To wait for elements to load in Puppeteer, you can use the following methods:
- Using waitUntil option: You can use the waitUntil option in the page.goto() method to wait for specific events before proceeding. For example, you can wait until the network is idle or until all resources have finished loading.
await page.goto('https://example.com', { waitUntil: 'networkidle0' });
- Using waitForSelector: You can use the waitForSelector method to wait for a specific element to appear in the page before continuing.
await page.waitForSelector('#elementId');
- Using waitForTimeout: You can use the waitForTimeout method to wait for a specific amount of time before proceeding.
await page.waitForTimeout(2000); // wait for 2 seconds
- Using waitForFunction: You can use the waitForFunction method to wait until a specific JavaScript function returns true.
await page.waitForFunction(() => document.querySelector('#elementId'));
By using these methods, you can ensure that the elements you are looking for have loaded before interacting with them in Puppeteer.
