如何使用 Puppeteer 設置間隔以運行一定的時間？

Question

我想設置一個間隔，所以代碼每秒更新一次，但只有 2 分鍾。

我不確定如何設置。

const puppeteer = require('puppeteer');
(async () => {
    let game = 'https://lichess.org/hj4DgCNN9BKG';
    let browser = await puppeteer.launch({ headless: false });
    let page = await browser.newPage();
    await page.goto(game, { waitUntil: 'networkidle2' });
    let data = await page.evaluate(() => {
    let time = document.querySelector('div[class="time"]').innerText;
        return {                time
        };
    });
        console.log(data);
})();

你可以嘗試這樣的事情：

const puppeteer = require('puppeteer');
(async () => {
    let game = 'https://lichess.org/hj4DgCNN9BKG';
    let browser = await puppeteer.launch({ headless: false });
    let page = await browser.newPage();
    await page.goto(game, { waitUntil: 'networkidle2' });

    const end = Date.now() + 120000;

    while (Date.now() < end) {
      let data = await page.evaluate(() => {
        let time = document.querySelector('div[class="time"]').innerText;
        return { time };
      });
      console.log(data);
      await page.waitForTimeout(1000);
    }
})();
