In the first chapter, we use constructors and prototypes to implement classes and inheritance in the world of JavaScript, but there are many problems. In this chapter we will analyze each of these issues and give a solution.Note: The implementation of Jclass in this chapter refers to the simple JavaScript inheritance approach.First, let's review the example presented in the first chapter:Fixed pointing error for constructorFrom the description of constructor in the previous article, we know that

side is allowed to listen for an unused, arbitrary port on this machine, such as 1234, while directing data from Port 1234 to the 80 port on the remote (b-Machine) (note, 80 ports, firewall allowed to pass), Then a server on the B-machine, also hooked on port 80, also directs 80 ports from the client forward to the local Telnet service port 23, so OK. Now on the a machine Telnet native port

Create an exception yourself Native Exception, abbreviated as NE, is the most common anomaly that occurs in C + + code.When we write code, some common operations can cause NE, such as null pointer assignment, array access, and so on, now I add a simple exception in the code: TEST.C: 1 #include Android.mk 1 Local_path: = $ (call My-dir) 2 include $ (clear_vars) 3 4 local_cflags + =-g3-o0 5 6 Local_src_file S: = test.c 7 8 Local_module: = Test 9 local_multilib: = All

Db_params is used to set the connection parameters for the database, passing in the fourth parameter of the PDO instantiation. The following is a typical database global setting: The code is as follows: ' Db_type ' => ' mysql ',//database type ' Db_host ' => ' 192.168.1.10 ',//server address ' Db_name ' => ' thinkphp ',//database name ' Db_user ' => ' root ',//username

information must have the same number and the same data type, or else an error will occur.4.1 Number of columns of statisticsWhen the error message is not masked, the number of columns that are currently being tried is correct when the number of columns to get is only required to use a different number of fields each time the union select injection occurs, and when the error message is changed from column number mismatch to column type mismatch. However, in blind conditions, this method also lo

Create User: mysql> INSERT INTO Mysql.user (Host,user,password) VALUES ("localhost", "User", Password ("1234")); This creates a user with the username: 1234. Note: "localhost" here means that the user can only log on locally and cannot telnet to another machine. If you want to telnet, change "localhost" to "%", which means you can log on on any computer. You can also specify that a machine can log on remot
