freezed script

Hi!

Is it possible to somehow stop (set a pause) the script. For example, when a modal window appears, stop the script execution, while closing the window, then defrost the script. I try this:

await page.waitForSelector('div[class="popup _active"]').then(async()=>{

	console.log('catch popup');

	page.click('span[class="submit"]').then(()=>{
		console.log('click confirm');
	});

	await page.waitForSelector('div[class="popup _active"]',{hidden:true}).then(()=>{
		console.log('el hidden');
	});
});

But it does not freeze script.

Is it possible to implement without using flags to make the script more flexible?

Sure, I’ll close this for now. Feel free to re-file with more details if you continue to experience issues.

I’ll explain now. In the block where the button is pressed further, the waiting time is set. Because when the cycle starts again, the page does not have time to load and the condition of pressing the button works again (ie, the product is parsed again from the first page). You can comment out waitForNavigation because if you leave only it, the script hangs after clicking on the button next, and waitForNavigation does not see the page load.

@Trahtenberg I’d appreciate an explanation in layman terms that doesn’t refer to code - to help us understand what’s going on.

Now the question itself is how to organize the script in such a way that, using the minimum, waitFor(seconds)?

if you’re testing your own website, then I’d recommend set up certain hooks on the page that help you test it. The usual practice is to use data attributes on elements and then wait/query for them with page.waitForSelector/page.$. Other nice approach is to use console.timeStamp to yield certain events - you can listen to them on the puppeteer side using page.on('metrics') event.

If you’re dealing with a website as a black box, then there’s no silver bullet and all solutions vary a lot in creativity. Sometimes tracking certain network requests using page.on('requestfinished') works nicely, sometimes there’s a specific DOM element that you can wait for.
