Microsoft JScript provides 11 internal (or "built-in") objects. They are array, Boolean, date, function, global, math, number, object, Regexp, error, and string objects. Each object is related Methods and attributes, which are described in the language reference. This section also describes some objects. Array objectThe array subscript can be considered an object attribute, which is referenced by a digital index. Note: The named attributes added t

In IE, there is a little known feature called Conditional compilation. supported since ie4, this feature starting getting some attention when it began showing up in some Ajax related javascripts. an absolute form of object detection, Conditional compilation lets you dictate to IE whether to compile certain parts of your JScript or JavaScript code depending on predefined and user defined conditions. think of it as conditional comments for your script t

1) function example php: functioninc ($ val) {return $ val + 1;} is also a function, but no return value. Jscript, javascript: functioninc (val) {returnval + 1;} process definition is the same as above. VBScript: functioninc 1) function example Php: function inc ($ val) The {return $ val 1;} process is also a function, but there is no return value.

an N-tier system where complex business logic is always encapsulated into components, the script for ASP pages is more primarily to provide "glue" support for integrating business objects and front-end interfaces. In other words, we are not too much dependent on the script itself or the objects provided by the script. On some occasions, however, we cannot afford to use objects. As an example of an array, in both VBScript and

Call functions in Jscript in CPP Calling Jscript functions in C ++ is very simple. Windows provides a msscript. ocx controls can be used to directly operate Jscript: execute a Jscript or call a specified function. I wrote a simple example: L import msscript. ocx. The followi

thousand seconds. (The executed page is called by the Server.Execute of the test Tools page). Similarly, many test scenarios are tested with two test tools pages under different IIS default script engine settings, given that the script engine initialization may affect the execution time of the called page. As before, this factor in all tested scenarios does not affect the timing of execution and the size of the difference in execution results. (However, for Test records, even if the default s

When writing an ASP program, VBScript is usually used. However, you can also use JScript instead of this option. However, when JScript is used as the ASP language, it is slightly inconvenient than VBScript, for example, the GetRows method of RecordSet. RecordSet objects are generally used to operate databases in ASP. If you focus on program efficiency, the GetRow

The concept of set is often used in windows scripts, especially in wmi scripts.The method For traversing a set in vbscript is simple, and the For Each loop can achieve the goal. But in jscriptHow to use collections has plagued me for a long time. I was pessimistic that I could not find any good examples in msdn.Jscript cannot perform set operations.When I almost gave up, I turned out another vbscript wmi e-book and found jscript.The method of using the set, that is, the Enumerator object, which

I think there is a memory leak in Microsoft Internet Explorer 6.0, but on the other hand, it may be a circular reference problem. In my code, I assume that "new object ()" belongs to

When using VBScript, we can use application cache arrays to implement caching, for example: Program code: Copy Code code as follows: Dim Rs,arr Rs. Open conn,sql,1,1 Arr=rs. GetRows () Application.Lock () Application ("Cache") =arr Applicatoin.unlock () In VBScript, arrays can be stored in application objects, but if the ASP's language is selected as JScript, then it's not

In I/O processing, file operations are the most common. JScript can read the file content through FSO or through ADODB. Stream to complete the task. Both objects are standard components of the system. Unless the host space is disabled, it can be used smoothly. An example of using ADODB. Stream/FSO to read files is as follows. The former only supports files that are saved in a UTF-8 character set, while the

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.
