The scope of variables defined by var in JScript does not remember when the JScript syntax tutorial was read. 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

Conditional compilation can use new features of JScript and is compatible with older versions that do not support this feature.
Use the @ cc_on statement, @ if, or @ set statement to activate Conditional compilation. Some typical uses of Conditional compilation include the use of new features in JScript, embedded debugging support in the script, and trackingCode.
Conditional compilation code is usually pu

This article mainly introduces the methods of JScript reading and writing binary files, involving the use of ActiveXObject objects in JavaScript, which has some reference value, and the friends who need them can refer to

Some Reserved Words In JScript cannot be used in identifiers. Reserved Words have special meanings to the JScript Language. They are part of the language syntax. Using reserved words will cause compilation errors when loading scripts.
JScript also contains reserved words for future use. These words are not part of the current
PHP, JScript, and VBScript functions and class syntax. 1) function example php: functioninc ($ val) {return $ val + 1;} is also a function, but no return value. Example of the jscript, javascript: functioninc (val) {returnval + 1;} process 1) function
Php: function inc ($ val)
{Return $ val + 1 ;}
The process is also a function, but there is no return value.Jscript, javascript:Function inc (val){Return val
I have never noticed the difference between the implicit variable Declaration In JScript and the VaR explicit variable declaration. Although some problems have been encountered in the declaration, it has not caused much attention. I wrote several functions today and checked the reference manual. I felt it was necessary to change the traditional implicit declaration practices to avoid unnecessary troubles. The Manual describes the "variable Declaration

Js|jscript returns the year value in the Date object.
Dateobj.getyear ()
The required option Dateobj parameter is a Date object.
Description
This method is outdated and is provided to maintain backward compatibility. Use the getFullYear method instead.
For the 1900-1999 period, the returned year value is a two-digit integer that represents the gap between the saved year and the 1900 year. and the
In other years, the return value is a four-bit

Strvariable.fontcolor (Colorval)
Parameters
Strvariable
Required option. Any String object or literal.
Colorval
Required option. Is the string value that contains the color value. Can be a hexadecimal value for a color, or a predefined color name.
Description
The following example illustrates the FontColor method:
var strvariable = "This is a string";
strvariable = Strvariable.fontcolor ("Red");

I don't remember when I looked at the grammar tutorial for JScript, which says it's perfectly legal to ignore the VAR keyword when declaring a variable. It was also because of the thought that JavaScript was loosely-typed language, so Var might really be a device. But it often turns out that the consequences of being taken for granted are unreliable.

As a powerful tool for text replacement, search, and extraction in pattern matching, the application of the regular expression (Regular Expression) has gradually penetrated into network development from the UNIX platform, JScript, a scripting language for servers and clients, is increasingly integrating regular expression applications to make up for its lack of processing capabilities in the text. Here, we take jscript5.5 as an example to give an over

Recently, we have made object-oriented extensions for JScript so that you can define classes in JScript (TM) and write real object-oriented code.
