So now, I need to write a chrome extension.
From Chrome Dev Tools: <page context> and <top frame>?, I saw a drop down with text "top frame". Good. I know how to use it.
What I want to do is:
Like for example, there is a frame called "gbsf" in the page. In the frame "gbsf", there is a function called "writeOutput". I want to run this function. How can I do this, or, can I do this?
