Cannot get element inside Iframe. about rod

[ysmood]

Usually, you just use document.querySelector("#iframe_selector") directly on the devtools console to debug. I think you won't be able to find it in the browser either.

I see people encounter similar issues all the time. Such as when an iframe is inside another iframe you need to call Frame() for each level. Such as query shadow DOM elements, you have to use special js to handle them, etc.

If you can provide me the page I can help you to figure out the problem. If I can't reproduce your issue I'm afraid that I can't do much about it.

Here the example of nested iframes: https://github.com/ysmood/rod/blob/a072993e8f2e5b768bf92f5a517a7fca21a3e2ce/element_test.go#L36

Hm. document.querySelector("#iframe_selector") finds element under iframe context (if you select it in console manually). Can I get current iFrame name when I switched to it?

[ysmood]

Can you do something like this for me?

[ysmood]

To get the details about the iframe you can just do something like this

fmt.Println(fr.Element("#element_selector").Describe())

Make sure the src is the one you want.

Hi. It's nothing much really. Copy selector just returns: #contact-email.

You sure it's not nested iframes and not shadow dom?

[alufrew]

As far as I can see not. Here you can launch test mock code to go to iFrame. I created it for debug purposes so don't mind things like sleep. package main import ( "fmt" "time" "github.com/ysmood/rod" "github.com/ysmood/rod/lib/launcher" ) func main() { url := launcher.New(). Headless(false). // run chrome on foreground Launch() browser := rod.New().ControlURL(url).Connect() defer browser.Close() page := browser.Page("test_page") page.Element("#login_email").Input("tetst_email") page.Element("#login_submit").Click() time.Sleep(5 * time.Second) page.ElementX("//p/button[@data-fsc-item-path='test-clario-1mo']").Click() fr := page.Element("#fsc-popup-frame").Frame() time.Sleep(2 * time.Second) fmt.Println(fr.IsIframe()) fr.Element("#contact-last-name").Click() }

Rod is designed to prevent the use of time.Sleep. You can use WaitInvisible, WaitStable instead, here the example code:

package main

import (
	"github.com/ysmood/kit"
	"github.com/ysmood/rod"
	"github.com/ysmood/rod/lib/launcher"
)

func main() {
	url := launcher.New().
		Headless(false). // run chrome on foreground
		Launch()

	browser := rod.New().ControlURL(url).Connect()
	defer browser.Close()

	page := browser.Page("https://buynow.account.sz.clario.co/lumis_fastspring_bn_emulator_with_login.html")

	page.Element("#login_email").Input("[email protected]")
	page.Element("#login_submit").Click().WaitInvisible()
	page.ElementX("//p/button[@data-fsc-item-path='test-clario-1mo']").Click()

	fr := page.Element("#fsc-popup-frame").Frame()

	fr.Element("#contact-last-name").WaitStable().Click()

	kit.Pause()
}

The issue is caused by site-per-process, you can use the rod v0.25.7 to overcome it.

I thought I don't need site-per-process anymore but seems like we still have to keep it, hope in the future chrome can expose a special API for iframe to handle js injection.

Thank you for fix. It's working now. I used time.Sleep just to make sure that framework doen't hang before iFrame is loaded. It wont be used in actual code.

Good to hear that 👍
