用人在知道里面提问，如何用javascript程序把汉字转换为拼音的首字母，帖子地址是：/question/41377061.html
我分析一下以后，写了下面的把汉字转换为拼音的程序，但是帖子只要拼音的首字母，所以那里只贴了一个更简单化的版本。
程序原理很简单，网上可以找到汉字拼音的数据字典，但是由于大家都知道GB2312编码里面汉字是按拼音排序的，只要知道各个拼音为首的汉字代码，就可以计算所有汉字的拼音代码了。
程序有一个关键，就是Javascript对汉字是自动使用unicode编码，为了获取起GB2312的ASCII编码值，我使用了VBSCRIPT来写了两个函数，在JAVASCRIPT程序里面调用VBSCRIPT的函数实现代码转换。
完整程序如下（把以下代码保存为一个html文件用IE打开，在汉字栏里面输入内容，光标离开的时候拼音栏就会显示相应的拼音）：
<mce:script language="vbscript"><!--function vbChr(c) vbChr = chr(c) end functionfunction vbAsc(n) vbAsc = asc(n) end function // --></mce:script><mce:script language=javascript><!--var py1=new
