const browser = await puppeteer.launch({
headless:false
})
const page = await browser.newPage()
await page.goto(url,{
networkIdle2Timeout: 5000,
waitUntil: 'networkidle2',
timeout: 3000000});
const getData = await page.evaluate(() =>
Array.from(document.querySelectorAll('.player__name,.player__health,.player__armour'))
.map(player => ({

armour: player.value,
}))

Tried to do everything in different functions but I need everything in one element

I'm trying pick some data from followers page, but always return a empty array.
That's my code:
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({headless:false});
const page = await browser.newPage();
await page.goto('https://www.instagram.com/accounts/login/', {
waitUntil: 'networkidle0',
});
// Wait for log in form
await Promise.all([
page.waitForSelector('[name="username"]'),
page.waitForSelector('[name="password"]'),
page.waitForSelector('[type="submit"]'),
]);
// Enter username and password
await page.type('[name="username"]', 'yourAccount');
await page.type('[name="password"]', 'yourPassword');
// Submit log in credentials and wait for navigation
await Promise.all([
page.click('[type="submit"]'),
page.waitForNavigation({
waitUntil: 'networkidle0',
}),
]);
await page.goto('https://www.instagram.com/publicProfile /followers/', {waitUntil: 'networkidle0'});
const teste = await page.evaluate(() => {
const followers = document.querySelectorAll("._aaco span");
let followersArray = []
followers.forEach((item) =>{
followersArray.push(item.innerText)
})
return followersArray
})
console.log(teste)
await browser.close();
})();
publicProfile in the URL is a profile that I choose, but for privacy reasons e alterate for publicProfile.
UPDATE: The problem has resolved, as Örvar said the problem was that I wasn't logged, soo I search for help here and I found this (Puppeteer Login to Instagram) question that solved my question.
When you use a tool like Puppeteer to get content from a site where you need to login, you also need to login using Puppeteer, so the site that you are logging into will generate a user cookie.
Log into Instagram using Puppeteer with user credentials
When Puppeteer has logged in with user credentials, you can run the code you have posted above.
I'm trying to make a InstagramBot that logs in and then go to some profile, my code worked yesterday for awhile and than it just stopped working .
I've tried to clone my repository from github, but it does'n work either, sometimes it works again, but if I try to create another function, the code just ignore the line of the code that changes the page.
I've also tried to create a new page and then in this new page use the goto function and it worked, but the account doesn keep logged in
The version of puppeteer that I'm using: 1.16.0
The version of node.js that I'm using: v10.15.3
const puppeteer = require('puppeteer');
const BASE_URL = "https://www.instagram.com/accounts/login/?hl=en&source=auth_switcher";
const instagram = {
browser: null,
page: null,
profile_url: null,
initialize: async (profile) => {
instagram.browser = await puppeteer.launch({
headless: false
})
instagram.profile_url = await "https://www.instagram.com/" + profile;
instagram.page = await instagram.browser.newPage();
await instagram.page.goto(BASE_URL, {waitUntil: 'networkidle2'});
},
login: async(username, password) =>{
await instagram.page.waitFor(1000);
await instagram.page.type('input[name="username"]', username);
await instagram.page.type('input[name="password"', password);
await instagram.page.click('button[type="submit"]');
await instagram.page.waitFor(1500);
await console.log(instagram.profile_url);
await instagram.page.goto(instagram.profile_url, {timeout: 0, waitUntil: 'domcontentloaded'}); // the code just ignore this line
await instagram.page.waitFor(1000);
},
getPhotosLinks: async() => {
console.log("Do something here");
}
}
module.exports = instagram;
It doesn't give any error message, just doesn't work
Replace
await instagram.page.click('button[type="submit"]');
await instagram.page.waitFor(1500);
with
await Promise.all([
instagram.page.click('button[type="submit"]');,
instagram.page.waitForNavigation()
]);
and see if it works
Selecting an input element and filling it with a certain value is straight forward
Element
<input class='foo' type="test" name="userName" placeholder="Enter Your Name..." />
Code with click() function
(async () => {
const browser = await puppeteer.launch({
headless: false,
args: [
'--incognito'
]
});
const page = await browser.newPage()
await page.goto('...')
await page.type('input[name=userName]', 'test#test.com')
....
})();
I use input[name=userName] to select the wanted HTML Element.
However, when I try this with <span /> and the text attribute, it's not working.
Element
<span text="foo" id class="bar" />
Code with click() Function
(async () => {
const browser = await puppeteer.launch({
headless: false,
args: [
'--incognito'
]
});
const page = await browser.newPage()
await page.goto('...')
await page.type('input[name=userName]', 'test#test.com')
....
await page.waitForNavigation({ waitUntil: load })
await page.click('span[text=foo]'); // <-- not working
})();
Is there a straight forward way to select other elements than input by their values attached to their attributes?
The load in await page.waitForNavigation({ waitUntil: load }) was not set into '' which caused the <span /> not to be there, after the button to log in was clicked...
Not familiar with Puppeteer. But in Vanilla JavaScript you could do:
document.querySelector('span[text="foo"]');
After a little digging, looks like the below is how you could do it in Puppeteer.
const spanText = await page.evaluate(() => document.querySelector('span[text="foo"]'));
I'm using Puppeteer for doing some web scraping and I'm having troubles. The website I'm trying to scrape is this one and I'm trying to create a screenshot of a calendar that appears after clicking the button "Reserve now" > "Dates".
const puppeteer = require('puppeteer');
const fs = require('fs');
void (async () => {
try {
const browser = await puppeteer.launch({headless: false});
const page = await browser.newPage();
await page.goto('https://www.marriott.com/hotels/travel/reumd-le-meridien-ra-beach-hotel-and-spa');
await page.setViewport({ width: 1920, height: 938 });
await page.waitForSelector('.m-hotel-info > .l-container > .l-header-section > .l-m-col-2 > .m-button');
await page.click('.m-hotel-info > .l-container > .l-header-section > .l-m-col-2 > .m-button');
await page.waitForSelector('.modal-content');
await page.waitFor(5000);
await page.waitForSelector('.js-recent-search-inputs .js-datepick-container .l-h-field-input')
await page.click('.js-recent-search-inputs .js-datepick-container .l-h-field-input');
await page.waitFor(5000);
await page.screenshot({ path: 'myscreenshot.png'});
await browser.close();
} catch (error) {
console.log(error);
}
})()
This is what myscreenshot.png should contain:
but I'm getting this instead:
As you can see, myscreenshot.png doesn't contain the calendar. I don't understand what I'm doing wrong since I click on the right node and I even give time enough to it for loading everything.
Thank you in advance!
Edit: I forgot to say that I have also tried Puppeteer recorder in order to achieve this and I haven't had luck either.
As you have many .l-h-field-input elements, I would try being more specific there.
This worked for me:
await page.click('.js-recent-search-inputs .js-datepick-container .l-h-field-input');
I am trying to grab some html after a input tag button is clicked. I am clicking the button with page.evaluate() since page.click() does not seem to work for an input tag button. I have tried visual debugging with headless:false in the puppeteer launch options to verify that the browser indeed navigated to the point after the button is clicked. I am unsure as to why page.content() returns the html before the button is clicked rather than the html after the event happens.
const puppeteer = require('puppeteer');
const url = 'http://www.yvr.ca/en/passengers/flights/departing-flights';
const fs = require('fs');
const tomorrowSelector = '#flights-toggle-tomorrow'
puppeteer.launch().then(async browser => {
const page = await browser.newPage();
await page.goto(url);
await page.evaluate((selector)=>document.querySelector(selector).click(),tomorrowSelector);
let html = await page.content();
await fs.writeFile('index.html', html, function(err){
if (err) console.log(err);
console.log("Successfully Written to File.");
});
await browser.close();
});
You can click on the label for the radio. Also, you need to wait for some sign of changed state (for XHR/fetch response or new selectors). For example, this code works for me, but you can use any other condition or just wait for some seconds.
const fs = require('fs');
const puppeteer = require('puppeteer');
const url = 'http://www.yvr.ca/en/passengers/flights/departing-flights';
const tomorrowLabelSelector = 'label[for=flights-toggle-tomorrow]';
const tomorrowLabelSelectorChecked = '.yvr-form__toggle:checked + label[for=flights-toggle-tomorrow]';
puppeteer.launch({ headless: false }).then(async (browser) => {
const page = await browser.newPage();
await page.goto(url);
await Promise.all([
page.click(tomorrowLabelSelector),
page.waitForSelector(tomorrowLabelSelectorChecked),
]);
const html = await page.content();
await fs.writeFile('index.html', html, (err) => {
if (err) console.log(err);
console.log('Successfully Written to File.');
});
// await browser.close();
});
