Problems that arise:
When deleting a piece of data, a prompt will be given when finished: toastr.info("Deleted!")
When you continue to delete, two toastr will appear,
If you delete it again, there will be 3 toastrs, in short, the more points, the more.
I don't know if you have encountered such a situation.
The reason may be the delete method written in the modal box,
Solution: Move the delete method out of the pop-up modal box and write it outside
No solution, you can leave a message
