When I use puppeteer js web crawler, in waitForSelector
handler I can use console.log
without trouble:
page
.waitForSelector('input[value=update]')
.then(() => {
console.log('this is');
console.log('it');
});
But I have an error when I want to interact with DOM:
page
.waitForSelector('input[value=update]')
.then(() => {
const inputValidate = await page.$('input[value=update]');
});
This code triggers this error:
const inputValidate = await page.$('input[value=update]'); ^^^^

Do you know how to intercat with DOM in a waitForSelector
handler without trigger an error?
async
in.then(() => (...)
. It should be.then(async () => (...)
. I don't know if this will resolve your error though. – tomahaug
