Suggestions for dpmap modification:
1. The label icon is changed from 32x32 to 16x16. If possible, useCodeColor.
2. sendrequest. js separates the functions used by the respective pages to avoid loading irrelevant code and improve efficiency.
3. Rewrite the Ajax query annotation code. The current query efficiency is too low, and the query method is loaded with arrays and then cyclically traversed. The loop consumes too much time and execution efficiency is very low. This is the most troublesome. You may need to rewrite the entire core code. However, sooner or later, we need to change the efficient query method.
4. Add a scaling factor to display the annotation points after the corresponding multiples of the query results. This prevents all query results from being displayed at the same level multiple at the same time, reducing the display efficiency.
