在JavaScript中返回多个值？ [英] Return multiple values in JavaScript?

问题描述

我试图在JavaScript中返回两个值。那可能吗？

I am trying to return two values in JavaScript. Is that possible?

var newCodes = function() {  
    var dCodes = fg.codecsCodes.rs;
    var dCodes2 = fg.codecsCodes2.rs;
    return dCodes, dCodes2;
};

推荐答案

不，但你可以返回一个包含你的值的数组：

No, but you could return an array containing your values:

var newCodes = function() {
    var dCodes = fg.codecsCodes.rs;
    var dCodes2 = fg.codecsCodes2.rs;
    return [dCodes, dCodes2];
};

然后您可以这样访问它们：

Then you can access them like so:

var codes = newCodes();
var dCodes = codes[0];
var dCodes2 = codes[1];

如果你想在每个返回值上放置标签（更容易维护），你可以返回一个对象：

If you want to put "labels" on each of the returned values (easier to maintain), you can return an object:

var newCodes = function() {
    var dCodes = fg.codecsCodes.rs;
    var dCodes2 = fg.codecsCodes2.rs;
    return {
        dCodes: dCodes,
        dCodes2: dCodes2
    };
};

要访问它们：

var codes = newCodes();
var dCodes = codes.dCodes;
var dCodes2 = codes.dCodes2;
