字符转ascii码：用charCodeAt();
ascii码转字符：用fromCharCode();

看一个小例子

复制代码 代码如下:

<script><BR>str="A";<BR>code = str.charCodeAt(); <BR>str2 = String.fromCharCode(code);<BR>str3 = String.fromCharCode(0x60+26); <P>document.write(code+'<br />');<BR>document.write(str2+'<br />');<BR>document.write(str3);<BR></script>

输出：
