How can I wait for ajax completed after click button in puppeteer crawler?

Question

Example:

await page.evaluate(() => {
    $.ajax()...
});

Then, I will get all elements on the page to continue to crawl.

Answer 1

you can use evaluate callback as an async function, like this:

await page.evaluate(async () => {
    const result = await $.ajax({
    });

    // do something with result here
});

the outer await on page.evaluate will then wait for the ajax to finish before continuing
