怎么取得汉字拼音？（Web Javascript）

[Eden]

在网页的一个文本框中输入汉字时，怎样才能取得它的读音以自动显示在另一个文本框中？是否需要IME相关知识？最好提供一个例子，谢谢各位大虾。

[alexxing]

不需要IME相关知识，汉字编码是按汉语拼音顺序排列的
只要有两者的对照表就可以

var MaxCode = -10247;

表中每一行是拼音，和该拼音对应的所有汉字的编码的起始值
MaxCode 是所以汉字编码的最大值
对照表有了，程序你自己该会写了吧

[alexxing]

获取字符串中字符的编码用 str.charCodeAt(i)

[Eden]

谢谢大虾。
还有个问题，你的对照表怎么弄出来的？

[Eden]

还有，多音字的问题如何解决？

[alexxing]

这个不难，许多地方都有资料
而且，汉字编码是顺序排列的，我是用 Delphi 做了一个程序，让整数顺序递增，并把整数当作汉字编码输出，再做一些分析，就可以了
windows 的目录下就有名为 gbk.txt 的文件，只不过平常没人注意罢了

[alexxing]

多音字的问题？

纯粹在难为人嘛，呵呵

汉字的多音字，在编码上并没有什么规律，要处理多音字，就得把所有的多音字的数据存进数据库，用 javascript 估计是不可能了（文件太大，根本不可能用在网页里）

[qiushuiwuhen]

原理很简单，但重要的是谁去做？反正我是花了好几个小时才拼好音的

http://www.csdn.net/Develop/read_article.asp?id=13846

ps.多音字和词组有关系，还需要手工录入。
而且这段对照表其实只能拼一般（一半）的汉字

[Tomcat4]

var s ="昨天的作业";
for(var i=0;i<s.length;i++)
alert(s.charCodeAt(i));

怎么昨天的“昨”输出的是26152，而不是上面表上的-10254.是不是有个什么转换？

[alexxing]

没错啊，“昨”的GB码是 0xd7f2 = 55282 = -10254

[richardluopeng]

我有一个例子，信箱我发给你！

[Eden]

非常感谢各位大虾热心相助。
to:richardluopeng(罗罗) 例子就不用了。

[alexxing]

不好意思，charCodeAt() 返回的不是 GB 码，俺太粗心了
你可以参照秋水无恨的例子，用VBSCRIPT获得GB码
