static
importClass(classPath

importScript
static
importScript(scriptPath
:
String)
:
void
Imports all functions from the specified script. Variables are not imported
from the script and must be accessed through helper functions.
The script path has the following syntax: [cartridgename:]scriptname, where
cartridgename identifies a cartridge where the script file is located. If
cartridgename is omitted the script file is loaded from the same cartridge
in which the importing component is located.
Examples:
importScript( 'example.ds' ) imports the script file example.ds from the same cartridge
importScript( 'abc:example.ds' ) imports the script file example.ds from the cartridge 'abc'
Parameters:
scriptPath
-
the path to the script.
isFinite
static
isFinite(number
:
Number)
:
boolean
Returns true if the specified Number is finite.
Parameters:
number
-
the Number to test.
Returns:
true if the specified Number is finite, false otherwise.
isNaN
static
isNaN(object
:
Object)
:
boolean
Test the specified value to determine if it
is not a Number.
Parameters:
object
-
the Object to be tested as a number
Returns:
True if the object is not a number
isXMLName
static
isXMLName(name
:
String)
:
boolean
Determines whether the specified string is a valid name for an
XML element or attribute.
Parameters:
name
-
the String specified
Returns:
True if the string is a valid name
parseFloat
Parses a String into an float Number.
Parameters:
s
-
the String to parse.
Returns:
Returns the float as a Number.
parseInt
Parses a String into an integer Number using the
specified radix.
Parameters:
s
-
the String to parse.
radix
-
the radix to use.
Returns:
Returns the integer as a Number.
parseInt
Parses a String into an integer Number.
This function is a short form for the call to
parseInt(String, Number) with automatic determination of the radix.
If the string starts with "0x" or "0X" then the radix is 16. If the string starts with "0" the the radix is 8. In all other cases the radix is 10.
API Versioned:
No longer available as of version 16.1.
Parameters:
s
-
the String to parse.
Returns:
Returns the integer as a Number.
parseInt
Parses a String into an integer Number.
This function is a short form for the call to
parseInt(String, Number) with automatic determination of the radix.
If the string starts with "0x" or "0X" then the radix is 16. In all other cases the radix is 10.
API Versioned:
From version 16.1.
ECMAScript 5 compliance: removed support for octal numbers.
Parameters:
s
-
the String to parse.
Returns:
Returns the integer as a Number.
require
The require() function supports loading of modules in JavaScript. The function works similar to the require() function
in CommonJS. The general module loading works the same way, but the exact path lookup is slightly different
and better fits into Demandware concepts. Here are the details for the lookup:
- If the module name starts with "./" or "../" then load it relative to the current module. The module can be a file or a directory. A file
extension is acknowledged, but not required. If it's a directory a 'package.json' or a 'main' file is expected.
If the 'package.json' does not contain a main entry, then default to main file in the directory.
Access to parent files can't go beyond the cartridges directory. Access to other cartridges is explicitly allowed.
- If the module name starts with "~/" it's a path relative to the current cartridge.
- If the module name starts with "*/" try to find the module in all cartridges that are assigned to the current site.
- A module with the name "dw" or which starts with "dw/" references Demandware built-in functions and classes.
For example
var u = require( 'dw/util' );
loads the classes in the util package, which can be then used like
var h = new u.HashMap();
- A module, which doesn't start with "./" or "../" is resolved as top level module.
- The module name is used to find a folder in the top cartridge directory, typically a cartridge itself, but it can also be a simple folder.
- If nothing is found, the module name is used to look into a special folder called "modules" in the top cartridge directory. That folder
can be used by a developer to manage different modules. For example a developer could drop a module like "less.js" just into that folder.
If the require function is used to reference a file then an optional file extension is used to determine the content of the file. Currently
supported are the extensions ordered by priority:
- js - JavaScript file
- ds - Demandware Script file
- json - JSON file
Parameters:
path
-
the path to the JavaScript module.
Returns:
an object with the exported functions and properties.
trace
Formats and prints the message using the specified params and returns
the formatted message. The format message is a Java MessageFormat
expression. Printing happens in the script log output.
Parameters:
msg
-
the message to format.
params
-
one, or multiple parameters that are used to format the message.
unescape
Decode an escaped String.
Parameters:
string
-
the String to decode.
Returns:
a copy of the String where hexadecimal character sequences are replace by Unicode characters.
