const converter = OpenCC.Converter({ from: 'hk', to: 'cn' });
// Set the conversion starting point to the root node, i.e. convert the whole page
const rootNode = document.documentElement;
// Convert all elements with attributes lang='zh-HK'. Change attribute value to lang='zh-CN'
const HTMLConvertHandler = OpenCC.HTMLConverter(converter, rootNode, 'zh-HK', 'zh-CN');
HTMLConvertHandler.convert(); // Convert  -> 汉语
HTMLConvertHandler.restore(); // Restore  -> 漢語

API

• .Converter({}): declare the converter's direction via locals.
  • default: { from: 'tw', to: 'cn' }
  • syntax : { from: local1, to: local2 }
• locals: letter codes defining a writing local tradition, occasionally its idiomatic habits.
  • cn: Simplified Chinese (Mainland China)
  • tw: Traditional Chinese (Taiwan)
    • twp: with phrase conversion (ex: 自行車 -> 腳踏車）
  • hk: Traditional Chinese (Hong Kong)
  • jp: Japanese Shinjitai
  • t: Traditional Chinese (OpenCC standard. Do not use unless you know what you are doing)
• .CustomConverter([]) : defines custom dictionary.
  • default: []
  • syntax : [ ['item1','replacement1'], ['item2','replacement2'], … ]
• .HTMLConverter(converter, rootNode, langAttrInitial, langAttrNew ) : uses previously defined converter() to converts all HTML elements text content from a starting root node and down, into the target local. Also converts all attributes lang from existing langAttrInitial to langAttrNew values.
• lang attributes : html attribute defines the languages of the text content to the browser, at start (langAttrInitial) and after conversion (langAttrNew).
  • syntax convention: IETF languages codes, mainly zh-TW, zh-HK, zh-CN, zh-SG,…
• ignore-opencc : html class signaling an element and its sub-nodes will not be converted.
