var GB2312UnicodeConverter = { ToUnicode: function (str) { return escape(str).toLocaleLowerCase().replace(/%u/gi, '\\u'); } , ToGB2312: function (str) { return unescape(str.replace(/\\u/gi, '%u')); } }; var str = '上海', unicode; document.write(str + '<br/>'); unicode = GB2312UnicodeConverter.ToUnicode(str); document.write('汉字转换为Unicode代码:' + unicode + '<br/><br/>'); document.write('Unicode代码转换为汉字:' + GB2312UnicodeConverter.ToGB2312(unicode));转载自:http://www.cnblogs.com/chu888chu888/archive/2012/02/15/2352169.html
