The uniapp page cannot trigger the onReachBottom event

question

Pulling up to load the next page of data or list cannot trigger the onReachBottom event

 reason:

1. Using scroll-view results in no scrolling at the page level, so the bottoming event will not be triggered. 

2. We often encounter when the list is found to be drop-down; the onReachBottom event cannot be triggered. It turns out that there is a problem with the nesting of the list content; the onReachBottom event cannot be triggered. If the list content is a component, there is no need to wrap it with another outer layer.
