How to run some actions synchronously in an async function?

maharishipachecoposted in #help-playwright

Hi, I need to run two actions synchronously in an async function. How can I do this? If I await every step when playwright switches between browser_contexts, the previous step is lost, so when it comes back I cannot find what it was doing. How can I link 2 steps together in a single block?

These are currently my two lines of code

await page.get_by_role("textbox", name="To").fill(destination)
await page.get_by_text(destination, exact=True ).click()

What I would need is something like:

await page.get_by_role("textbox", name="To").fill(destination)
page.get_by_text(destination, exact=True ).click()

But I get an error if I try to run this code. In essence, once it fills the destination information in the cell, it has to immediately click on the text that appears. If it switches to another tab it will be lost.

This thread is trying to answer question "How can the user run two actions synchronously in an async function without losing the previous step when playwright switches between browser contexts?"

You should have a different page object for each tab

Hmm, I do. I create a completely dfferent browser context and page for each tab

tphillips8117May 25 4:23 AM

your first two lines of code should work fine if you are dealing with the same page object

what error are you getting?

maharishipachecoMay 25 4:26 AM

for some reason it is not working. when playwright switches between browswer contexts, the dropdown options disappear

tphillips8117May 25 4:26 AM

why is playwright switching between browser contexts?

maharishipachecoMay 25 4:26 AM

I am getting a timeout error because it has nothing to click

maharishipachecoMay 25 4:27 AM

so i can use dfferent proxies on eac

tphillips8117May 25 4:27 AM

you're switching browser contexts between the fill() and the click()?

maharishipachecoMay 25 4:28 AM

no! I am running 3 async searches, each on its own browser context so each has a different proxy.

maharishipachecoMay 25 4:29 AM

when my function gets to the two lines above. PW somtimes switches between tabs while the info is loading. but by the time it comes back the option in the dropdown menu has disappeared, hence i get a timeout error, since it can't find anything to click

How are you running the 3 searches? in a Promise.all() or something?

tphillips8117May 25 4:30 AM

Or are you running 3 browsers at once?

tphillips8117May 25 4:31 AM

(3 "projects"?)

maharishipachecoMay 25 4:31 AM

yes, 3 projects asynchronousl

tphillips8117May 25 4:31 AM

does it work in headless mode?

tphillips8117May 25 4:31 AM

(You're mentioning tabs, but you mean browser windows)?

maharishipachecoMay 25 4:32 AM

yes, exactly. sorry

maharishipachecoMay 25 4:33 AM

and no, it was not working on headless either, that is why I began running it in headful to pinpoint the issue

tphillips8117May 25 4:34 AM

does it work with just 1 browser?

maharishipachecoMay 25 4:34 AM

yes, it does

maharishipachecoMay 25 4:43 AM

so, is there a way to link both instructions in a synchronous block?

Can you share more of your code? You were mentioning you create multiple browser contexts but I don't see where you do that, and I don't see how you coordinate the actions on multiple browser contexts.

My hunch is that something is wrong there.

And do you use any threading?
