I have one issue that I can't fix, maybe one of you have an idea on how to figure it out
While automating Chrome thanks to Chrome.ahk, I am facing an issue with a small popup window, the kind you get with a "Javascript: alert('Hello World!')" command.
This window will appear when I am sending a wrong request to my website.
I'd like to detect this window and close it ("ok" button).
Code: Select all
CloseAlert: If (WinExist("Hello World!")) { WinActivate Send, {enter} } Return SetTimer, CloseAlert, 100

Thanks for the feedback. Unfortunately, I tried but I could not make it work, are you sure these alerts can be detected by WinExists ? I tried to make it work with
WinExist("Hello World!")
and
WinExist("www.google.com says")
Thank,s

If you're actually just sticking to a single instance, then that's fine, however you might want to check that you're not doing PageInst := ChromeInst.GetPage() at all elsewhere in the script while it's running, or at least assign a different variable for a second instance if you are, otherwise it'll overwrite it and be unable to disconnect the first instance. Otherwise you can expect it to keep calling back to the class repeatedly while that instance is active. Not sure what editor you're using, but it's definitely annoying when trying to step through, I'm using VSCode and I'm not sure if there's a way to have exclude some methods or routines while debugging.Vaggeto wrote: ↑17 Dec 2020, 22:43Hmmm...

In the console you can manually change the javascript context and the commands work, but is it possible using Chrome.ahk to direct commands at a specific context? From what I can tell firefox supports a cd() command which changes the context but I'm not having luck finding something similar with Chrome.
If this isn't possible, am I wrong that that basically leaves Iframes essentially untouchable?
Thanks!
