描述

$scope.gridOptions = { infiniteScrollRowsFromEnd: 100 }

It seems as though until a user stops scrolling the "needLoadMoreData" event/function does not get called and is not accounting for the infiniteScrollRowsFromEnd.
The idea behind infinite scrolling is that you can start the request for more data before the user reaches the end of the grid and it would be awesome if the grid would start the request even if the user is still scrolling and would subsequently concat the response data to the end without messing up the scroll position (even though I am using saveScrollPercentage).

研究方向
Investigate the infinite scroll implementation in UI Grid, specifically the scroll event handler that triggers needLoadMoreData. Look at the grid's code for handling `infiniteScrollRowsFromEnd` and verify if it only checks after scrolling stops or at bottom. Check for any related commits or PRs that may have addressed this, e.g., PRs around infinite scrolling in the repository's history. Consider testing with a minimal Angular app to reproduce the behavior.
