In Javascript, the mode separation dialog box and the non-mode dialog box are displayed. The following describes the usage of the two. In Javascript, the mode separation dialog box and the non-mode dialog box are displayed, in fact, the difference between the two is whether the user can work elsewhere on the same page

When developing large systems, the following situations often occur:
I have A part of the basic data. The class classA is read from database A, and many other functions are operated based on this basic data. Now, I want to change the data from database A to another data source. At this time, it is troublesome

I haven't written any articles for more than half a month. It's mainly because there are a lot of messy things in my senior high school, hitting the wall for a job. We also blame ourselves for the poor strength, but also for the lack of practical experience, which is difficult to attract HR interest. So I am still making
The syntax of JS is very flexible. There are several different methods for creating simple objects. These too flexible places are sometimes confusing. Let's take a look at several common methods for creating objects in JS today. In the previous article, we introduced the javascript object-oriented basics, this article continues to learn about javascript object-oriented in depth. JS syntax is very flexible, and there are several different methods for simple object creation. These too flexible pla

When we use the win10 system, we may need to enter the Security Mode for virus detection or something, so how does Win10 enter the security mode? It is usually complicated to enter the secur
Three basic design patterns (three of the most common in all object-oriented design patterns):① Factory mode : Use factory methods or classes to generate objects instead of directly new in codeCreate a new factory.php under the Common directory:phpnamespace Common; class factory{ staticfunction createdatabase () { //$db = new \common\database; $db New Database; return $db ; }}index.php:PHP Define // defining a root directo

There is a barbecue stall on the side of the road, and a boss is responsible for barbecue food for the guests. If there are few guests, the boss can accurately remember everyone's requirements. As the number of guests increases, the number of requirements increases, making it difficult for the bo
Java Singleton mode and dual-instance mode, java mode
Today, my friend asked me to give a question. I have never heard of the dual-sample mode. It is a singleton mode and a multi-sample mode,
I don't know when to use the dual-samp
CTR Mode is a stream cipher that generates a key stream by encrypting successive accumulated counters, and in CTR mode, each packet corresponds to a successive cumulative counter, and the key stream is generated by encrypting the counter. The final cipher packet is obtained by XOR the bit sequence encrypted by the counter and the plaintext packet, as shown in:The method for generating the counter is as foll
Head First design mode adapter mode and appearance modeObjective:Before we've talked about decorator patterns, wrapping objects and giving new responsibilities, this chapter also wraps objects, just to make them look less like themselves and something else. This allows the interface of the class to be transformed into the desired interface in the design to implement the same interface, and another pattern w
Bridge Bridging Mode (structural mode)Abstraction and implementationAbstractions should not be dependent on implementation details, and implementation details should be dependent on abstraction.Abstract b stability, implementation details B changeThe problem is that if abstract B is inherently unstable and likely to change because of its inherent causes, what happens?For exampleIf we need to develop a tank
In fact, this three C + + design pattern has been learning for a long time, only to remember tonight to write these three design patterns, why use C + + design patterns? For example, you've been driving, just driving, upside down, turning, these are all basic, but you're not very good at driving, and not cool. Drift, just like the design patterns in C + +, you learn C + + based on a skilled application of new skills, can make your car more open.Why use a simple factory model, remember the last t

Note: A factory class is created to create the implementation class for the same interface.
But JavaScript seems to have no interface, so we should remove the interface layer. Of course, the member variables in the implementation class he
