StaticextensionSpecifies the extension used for language files.
StaticloadSpecifies if the default file for a given basename should be loaded. Default is true.
StaticloadSpecifies if the specific language file file for a given basename should be loaded. Default is true.
StaticresourcesStaticresourcesSpecifies whether values in resource files are encoded with \u or percentage. Default is false.
StaticaddAdds the default and current language properties file for the specified basename. Existing keys are overridden as new files are added. If no callback is used then the request is synchronous.
Example:
At application startup, additional resources may be added using the following code:
Translations.add('resources/editor');
The basename for which the file should be loaded.
The language for which the file should be loaded.
Optional callback for asynchronous loading.
StaticgetReturns the value for the specified resource key.
Example: To read the value for 'welcomeMessage', use the following:
let result = Translations.get('welcomeMessage') || '';
This would require an entry of the following form in one of the English language resource files:
welcomeMessage=Welcome to mxGraph!
The part behind the || is the string value to be used if the given resource is not available.
String that represents the key of the resource to be returned.
Array of the values for the placeholders of the form {1}...{n} to be replaced with in the resulting string.
Optional string that specifies the default return value.
StaticgetStaticgetHook for subclassers to return the URL for the special bundle. This
implementation returns basename + '_' + lan + <extension> or null if
Translations.loadSpecialBundle is false or lan equals Client.defaultLanguage.
If Translations#languages is not null and Client.language contains
a dash, then this method checks if Translations.isLanguageSupported returns true
for the full language (including the dash). If that returns false the
first part of the language (up to the dash) will be tried as an extension.
If Translations#language is null then the first part of the language is used to maintain backwards compatibility.
The basename for which the file should be loaded.
The language for which the file should be loaded.
StaticisStaticloadStaticparseStaticreplaceReplaces the given placeholders with the given parameters.
String that contains the placeholders.
Array of the values for the placeholders of the form {1}...{n} to be replaced with in the resulting string.
Implements internationalization. You can provide any number of resource files on the server using the following format for the filename: name[-en].properties. The en stands for any lowercase 2-character language shortcut (eg. de for german, fr for french).
If the optional language extension is omitted, then the file is used as a default resource which is loaded in all cases. If a properties file for a specific language exists, then it is used to override the settings in the default resource. All entries in the file are of the form key=value. The values may then be accessed in code via get. Lines without equal signs in the properties files are ignored.
Resource files may either be added programmatically using add or via a resource tag in the UI section of the editor configuration file, eg:
The above element will load examples/resources/mxWorkflow.properties as well as the language specific file for the current language, if it exists.
Values may contain placeholders of the form {1}...{n} where each placeholder is replaced with the value of the corresponding array element in the params argument passed to get. The placeholder {1} maps to the first element in the array (at index 0).
See Client.language for more information on specifying the default language or disabling all loading of resources.
Lines that start with a # sign will be ignored.
Special characters
To use unicode characters, use the standard notation (eg. \u8fd1) or %u as a prefix (eg. %u20AC will display a Euro sign). For normal hex encoded strings, use % as a prefix, eg. %F6 will display a "o umlaut" (ö).
See resourcesEncoded to disable this. If you disable this, make sure that your files are UTF-8 encoded.
Asynchronous loading
TODO the following is taken from mxGraph and is probably no longer accurate
By default, the core adds two resource files synchronously at load time. To load these files asynchronously, set LoadResources to false before loading Client and use loadResources instead.
