通过对象列表将ID数组映射到字符串数组。

var myIds = [3, 4, 2];

var myObj = [
    {id:1, name:'one'}, 
    {id:2, name:'two'},
    {id:3, name:'tree'},
    {id:4, name:'four'}];

// need to obtain ['tree', 'four', 'two']

var idsToNames= function(ids, objects) {
    var myNames = myIds.map(function(id){
        // transform id to name
        foreach(o in objects){
            if (i.id == id) 
                return o.name;
        }
    });
    return myNames;
}
var myIds = [3, 4, 2];

var myObj = [
    {id:1
