Obviously, we can get a conclusion from the test results: in a performance-oriented context, mixing multiple scripting languages is generally meaningless. If you want to consider the difference in the results of a two-time pattern-matching test, you should also see that each iteration creates an instance of the RegExp object.
There are two other important conclusions we can draw from these test results. First, if a language itself supports a feature, it is always quicker t
The concept of collections is common in Windows scripts, especially in WMI-related scripts, where collection operations are generally encountered.
The way to iterate through the collection in VBScript is simple, for Each loop can achieve the purpose. However, in JScript

IE's ECMAScript implementation JScript severely confuses the named function expression, making many people come out against a named function expression, and even the version that is currently in use (version 5.8 in IE8) still has the following problems.
Let's take a look at IE in the implementation of the mistakes made, as the saying goes, known to win. Let's take a look at some of the fol

Microsoft JScript objects are a collection of properties and methods.A method is a function that is a member of an object.An attribute is a value or a group of values (in the form of an array or object) and a member of an object.JScript supports four types of objects:Internal objects, generated objects, objects provided by the host (such

Php: function inc ($ val)
The {return $ val 1;} process is also a function, but there is no return value.

The test is done on a desktop system, configured to: 400MHz Celeron processor, 128 MB RAM, operating system Windows Server (5.00.2195), and the Web server is running ASP 3.0 (Asp.dll 5.0.2180.1) IIS 5.0.2157.1. The version of the script engine (JScript and VBScript) is 5.1.0.4615. The system runs a minimal number of services during the test, and the minimum number remains unchanged to ensure the stability of the test environment a
Haha, I can display the row number at last, and it looks pretty good.If the original regular expression is not suitable for matching, you can use the soil method directly.
The improvement of row recognition is simple, that is, segmentation by line break.CodeThen, add the number of rows between rows and combine them.

JScript has two variables: global and local. If a variable is declared outside the definition of any function, the variable is a global variable, and the value of the variable can be accessed and modified throughout the continuous range. If a variable is declared in the Function Definition
Is a local variable. This variable is created and destroyed every time you execute this function, and it cannot be accessed by anything other than this function.
