With Playwright (JS), to wait for the screen transition,
That is the standard.
const navigationPromise = page.waitForNavigation(); await page.click('input[type="submit"]'); //Events that cause screen transitions await navigationPromise;
Or more simply
await Promise.all([ page.waitForNavigation(), page.click('input[type="submit"]'), ]);
Write like this.
By the way, how should I write this kind of processing with the Sync API (API for those who do not use async/await) of playwright-python?
The correct answer (as of version 0.170.x) is
with page.expect_navigation(): page.click('input[type="submit"]') #Events that cause screen transitions
How easy it is.
The waitFor somehow system methods are almost the same, just enclose it with the with statement and the
expect_**** method, and it will do asynchronous processing nicely. It's wonderful.
(Internal implementation, it seems that asyncio's Future is used)
