把 0 转成 A，把 1 转成 B，直到 Z
目前我写的
js 代码
function i_to_char(z) {
var i = z;
if(z >= 0 && z < 26) {
i = i + 65;
}else{
return "undefined z in i_to_char(z)"
}
return String.fromCharCode(i);
}
大家有更精简的写法？
function i_to_char(z) {
return (z >= 0 && z < 26) ? String.fromCharCode(z + 65) : "undefined z in i_to_char(z)"
}
Number.prototype.to_char = function() {
return (this >= 0 && this < 26) ? String.fromCharCode(this + 65) : "number >= 0 and < 25"
};
Number.prototype.to_char = function() {
return String.fromCharCode(this + 65)
};
0..to_char()
1..to_char()
2..to_char()
