Description: gets the return value of FunctionPage. aspx. If the return value is 1, it indicates that synchronization loading is completed.
Case 1: in ie, the synchronization data loading is completed after the synchronous call is completed. No prompts are displayed during data loading, and ie is suspended.
Case 2: ff is normal. The execution sequence is as follows: Data Loading in progress-> ajax request execution-> Data Loading completed.
Conclusion: The synchronization mode in ie will lead to the assumption that ie is dead. This user experience is quite uncomfortable. I don't know if there is any better solution, so I will implement logic in asynchronous mode for the moment.
