nsIStringBundle 编辑

intl/strres/public/nsIStringBundle.idlScriptable This interface provides functions for retrieving both formatted and unformatted strings from a properties file Inherits from: nsISupports Last changed in Gecko 1.7

This interface is used by XUL:stringbundle to retrieve strings. It is recommended that you use the methods of XUL:stringbundle to access these functions unless necessary. Alternatively, a string bundle can be created within a javascript context with nsIStringBundleService.

Method overview

wstring formatStringFromID(in long aID, [array, size_is(length)] in wstring params, in unsigned long length);

wstring formatStringFromName(in wstring aName, [array, size_is(length)] in wstring params, in unsigned long length);

nsISimpleEnumerator getSimpleEnumeration();

wstring GetStringFromID(in long aID);

wstring GetStringFromName(in wstring aName);

Methods

formatStringFromID()

Returns a formatted string with the given ID from the string bundle, where each occurrence of %S (uppercase) is replaced by each successive element in the supplied array. You may also use other formatting codes. You can only pass Unicode strings in. The ID should refer to a string in the bundle that uses %S, and the number of strings you pass MUST be the same here and in the properties file (That is you can't omit %1 and use only %2). Do NOT try to use any other types. This uses nsTextFormatter::smprintf.

wstring formatStringFromID(

  [array, size_is(length)] in wstring params,
  in unsigned long length
);

formatStringFromName()

Returns a formatted string with the given key name from the string bundle, where each occurrence of %S (uppercase) is replaced by each successive element in the supplied array. You may also use other formatting codes, but can only pass Unicode strings in. The name should refer to a string in the bundle that uses %S, and the number of strings you pass MUST be the same here and in the properties file (That is you can't omit %1 and use only %2). Do NOT try to use any other types. This uses nsTextFormatter::smprintf to do the dirty work.
