要是我理解了你的问题，你是希望这样吧：

var a = [ 0 , 89 ,2 , 3];

var b = [ "san" , "si" , "wu" , "liu"];

var merge = a.map(function(ai, i){
    return {a:ai, b:b[i]};
})
merge.sort(function(am1, am2){
    return am1.a - am2.a
})
// 允许生成新的数组引用就用map, 要是不允许生成新的数组引用，就挨个赋值
b = merge.map(function(ab, i){
    return ab.b
}) 
console.log(b);
