描述

A dataset of 300 records in a table using ui-sortable has a 3-4 second delay after the item being dragged is dropped that appears to be related to sorting the newly ordered data that prevents any actions from occurring until complete, which includes any further dragging and even scrolling the page.

研究方向
Investigate the drop handler in ui sortable.js to understand the sorting logic that causes a 3-4 second delay with 300 records. Profile the JavaScript execution to identify bottlenecks, possibly in the DOM manipulation or model synchronization. Check if the issue is related to the digest cycle in AngularJS. Consider optimizing the sorting by using a more efficient algorithm or deferring the sort operation.
