JS既然是代码，自然转不了汉字，而且也毫无意义。如果是把汉字代码转为汉字，可以使用String.fromCharCode(字符的Ascii码)，就可实现将ascii码转换成字符。
function _convert(str){
var arr = ["一","二","三","四","五","六","七","八","九","十"]
for (var i = 0 i < arr.length i++) {
str = str.replace(new RegExp(arr[i], "g"), (i+1))
}
return str
}
// 使用
var str = "一二三三九一"
var result = _convert(str)
result // 123391
