Only one handlePageFunction for each crawler？

[hugetiny]

I want to page.$$eval or page.$eval different selectors for diffrent page levels in a recursive crawler.
But there is only one handlePageFunction for each crawler.

Do I have to write anothor handlePageFunction in anothor crawler？

Yes, one crawler have one page handler. Have you seen the getting started guide? It shows how you can label requests via request.userData and implement routing based on it, so you have different handlers for different types of requests.

request.userData is static in INPUT.json
Can I add label dynamically for next requests when I use enqueueLinks function

[hugetiny]

I find out that pseudoUrls is not available for userData

Not sure if you read the getting started guid I linked here, if not, please do so, as it describes this use case.

request.userData is static in INPUT.json

This has nothing to do with INPUT.json, you add userData to the requests you are adding to the req queue or req list. It is your code that is processing the input (unless you are using some public actor? but I'd expect you would mentioned that...)

Can I add label dynamically for next requests when I use enqueueLinks function

Yes you can, via transformRequestFunction option:

I find out that pseudoUrls is not available for userData

Not sure what you mean by that. As said above, you can use transformRequestFunction to dynamically add userData to the requests that are being enqueued.

Maybe share some code if you want more help.
