Javascript for scraping video from Kuaishou

 When developing a Chrome extension to automatically extract and download videos from platforms like KuaiShou, one of the biggest challenges is dealing with unresponsive or invalid video cards.

Sometimes, a video card is clicked, but no video loads. This results in failed downloads and an incomplete automation cycle.

In this article, we’ll explain how to handle this edge case by adding a retry mechanism that reloads the card and attempts to extract the video again—all without refreshing the entire page.
