Running JavaScript (Eval, MustEval)

[MikhailKlemin]

Hello!

I am not sure I understand how to run a custom JS script. The script works fine in chrome console, but does nothing when I try to run it via page.MustEval() on same page. Do I miss something obvious?

var js = `myevent  = $.Event('mousedown');
	elem = $('.uclw_noUi-base'); 
	pos = elem.offset().left; 
	myevent.clientX = pos; 
	myevent.clientY = 0;
	elem.trigger(myevent);`
	err := rod.Try(func() {
		page.MustSearch(".uclw_noUi-base").WaitStable(2 * time.Second)
		page.MustEval(js)
		if err != nil {
			log.Fatal(err)
		}
		page.WaitLoad()
        })
        if err!=nil{
                log.Fatal(err)
        }

Well, I understand you can't execute such JavaScript, albeit it was possible on ChromeDP.
I have rewrote it, works as intended :-)

        left := page.MustEval("$('.uclw_noUi-base').offset().left").Int()
	top := page.MustEval("$('.uclw_noUi-base').offset().top").Int()
	mouse := page.Mouse

	mouse.Move(float64(left), float64(top), 2)
	mouse.MustDown(proto.InputMouseButtonLeft)
	mouse.MustUp(proto.InputMouseButtonLeft)

The js block works fine for me, not sure how to reproduce your problem.

Sorry for late reply, I left it as is, I guess there are some issues with the site I was testing it on.
