jscript vs javascript

In the many operators of JScript, three logical operators are provided 、 ||And !Oh?! is available in advanced languages. According to our normal understanding of the logical operation, the result of the logical operation is ture or false. But the logical operation of JScript is not entirely defined here, only the! operator always returns true| false, while | | and operations compared to the fun.

1. JScript is a loosely coupled object-based scripting language. The so-called loosely coupled language is the type of declarative object that does not need to be displayed. In many cases, the object type can be automatically converted to what we need when necessary. 2. We recommend that you always declare the object before using the object. If the object is not initialized in the VaR statement, the automatic value is:Undefined.The VaR keyword is not

In the article "How to use this keyword in JavaScript", I have cited the 8 kinds of this keyword in JavaScript and JScript. This does not find that there are also two kinds of this keyword used at the time did not say, now added. And by using the first this keyword, we can better understand the nature of JavaScript as

Http://code.google.com/p/naturaljs/ accessOn Google code, you can get the source code of the JScript rapid development framework EDK. I believe that the first step for many people to learn web is to connect to data, and the encapsulation process is also like this. It seems unnecessary to talk about connecting to the database. It is only a few steps, but it is still necessary to talk about it. Therefore, before introducing the Code, review the general

The method for reading and writing binary files by jscript. This document describes how jscript reads and writes binary files. Share it with you for your reference. The specific implementation method is as follows: var bin = new Array(256);for(var i=0;i Example: var crFolder = 'C:/Temp/cr'var bf1=new BinaryFile(crFolder+"/PCDV0026.JPG");var bf2=new BinaryFile(crFolder+"/PCDV0026_.JPG");bf2.WriteAll(bf1.Read

The inheritance of JScript can be implemented in two ways: the prototype attribute of the object and the call function. The first method also applies to Javascript, and the second method only applies to JScript. The following example shows the inheritance implemented using prototype: var person = function (){ This. Name = "person "; } VaR _ p = person. Prototyp

To read XML files using JScript, you must consider multiple versions of the msxml component. A safe way is to list all versions. The content of the xml file is as follows: [Html] The JScript used to read the xml file is as follows: [Javascript]Main ();Function main (){Var xmlDoc = null;Var signatures = ["Msxml2.DOMDocument. 6.0 ","Msxml2.DOMDocument. 5.0 ","Msx

Among the many operators in JScript, three logical operators are provided.,|And!Oh ?! Is provided in advanced languages. According to our normal understanding of logical operations, the logical operation result should be true or false. However, the logic operations of JScript are not exactly defined in this way. Only! The true | false operator is always returned, and | is more fun.JScript defines true or fa

Statements in Jscript are generally run in the write order. This kind of operation is called sequential operation, which is the default direction of the Program Stream. Different from sequential running, another operation switches the program flow to another part of the script. That is, run another statement instead of the next statement in sequence. To make the script available, the conversion of this control must be performed logically. The conversi

I don't even remember when I saw the JScript syntax tutorial. It means it is completely legal to ignore the VaR keyword when declaring a variable. At that time, because JavaScript was thought to be the loosely-typed language, VAR may be a decoration. However, facts often prove that the result is unreliable. Let's take a look at the results of the following examples to find out the problem: No.1 [

continue. Obviously, this will never reach a termination point. Therefore, you should be careful when designing recursive functions. If you suspect that there is an infinite recursion possibility, you can let the function record the number of times it calls itself. If the function is called too many times, it exits automatically even if you have determined how many times it should be called. The following is still a factorial function, which is written in J
