return-1; ["AA", ' BB '].indexof (' BB '); 1 The indexOf () function always returns the index of the first element with the same parameter, and another function similar to that is the LastIndexOf () method, which returns the index of the last element in the same element, or 1 if it is not found. such as: ["AA", ' BB ', ' cc ', ' AA '].lastindexof (' AA '); 3 ["AA", ' BB ', ' cc ', ' AA '].indexof (' AA '); 0 4.

Using an SSH client (such as: Putty) to connect to a Linux server may wait 10-30 seconds to prompt for a password. Seriously affect work efficiency. Logon is slow, log on after the normal speed, this situation is mainly for two possible reasons: 1. DNS Reverse resolution problem OpenSSH when the user log in to authenticate the IP, it is based on the user's IP using reverse DNS to find the host name, and then use DNS to find the IP address, and finally match the IP of the login is legitimate.
