在python中能让首字母大写的函数：如何用javajavascriptpython获取中文的拼音首字母(1)

最近需要实现拼音首字母搜索，顺便整理一下其他语言的拼音首字母搜索的代码进行备用，有需要的直接拿走。话不多说，直接上码

JavaScript，只保留了核心的提取拼音的部分，如果需要可以留下邮箱或者私信我

第一种:

直接上代码(有个别中文无法识别):

import java.io.UnsupportedEncodingException; /** * * @author yuki_ho * */ public class ChineseCharToEnUtil { private final static int[] li_SecPosValue = { 1601 1637 1833 2078 2274 2302 2433 2594 2787 3106 3212 3472 3635 3722 3730 3858 4027 4086 4390 4558 4684 4925 5249 5590 }; private final static String[] lc_FirstLetter = { "a" "b" "c" "d" "e" "f" "g" "h" "j" "k" "l" "m" "n" "o" "p" "q" "r" "s" "t" "w" "x" "y" "z" }; /** * 取得给定汉字串的首字母串即声母串 * @param str 给定汉字串 * @return 声母串 */ public String getAllFirstLetter(String str) { if (str == null || str.trim().length() == 0) { return ""; } String _str = ""; for (int i = 0; i < str.length(); i ) { _str = _str this.getFirstLetter(str.substring(i i 1)); } return _str; } /** * 取得给定汉字的首字母即声母 * @param chinese 给定的汉字 * @return 给定汉字的声母 */ public String getFirstLetter(String chinese) { if (chinese == null || chinese.trim().length() == 0) { return ""; } chinese = this.conversionStr(chinese "GB2312" "ISO8859-1"); if (chinese.length() > 1) // 判断是不是汉字 { int li_SectorCode = (int) chinese.charAt(0); // 汉字区码 int li_PositionCode = (int) chinese.charAt(1); // 汉字位码 li_SectorCode = li_SectorCode - 160; li_PositionCode = li_PositionCode - 160; int li_SecPosCode = li_SectorCode * 100 li_PositionCode; // 汉字区位码 if (li_SecPosCode > 1600 && li_SecPosCode < 5590) { for (int i = 0; i < 23; i ) { if (li_SecPosCode >= li_SecPosValue[i] && li_SecPosCode < li_SecPosValue[i 1]) { chinese = lc_FirstLetter[i]; break; } } } else // 非汉字字符如图形符号或ASCII码 { chinese = this.conversionStr(chinese "ISO8859-1" "GB2312"); chinese = chinese.substring(0 1); } } return chinese; } /** * 字符串编码转换 * @param str 要转换编码的字符串 * @param charsetName 原来的编码 * @param toCharsetName 转换后的编码 * @return 经过编码转换后的字符串 */ private String conversionStr(String str String charsetName String toCharsetName) { try { str = new String(str.getBytes(charsetName) toCharsetName); } catch (UnsupportedEncodingException ex) { System.out.println("字符串编码转换异常：" ex.getMessage()); } return str; } public static void main(String[] args) { ChineseCharToEnUtil cte = new ChineseCharToEnUtil(); System.out.println("获取拼音首字母：" cte.getAllFirstLetter("广州")); } }
