NOTE: If [s] is marked as a static method, it can be used without instantiating an object.

 

String. endswith (suffix)

Determines whether the string ends with the specified suffix.

 
VaRIstxt = mystring. endswith ("Some_file.txt",". Txt");
 

 
// Istxt = true
 

 

[S] String. Format (format, argS)

Replace the formatting items in the string with the corresponding parameter values. ARGs can be a single object or an array containing multiple items.

 
VaRUser = {
 

 
Firstname:'John',
 

Lastname:'Doe',
 

 
DOB:NewDate (1975, 1, 17 )};
 

 
VaRLabel = string. Format ("User name: {0} {1}, born {2: d }",
 

 
User. firstname, user. lastname, user. DOB ));
 

 
// Label = "User name: John Doe, born 02/17/1975"
 

 

[S]String. localeformat (format, argS)

The function is similar to string. Format (format, argS), but the format is related to the region settings.

 

String. startswith (prefix)

Determines whether the string starts with the specified prefix. See string. endswith (suffix ).

 

String. Trim ()

Returns a copy of the original string, but removes all blank characters (such as spaces or tabs) starting and ending with the original string.

VaRMystring ="A string";
 

 
Mystring = mystring. Trim ();
 

 
// Mystring = "a string"
 

 

String. trimend ()

Returns a copy of the original string, but removes all spaces (such as spaces or tabs) at the end of the original string.

 
VaRMystring ="A string";
 

 
Mystring = mystring. Trim ();
 

 
// Mystring = "a string"
 

 

String. trimstart ()

Returns a copy of the original string, but removes all blank characters (such as spaces or tabs) Starting with the original string.

 
VaRMystring ="A string";
 

 
Mystring = mystring. Trim ();
 

// Mystring = "a string"
 

 

[S]Object. GetType (Instance)

To return the type of the specified object, see object. gettypename (instance ).

 

[S]Object. gettypename (Instance)

Returns a fully qualified type string for the object at runtime.

 
Type. registernamespace ("Samples");
 

 
// Define and register a samples. Rectangle class.
 

 
Samples. Rectangle =Function(Width, height ){
 

 
This. _ Width = width;
 

 
This. _ Height = height;
 

 
}
 

Samples. Rectangle. registerclass ("Samples. rectangle");
 

 
VaRA =NewSamples. rectangle (200,100 );
 

 
VaRName = object. gettypename ();
 

 
VaRType = object. GetType ();
 

 
SYS. Debug. Trace ("The type name of object \" A \ "is :"+ Name );
 

 
SYS. Debug. tracedump (type );
 

 
/* The result is:
 

 
The type name of object "a" is: samples. rectangle
 

 
Tracedump {function}
 

 
Prototype {samples. Rectangle}
 

_ Typename: samples. rectangle
 

 
_ Class: True
