I'm developing a Nike SNKRS BOT to buy shoes with Puppeteer and Node.js.
I'm having issues to distinguish and .click() Size button screenshot of html devtools and front end buttons
That's my code: i'm not experienced so i have tried everything
const xpathButton = '//*
[#id="root"]/div/div/div[1]/div/div[1]/div[2]/div/section[1]/div[2]/aside/div/div[2]/div/
div[2]/ul/li[1]/button'
const puppeteer = require('puppeteer')
const productUrl = 'https://www.nike.com/it/launch/t/air-max-97-coconut-
milk-black'
const idAcceptCookies = "button[class='ncss-btn-primary-dark btn-lg']"
async function givePage(){
const browser = await puppeteer.launch({headless: false})
const page = await browser.newPage();
return page;
}
async function addToCart(page){
await page.goto(urlProdotto);
await page.waitForSelector(idAcceptCookies);
await page.click(idAcceptCookies,elem => elem.click());
//this is where the issues begin
//attempt 1
await page.evaluate(() => document.getElementsByClassName('size-grid-
dropdown size-grid-button"')[1].click());
//attempt 2
const sizeButton = "button[class='size-grid-dropdown size-grid-button']
button[name='42']";
await page.waitForSelector(sizeButton);
await page.click(sizeButton,elem => elem.click());
}
//attempt 3
await page.click(xpathButton)
//attempt 4
document.evaluate("//button[contains ( ., '36')]", document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue
async function checkout(){
var page = await givePage();
await addToCart(page)
}
checkout()
Attempt number 2 looks like the best approach, except your selector is wrong. The button does not have a name attribute, according to your screenshot, so you will need another approach, closer to attempt 3.
You can use puppeteer to select an element by with xpath, and xpath allows you to select by an element's text content.
Try this:
await page.waitForXPath('//button[contains(text(), "EU 36")]')
const [button] = await page.$x('//button[contains(text(), "EU 36")]')
await button.click()
Because the xpath selector is returning an array of element handles, I destructure the first element in the array (which should be the only match), and assign it a value of button. That element handle can now be clicked.

I've been attempting to click a button in a pop-up with selenium, but I'm getting the following error:
object [HTMLDivElement] has no size and location
I have tried the normal way, with just click, since it is in the viewport and I am waiting for the page to fully load:
let pressCookieButton = await driver.findElement(By.xpath('//a[#class="btn-actiune btn-actiune--principal"]/..'))
await pressCookieButton.click();
But this does not work. It says
Element not interactible
Then, i tried to click using actions:
let pressCookieButton = await driver.findElement(By.xpath('//a[#class="btn-actiune btn-actiune--principal"]/..'))
const actions = driver.actions({ async: true });
await actions.click(pressCookieButton).perform();
But i get:
object [HTMLDivElement] has no size and location
The HTML that I am attempting to click is the following:
<div class="col-md-4 col-sm-4 col-xs-12">
Accept toate cookie-urile
</div>
Below is the full code:
const {Builder} = require('selenium-webdriver');
const {By} = require('selenium-webdriver');
(async function helloSelenium() {
let driver = await new Builder().forBrowser('chrome').build();
try{
await driver.get('https://www.imobiliare.ro/vanzare-apartamente/timisoara/matei-basarab/apartament-de-vanzare-3-camere-XCB61020C');
await driver.sleep(7000);
console.log("clicking")
let pressCookieButton = await driver.findElement(By.xpath('//a[#class="btn-actiune btn-actiune--principal"]/..'))
const actions = driver.actions({ async: true });
await actions.click(pressCookieButton).perform();
//findElement(By.className('btn-actiune btn-actiune--principal'));
await driver.sleep(10000);
await pressCookieButton.click();
}catch(error){
console.log(error)
await driver.sleep(5000);
// await driver.quit()
}
})();
As you can see from the GIF below, the xpath matches two elements and by using driver.findElement you are selecting the first one, while the correct one is the second.
So you should either use driver.findElements instead of driver.findElement and then select the second element, or use a selector targetting only the correct element, such as
driver.findElement(By.cssSelector('div[class*="vizibil-informare"] a[class*="principal"]'))
I need to check that a button is disabled (checking for a last page of a table). There are two with the same id (top and bottom of the table).
const nextPageButtons = await this.page.$$('button#_btnNext'); // nextPageButtons.length is 2, chekced via console.log
const nextPageButtonState = await nextPageButtons[0].isDisabled();
But when I do the above I get: elementHandle.isDisabled: Unable to adopt element handle from a different document.
Why doesn't this work?
So, this works:
const nextPageButtons = await this.page.$$('button#_btnNext');
const nextPageButton1 = await nextPageButtons[0];
const nextPageButton1State = await nextPageButtonsState.isDisabled();
I'm fairly new to Puppeteer and I'm trying to practice keep tracking of a selected item from Amazon. However, I'm facing a problem when I try to retrieve some results from the page.
The way I intended this automation to work is by following these steps:
New tab.
Go to the home page of Amazon.
Enter the given product name in the search element.
Press the enter key.
Return the product title and price.
Check this example below:
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({
headless: false,
});
const page = await browser.newPage();
await page.setRequestInterception(true);
page.on('request', (req) => { // don't load any fonts or images on my requests. To Boost the performance
if (req.resourceType() == 'font' /* || req.resourceType() == 'image' || req.resourceType() == 'stylesheet'*/) {
req.abort();
}
else {
req.continue(); {
}
}
});
const baseDomain = 'https://www.amazon.com';
await page.goto(`${baseDomain}/`, { waitUntil: "networkidle0" });
await page.click("#twotabsearchtextbox" ,{delay: 50})
await page.type("#twotabsearchtextbox", "Bose QuietComfort 35 II",{delay: 50});
await page.keyboard.press("Enter");
await page.waitForNavigation({
waitUntil: 'networkidle2',
});
let productTitle = await page.$$(".a-size-medium, .a-color-base, .a-text-normal")[43]; //varible that holds the title of the product
console.log(productTitle );
debugger;
})();
when I execute this code, I get in the console.log a value of undefined for the variable productTitle. I had a lot of trouble with scraping information from a page I navigate to. I used to do page.evaluate() and it only worked when I'm scraping from the page that I have told the browser to go to.
The first problem is on this line:
let productTitle = await page.$$(".a-size-medium, .a-color-base, .a-text-normal")[43];
// is equivalent to:
let productTitle = await (somePromise[43]);
// As you guessed it, a Promise does not have a property `43`,
// so I think you meant to do this instead:
let productTitle = (await page.$$(".a-size-medium, .a-color-base, .a-text-normal"))[43];
Once this is fixed, you don't get the title text, but a handle to the DOM element. So you can do:
let titleElem = (await page.$$(".a-size-medium, .a-color-base, .a-text-normal"))[43];
let productTitle = await titleElem.evaluate(node => node.innerText);
console.log(productTitle); // "Microphone"
However, I'm not sure that simply selecting the 43rd element will always get you the one you want, but if it isn't, that would be a topic for another question.
I'm trying to scrape this element: on this website.
My JS code:
const puppeteer = require("puppeteer");
const url = 'https://magicseaweed.com/Bore-Surf-Report/1886/'
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto(url);
const title = await page.$x('/html/body/div[1]/div[2]/div[2]/div/div[2]/div[2]/div[2]/div/div/div[1]/div/header/h3/div[1]/span[1]')
let text = await page.evaluate(res => res.textContext, title[0])
console.log(text) // UNDEFINED
text is undefined. What is the problem here? Thanks.
I think you need to fix 1 or 2 issues on your code.
textContent vs textContext
xpath
For the content you want the xpath should be:
const title = await page.$x('/html/body/div[1]/div[2]/div[2]/div/div[2]/div[2]/div[2]/div/div/div[1]/div/div[1]/div[1]/div/div[2]/ul[1]/li[1]/text()')
And to get the content of this:
const text = await page.evaluate(el => {
return el.textContent.trim()
}, title[0])
Notice you need send title[0] as an argument to the page function.
OR
if you don't need to use xpath, it seems you could get directly using class name to find the element:
const rating = await page.evaluate(() => {
return $('.rating.rating-large.clearfix > li.rating-text')[0].textContent.trim()
})
I've been looking for a good example of click events on every element of a certain class, but I can't seem to find one. In my app, I generate multiple bars in an svg with class .bar.
Is there a nice way to iterate through each bar in the selection and click it?
Here is my code so far (with the link to dev area removed):
const puppeteer = require('puppeteer');
(async () => {
//open browser, use headless to allowing viewing
const browser = await puppeteer.launch({headless: false, sloMo: 80});
const page = await browser.newPage();
//goto link
await page.goto('/link_to_test/');
//scraping automation goes here
await page.waitFor(5000);
let bars = await page.$$(".bar");
for(const idx in bars){
await bars[idx].click({delay:250});
}
// close browser
await browser.close();
})();
I've been looking for a way to select each bar from the $$(".bar") selection and click it but I cannot seem to find any documentation around it.
Update
I increased the page.waitFor to 5000 and removed the ElementHandle from the for loop. Code no longer throws any errors but it doesn't want to click anything.
Looks like this doesn't work for SVG elements yet https://github.com/GoogleChrome/puppeteer/issues/1769
Without seeing more code I am not sure whether this is the answer you need. This code selects all a.bars for a given ul and returns an array of all the hrefs. We then loop through the links and open each one in turn.
I think the missing bit of the jigsaw is that I am mapping the links to an array (see below ... links => links.map((a) => { return a.href }));
const puppeteer = require('puppeteer');
(async () => {
const html = `
<html>
<body>
<ul>
<li><a class="bar" href="https://www.google.com">Goolge</a></li>
<li><a class="bar" href="https://www.bing.com">Bing</a></li>
<li><a class="bar" href="https://duckduckgo.com">DuckDuckGo</a></li>
</ul>
</body>
</html>`;
const browser = await puppeteer.launch({ headless:false});
const page = await browser.newPage();
await page.goto(`data:text/html,${html}`);
const data = await page.$$eval('ul li a.bar', links =>
links.map((a) => { return a.href }));
//You will now have an array of hrefs
for (const i in data) {
console.log("Opening", data[i]);
await page.goto(data[i]);
}
await browser.close();
})();
