JS 字符/ASCII码转换

字符转ascii码：用charCodeAt();

ascii码砖字符：用fromCharCode();

 

看一个小例子

<script>

str="A";

code = str.charCodeAt();

str2 = String.fromCharCode(code);

str3 = String.fromCharCode(0x60+26);

document.write(code+'<br />');

document.write(str2+'<br />');

document.write(str3);

</script>

输出：

65

A

z
