Hi everyone, I’m using Puppeteer to load a web page with page.goto(url) and then clicking to switch to another page. On the new page I try to identify a purchasing button using this snippet:
const purchaseElem = await page.waitForSelector('#purchase-button');
However, I always receive a pending promise and can’t interact with the button. It appears the element might not be loaded in time. What can I do to make sure the button is ready for use? Thanks a lot!
I faced a similar issue when working with dynamic pages that load elements asynchronously. In my case, the purchase button was added to the DOM only after certain delayed JavaScript executions, which meant that device timing was crucial. I eventually solved the problem by combining a more robust wait strategy: when navigating, I specified options like waitUntil: ‘networkidle0’ to ensure the network was quiet. Additionally, I increased the timeout on waitForSelector. Tweaking these settings helped me align the script execution with the page’s actual load state.
After encountering a similar problem, I discovered that explicit waiting for the entire network to settle made a significant difference. I refined my approach by verifying that the page had indeed finished loading before attempting to interact with the purchasing button. For example, I transitioned from solely relying on waitForSelector to also waiting for key navigation events with extended timeouts, which ensured that delayed scripts had time to execute. I even added brief pauses using waitForTimeout in specific cases. This method helped me synchronize the script with the page’s dynamic content, making the interaction more reliable.
hey, i had simlar issues and ended up using waitForFunction to check for element readiness. it works better sometimes than just waiting for selectors. a small custom wait ensured my page scripts were done loading before i tried to click the btn.
