[Bug]: How do I get the variables, classes, or functions in the JS script injected into the page via `add_init_script`

Version

1.52.0

Steps to reproduce

I have a js fileana.js：

var analyzer = function {
  
  this.analyze = function(){
    ……
    let listeners = getEventlisteners(element);
    ……
    }
}


const analyzer = new Analyzer()

1.I injected through page.add_init_script(path=./ana.js) .

2.I tried page.evaluate("analyzer.analyze()") called analyzer.analyze, but failed

3. I tried to use cdpSession and the call also failed

Is here any solution?

Expected behavior

I called successfully!

Actual behavior

failed!!

you can do: globalThis.analyzer = new Analyzer()

and then later on globalThis.analyzer.analyze()

Could you try that?

Thank you, It's a great way! But, I can't understand that why injetced things must be binded on globalThis also as window in playwright.

Also, I have another question how can I access InjectedScript was injected playwright own.

There is no way of accessing Playwright's InjectedScript. globalThis and window are the same.
