Like the previous Essay, Leavord also uses jquery paging. If you want to learn jquery paging, downloading this code is also a good choice. Leavord also has built-in IP real address query. As for the verification code, I think if you put it up, users will not want to leave messages after seeing it. This can be upgraded later based on needs. Everything that should be commented in the source code is commented, it’s up to you whether you understand it or not. If you have any questions, feel free to email me so I can write the next version. Next, we are going to write a simple and practical editor Textbox, so stay tuned. ps: The source code can be changed at will, but the risks incurred are borne by yourself. ^_^
