Copy codeThe Code is as follows: Let's talk about the phrase T. constructor = this in the above Code. I feel that this sentence has no practical effect,Itself T. constructor should be Funtion. Why should we set it as a Funtion instance,Copy codeThe Code is as follows: In the above code, I added one sentence, corrected that the subclass constructor still points to the subclass function, but the back-to-back of the prototype chain of the object cannot reach the parent class prototype. The solution

If you are puzzled by the actual operations on Python strings, you can use the following articles to better understand them, the following describes the skills related to the practical application of Python strings. The following is a detailed description of the article. Search and replace Python strings: *S.find(substr,[start,[end]]) Returns the number of the first letter of substr in S. If S does not contain substr,-1 is returned. The functi

The Python timer is a commonly used computer language in computers. In its extensive practical application operations, it will involve the actual application of Lock. If you are interested in the practical application of Lock in the Python timer, you can get a deeper understanding through our articles. Practical application of Lock in Python Timer The Lock/RLock keyword is similar to the C # lock keyword. The difference is that Lock/RLock only needs t

declaration, then execute the base class constructor, Then initialize the subclass normal variable and the ordinary code block in the order of declaration, and finally execute the subclass constructor.The order of execution in this test is to initialize the static variable first, which needs to be loaded before executing the main () method. Then the main method, if new, initializes the basic member variables of the object class (non-Methods), including building blocks of code, which are execute

Detailed explanation of several ajax request methods that may be encountered in actual practice. Preface Recently, I was working on a function page for Speed Measurement for a single node. The logic of speed measurement is that when the upload speed is measured, the frontend transmits 5 MB of data to the server to record the time when data is uploaded and returned, during the download speed test, 1 MB of data is downloaded from the server, recording t

with the row, it no longer searches Not exists MySQLexplain optimizes left join. Once it finds a row that matches the left join standard, it no longer searches. Range checked for each The Record (index map: #) does not find the desired index. Therefore, for each row combination in the preceding table, MySQL checks which index is used and uses it to return rows from the table. This is one of the slowest connections using indexes. When Using filesort sees this, the query needs to be optimized

framework. NET a lot of new knowledge points are strung up, such as using spring.net to remove the coupling between the framework layer and layer, T4 template to quickly generate entity classes and application classes, the EF5.0 context into the thread to improve operational data efficiency, controller and view layer separation, etc. This framework provides us with a solid and efficient bottom-up project, from which we can move our attention to the front-end and focus on our customers ' busines

The following articles mainly introduce the disadvantages of MySQL indexes and the actual operations of MySQL indexes, which deserves our attention, we may not know that using indexes too much will cause abuse. Therefore, MySQL indexes also have their disadvantages:Although the index greatly improves the query speed, it also reduces the speed of updating the table, such as performing INSERT, UPDATE, and DELETE operations on the table. When updating a

How to use Huawei switches to implement DHCP + VRRP + MSTP (actual case) I. Topology Description: This is a topology of a real project, but lacks some security devices, however, it is sufficient for us to use a simulator to implement its important functions. The project uses HuaWei AR2240 as the core route, two HuaWei S9300 as the core switch, and the other is the access switch. The specific configuration is as follows. II. Specific configuration 1. C

size is the size of the pointer.Note: About the size of 64-bit systems and 32-bit systemsIt can be determined that the 32-bit system has a pointer size of 32 bits, which is 4 bytes.A 64-bit system has a pointer size of 64 bits or 8 bytes.However, for types of type long double, the 32-bit 64-bit is different depending on the system size. No set criteriaHowever, if int32_t or int64_t are present, these are types defined for portability, representing 32-bit int and 64-bit int with fixed 32-bit and

Recently encountered a problem with egg pain. In the external input data, the text gets to the data, and then stored in an array object inside. I use the array to do the loop judgment. Each time the next one comes in, it loops through the array before it, to see if it has the same value. But sometimes it can be compared for the first time. However, after 3 elements have been added. To scan the value of the first one. The first value will appear, or it can be added to the array. This question is

This article mainly introduces the MySQL5 trigger. Every time I demonstrate the actual code, I will use MySQL (the best combination with PHP) the code displayed on the screen of the client is adjusted, mainly by changing the font to Courier, making them look different from the common text so that you can differentiate the program code and body ). Here is an example of the MySQL5 trigger Tutorial: MySQL (best combination with PHP)> drop function f; Qu
