                                               
    </div>

Is it possible to use this data as arguments of function _FFClick () for clicking on this button? I tried these ones:

_FFClick("product_size_item sizes__button_on ", "class", 2)
_FFClick("12091904", "id")
_FFClick("12091904")
_FFCmd(".getElementById('12091904').onclick();")

but it does not work.

Sounds like the issue is something besides _FFClick. You'll need to provide some more details (a script that we can run to demonstrate the issue, output from the Scite window, etc) if you want further assistance.

Thank you for your reply. You are absolutely right. As I found out, the problem lays in another field. Actually, function

_FFClick("product_size_item sizes__button_on ", "class", 2)

works and returns 1 which means successful result. But nothing happens. I mean that the button is not really pressed. For example we have 3 buttons. If we use 0,1 or 2 as the last function's argument, the function returns 1 but no button is pressed. If we use 3, the function returns 0. The very simple code is attached:

#Include <FF.au3>

Opt("WinTitleMatchMode", 2)
WinActivate ("Mozilla Firefox")
Sleep (1000)

_FFConnect()
Sleep (1000)
_FFOpenURL ("https://modnakasta.ua/product/7499459/")
Sleep (1000)

For $i = 0 to 3
    Local $result = _FFClick("product_size_item sizes__button_on ", "class", $i)
    Sleep (1000)
    MsgBox (0, "", $result)
Next

What exactly isn't working as expected? When I run your script, each button is selected (highlighted in green) as I would expect.

​But I am not able to do the same. Any button is highlighted in green after using FFClick

Sorry but I don't understand. Exactly what isn't working for you?

​The script does nothing. The buttons are not selected (they are not highlighted in green). And now I know the reason. The reason is Firefox version. The script starts working after installing the older version (14) instead of the newest 37 version. Could you tell me what is your Firefox version?
