静态页面无限滚动它是如何工作的？

Question

中等https://medium.freecodecamp.org/上的这个页面使用无限滚动，但是在查看源代码时，html 在那里，所以它不使用 ajax 还是我弄错了？

Answer 1

Open the network panel in your inspector and watch the requests roll in as you scroll down. It's just getting jpg images so it's likely that the html is already there and the scroll action causes an ansync request for the image and javascript plugs it into the appropriate divs.
