Methods for uniapp to implement scrolling loading: 1. Use the "onReachBottom(){console.log("...")}" method; 2. Use "
..." method.
uniapp implements scrolling to the bottom to load more data
If the amount of data is very large, batch loading of data is an optimization method, so how to implement it?onReachBottom
Life cycle of uniapponReachBottom The event when the page scrolls to the bottom (not scroll-view to the bottom), often used to pull up and load the next page of data. For example Using scroll-view results in no scrolling at the page level, so the bottom event will not be triggered

onReachBottom(){ console.log("我已经滚动到底部了")}This will be triggered when the page scrolls to the bottom Event
