When we are browsing multiple pages at the same time, most people are likely to encounter a Web page is mistakenly closed, if only mistakenly closed a Web page, can also be found in the history of the log back, if the wrong operation closed the entire IE browser window, and then through the history of a closed Web page

JS Closed PackageWrite before the closure:context is the smallest set of data required for a program to run. We can understand the context from context switch, in a multi-process or multi-threaded environment, the task switch first interrupts the current task, the computing resources to the next task. Because the previous task will be restored later, the time to save the scene, that is, the context of the current task, can also be called the environme

In this chapter, we will explain part 1 of the Five Principles of S.O.L. I. D, implementation of the JavaScript language, and the principle of OCP (TheOpenClosedPrinciple ).

The open-closed principle (open-closed principle) is the cornerstone of object-oriented reusable design (Object Oriented Design or OOD. Other design principles (the Lee principle of substitution, the principle of dependency inversion, the principle of synthesis/aggregation reuse, the principle of Demeter, and the principle of interface isolation) are the means and tools for implementing the "open-

Under what circumstances can not write PHP's closed tag "?>", do not write PHP In some PHP projects we often see that some PHP files in the code is only the start tag, but not the end tag, then under what circumstances can not write the end tag, and under what circumstances must be written? Let's take a look at 2 examples first: The following code will work: The following code will error: Abc Cause Analysis:The former is pure PHP code, you can not w

Under what circumstances can I leave the PHP closed tag "?> ", Leave php empty In some PHP projects, we often see that the code in some PHP files only has the start tag but not the end tag. Under what circumstances can this end tag be left blank, under what circumstances must I write? Let's look at two examples: The following code runs properly: The following code reports an error: Cause analysis:The former is a pure php code. You can neither write

9th OCP: Open-closed principleSoftware entities (classes, modules, functions, and so on) should be extensible, but not modifiable.9.1 OCP OverviewModules designed to follow the open-closed principle have two main features:(1) is open for extensions (open for extension). This means that the behavior of the module can be extended. When the requirements of the application change, we can extend the module to th

Open-closed Principle It means that software entities (classes, modules, functions, and so on) can be expanded, but cannot be modified.This principle actually has two features:Open for expansion(Open for extension) ", the other is to say"Changes are closed.(Closed for modification )"What kind of design can we face the changes in requirements, but it can be relati

Definition: A software entity, such as a class, module, or function, should be open to extensions and closed to modifications. Problem:During the software life cycle, errors may be introduced to the Old Code when the original code of the software needs to be modified due to changes, upgrades, maintenance, and other reasons, it may also cause us to have to refactor the entire function and re-test the original code. Solution:When the software needs to c

Origin: What kind of design can we face the changes in requirements, but it can be relatively stable, so that the system can continue to launch new versions after the first version? The well-known development-closed principle (the open-closed princle) proposed by Bertrand Meyer in 1988 provides us with guidance. The modules designed according to the open-closed

The object-oriented principle consists of seven principles: 1. Principle of Open/closed 2. Principle of dependency inversion 3. Principle of single responsibility 4. Principle of replacement by Lee's family 5. Principle of compound reuse 6. Principle of prompt 7. Principle of interface isolation These principles do not exist in isolation. They are mutually dependent and complementary. 1. Definition of the open/

Software entities (classes, modules, functions, etc.) should be extensible, but cannot be modified. It is open for expansion and closed for change. No matter how close the module is, there will be some changes that cannot be closed to it. Since it cannot be completely closed, the designer must choose which change should be

Open and closed principle: software entities (classes, modules, functions, and so on) should be extensible, but cannot be modified. In fact, this principle has two features: openness for expansion, and closed for changes. What kind of design will be able to maintain relative stability in the face of demand changes, so that the system can continuously launch new versions after the first version? The open and

It has been closed for several weeks and has been with the outsourced Microsoft Project Team. It is lucky that more than half of the time it takes to come to the company out of the closed project status, because closed projects are usually important and mysterious (well, or because there is no place to sit in the office area,=, = Bbb). People's work emphasize

function is called exactly?Look at the original question, now know that the program has two fun functions (the first and the third is the same), then the next question is to figure out what the fun function he was running?function Fun (n,o) { console.log (o) return { fun:function (m) { return fun (M,n);}} ;} var a = fun (0); A.fun (1); A.fun (2); A.fun (3);//undefined,?,?,? var b = Fun (0). Fun (1). Fun (2). Fun (3),//undefined,?,?,? var c = Fun (0). Fun (1); C.fun (2); C.fun (3

In the daily operation of the browser, it is inevitable that the label will be closed incorrectly. The official Chrome Blog shares three techniques for recovering a closed tag, which you might use to recover the next time you encounter a false shutdown:1, you can find in the new tab at the bottom of the "Recently closed tab page", this place will have your recent

Chrome Google browser has closed the page? The first method: shortcut keys. Many people do not know what the Chrome browser undo closes the page shortcut key is what, actually this is a key combination, namely crtl+shift+t. For friends who are accustomed to using shortcuts, this is the quickest way to restore a chrome-closed web page. The second method Select the

String when resolving the IIF problem, in order to determine whether the IIF statement is legitimate, and find the conditions therein, return the value True and return the value false. It's not natural. A general function module is written to solve a string of words in the closed symbolic form. such as "(...)", "[...]" , reader can also set a closed symbol or string, but it must be symmetric, such as "AVB"

whole, it is a unity of mutual complementarity and integration, and also has their own independence. Therefore, in engineering design and installation and construction, coordination must be carried out with the design and construction units of the house building and other facilities, and comprehensive consideration and proper handling methods should be taken to solve the problem in a timely manner, to ensure normal use. In addition to communication networks, computer networks, and building auto
