把字符串按照特定的字母顺序进行排序的js代码

例如，给一个特定的字母顺序，"a","o","e","u","y","i"，请把'aiye','oeu','ayo','eoyiu','yuo','you','iao'这7个字符串按照给定的字母顺序排序。

我的思路是把那几个给定的6个字母分别等效成0-5的数字，然后把那7个字符串中的字母替换成0-5中的数字，再用sort方法进行排序，代码如下：
代码如下:

var word = ['aiye','oeu','ayo','eoyiu','yuo','you','iao']; 
var obj = {a:0,o:1,e:2,u:3,y:4,i:5}; 
var obj1 = {0:'a',1:'o',2:'e',3:'u',4:'y',5:'i'}; 
for(var index in word){ 
var word1 = word[index]; 
var word3 = ""; 
for(var i = 0; i< word1.length; i ++ ){ 
word3 += obj[word1[i]]; 
}; 
word[index] = word3 
} 
word.sort(); 
for(var index in word){ 
var word1 = word[index]; 
var word3 = ""; 
for(var i = 0; i< word1.length; i ++ ){ 
word3 += obj1[word1[i]]; 
}; 
word[index] = word3 
} 
console.log(word); 
 
 代码如下:
