default value is true. When the sending parameter is in the traditional format, set it to false. Showav is a callback function. If we debug it on the server, we can see that the server needs to receive callback parameters. During debugging, we will find that it is a value similar to jsonxxxxxx, in jquery, it is clearly stated that this value represents the showav function in this article, In this way, check the server'sCodeThe server code is actually showav ('abcdef'), that is, the followin

, it is a good idea to modify the number of files that each process can open by using Ulimit-n XX, which defaults to 1024.Ulimit-n 4096 increases the number of files that can be opened per process to 4096, and defaults to 1024Some important settings for other suggestions that are set to unrestricted (unlimited) are:Length of data segment: Ulimit-d UnlimitedMaximum memory size: Ulimit-m UnlimitedStack size: Ulimit-s UnlimitedCPU Time: Ulimit-t UnlimitedVirtual Memory: Ulimit-v Unlimited 　　Tempora
