Is it true that you can be blocked and deleted on WeChat and permanently unable to be added?
Apr 08, 2024 am 11:41 AM
1. First of all, it is false to block and delete someone permanently and not add them permanently. If you want to add the other party after you have blocked them and deleted them, you only need the other party's consent. 2. If a user blocks someone, the other party will not be able to send messages to the user, view the user's circle of friends, or make calls with the user. 3. Blocking does not mean deleting the other party from the user's WeChat contact list. 4. If the user deletes the other party from the user's WeChat contact list after blocking them, there is no way to recover after deletion. 5. If the user wants to add the other party as a friend again, the other party needs to agree and add the user again.

This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.
