Using Puppeteer with NodeJS, how can I interact with a non-first element when several share the same identifier? For example:
const results = await page.evaluate(() => Array.from(document.querySelectorAll('.data-active')).map(elem => elem.innerText));
console.log(results[1]);
I have dealt with this scenario on a project where determining the correct element in a list was crucial. What I ended up doing was ensuring that I had a robust way of indexing the NodeList created by querySelectorAll. Since the query returns all matched elements, you can directly access the element at any given index with the array notation. In my case, I sometimes also cross-referenced the DOM structure to ensure that the correct element was being selected as the list order might change dynamically. This approach helped me avoid unexpected errors at runtime.
In my experience working with Puppeteer, using page.$$ to fetch elements and then indexing into the resulting array is a straightforward approach. I have sometimes experienced issues when the DOM updates dynamically, so it is important to verify that the elements you are targeting remain in the expected order. In situations where the DOM might change, consider waiting for the element or using additional attributes to ensure you’re interacting with the correct item. This method has proven effective in maintaining control over element selection in my projects.
