On a site I am trying to access a function inside a userscript to call it with a custom argument except I can only find it by typing on Chrome's console the following :

getEventListeners(window).keydown[0].listener

or by looking at the event listeners directly on the section under the HTML document on Chrome

This function comes from a script which can be found in the sources here:

Does anybody know how can I access that function?

Here is the client.js: https://raw.githubusercontent.com/GodWoold/code/master/client.js and the function I am looking for is located line 157 and you can find it by searching for:

b(b){++q.di;q.Mi=a;q.tj();a.Sf(b);q.tj();--q.di}

Access for what reason? What's the end goal here? Knowing that we might be able to tell you if it's even possible – evolutionxbox May 25 '20 at 13:29
@evolutionxbox the goal is to be able to trigger that function with a custom argument – Woold May 25 '20 at 13:32
It really depends on how the handler is defined in client.js... – evolutionxbox May 25 '20 at 13:34
@evolutionxbox I edited my post and added these information – Woold May 25 '20 at 13:39
It looks like it's in a closure. I don't think you can reference it directly. Maybe you'll need to attach your own handler? – evolutionxbox May 25 '20 at 13:42
what does a closure means, I can't access this function directly? – Woold May 25 '20 at 13:47
@evolutionxbox attaching my own handler won't be possible as I don't know how that function really works – Woold May 25 '20 at 13:59
Read https://stackoverflow.com/questions/36636/what-is-a-closure first and then https://stackoverflow.com/questions/16722489/javascript-access-function-in-closure – evolutionxbox May 25 '20 at 14:00
@evolutionxbox thanks, I read those, is there any way to get that variable out of the closure or do you know if i can modify the script before it executs on the website? – Woold May 25 '20 at 14:09
https://stackoverflow.com/a/16722552/989920 - no I don't think so – evolutionxbox May 25 '20 at 14:12
