[英]Puppeteer: No node found for selector - Login Modal in iframe
我要go到登錄頁面,點擊用戶名,輸入用戶名。
這是我到目前為止所擁有的:
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({ headless: false, slowMo: 200 });
const page = await browser.newPage();
await page.goto('https://fantasy.espn.com/basketball/team');
await page.waitFor(2000);
await page.click('#did-ui-view > div > section > section > form > section > div:nth-child(1) > div > label > span.input-wrapper > input');
await page.waitFor(2000);
await page.type('#did-ui-view > div > section > section > form > section > div:nth-child(1) > div > label > span.input-wrapper > input', 'hello', { delay: 100 });
await browser.close()
})();
我繼續收到此錯誤:
Error: No node found for selector: #did-ui-view > div > section > section > form > section > div:nth-child(1) > div > label > span.input-wrapper > input
我不明白; 當我這樣做時,控制台中的document.querySelector
會返回輸入; 為什么找不到那個節點?
該元素在 iframe 中。所以首先您需要獲取框架,然后 select 來自該框架的元素。 你通常會這樣做:
let iframeHandle = await page.$('#disneyid-iframe');
let frame = await iframeHandle.contentFrame();
let inputElement = await frame.waitForSelector('#did-ui-view > div > section > section > form > section > div:nth-child(1) > div > label > span.input-wrapper > input')
await inputElement.type('hello', { delay: 100 });
但是,進程外框架存在問題,因此您需要使用--disable-features=site-per-process
啟動 chromium。 以下應該工作:
const browser = await puppeteer.launch({headless: false, args: ['--disable-features=site-per-process']});
const page = await browser.newPage();
await page.goto('https://fantasy.espn.com/basketball/team', {waitUntil: ['load', 'domcontentloaded','networkidle0']});
await page.waitFor(5000);
let iframeHandle = await page.$('#disneyid-iframe');
let frame = await iframeHandle.contentFrame();
let inputElement = await frame.waitForSelector('#did-ui-view > div > section > section > form > section > div:nth-child(1) > div > label > span.input-wrapper > input')
await inputElement.type('hello', { delay: 100 });
