To understand the definition and execution of JavaScript functions, you need to know these important concepts first, and now you can understand them later!the execution environment of the function (Excution context), the active object (call object), scope (scope), scope chain (scope chain). Next, let's take this function as an example to analyze:Steps:1. Set the scope chainWhen you define function A, the JS interpreter willScope Chain (scope chain)Set

Like to read some Open-source project source, always will find that the great God's code always have some short and efficient macro definition, click to see, find obscure, not to mention learning, sometimes understanding is a difficult, but the macro definition itself is not so difficult, But write a good macro of course still need rich experience and technology, then say a macro

In Java, an array is considered an object When you define an array, there are two definitions: int[] A and int a[]; the second is a C + + array-defined method, with the first definition of Java recommendations. The general principle: any object must be initialized before being called. definition of 11-D arrays Defines a one-dimensional array that contains three elements //Method 1, first the new object, an

css| Project This tutorial mainly explains the definition of the style of common tags Li {list-style-image:url (images/disc.gif);} This style definition for Li is to use a picture for a list item instead of a small dot that is displayed.

Let's start with an introduction to creating and managing tables and views

Simple introduction of physical and pinIn the development of the time will often use the serial interface, the general 9-pin serial interface is mostly. For example, as seen in:The male female head is used in the packaging of the connecting wire. However, a 90-degree angled pin package is used for the Development Board. For example, with:Each pin is defined as:2. Connection of male female head to MAX232When the male head is connected with the MAX2

"Transcoding" for each family may not be the same, but the logic is the same, I am sharing today is another Pat cloud on the narrowband high-definition transcoding, close to the "transcoding", more basic, theoretical knowledge will be relatively more. Share content mainly divided into two pieces, the first is to introduce what is narrowband high-definition transcoding, the second is to introduce and pat the

#defineThe command #define defines an identifier and a string. Each time the identifier is encountered in the source program, it is substituted with a defined string. The ANSI standard defines an identifier as a macro name and replaces the process with a macro substitution. The general form of the command is: #define Identifier string Attention:1. The statement does not have a semicolon. There can be any space between the identifier and the string, which, once started, ends only wi

Definition of structureThe general form of defining a structure is:struct structure name{Member table columns}A member table consists of several members, each of which is an integral part of the structure.A type description must also be made for each member.For example: Copy Code code as follows: struct STU { int num; Char name[20]; int age; } description of struct type variableA struct

This article details the JavaScript of various common function definition methods, share for everyone to reference. The specific analysis is as follows: First take a look at four of the most common function definitions of javascript: Functions defined with function constructors, the code is as follows: var multiply = new Function (' x ', ' y ', ' return x * y; '); function declaration, this is also the most common one: function

Like a function template, using a class template enables a user to define a pattern for a class, allowing some data members in the class, arguments to some member functions, and return values of some member functions to take any type. A class template is an abstraction of a class that is different from a group of member data types only. Programmers can greatly improve the efficiency of programming by creating a class template for the entire family of classes, giving a set of program code to gene

Recently in busy live555 project; Honestly, this is the first big project I've done. Although it was the first time I had done such a big project for such a long time, I felt that I had made no progress in this year; adding a global variable wasted my half a day of force. No more nonsense, cut to the chase. Global variables, the earliest I read the C primer Plus is supposed to be called an outsider variable. is always declared with the keyword extern in a header file, the declared variable can

(i) Symbolic constants A macro definition is a substitution policy in C that uses a preprocessing command #define equate a string of (verbose) text with a name (called a macro), and then you can use the macro in bulk in the source code. In the preprocessing phase, replace the macros in the source code with the original text. For example, in the source code: #define PI 3.14Then in the next code, you need to write 3.14 of the place can be directly r

If you haven't contacted a dynamic language, it will be a magical and weird feeling to understand JavaScript in a compiled language, because the things that are often impossible in consciousness happen, and even feel unreasonable. If you're learning JavaScript in a free and changing language, this is the way you feel. , then from the beginning, please put down your "prejudice", because this is absolutely a new continent for you. Well, not to everyone chit chat when, to get to the bottom of it, l
