Ecmascript 6包括“解构赋值”(正如kangax提到的)，因此在所有浏览器(不仅仅是Firefox)中，您将能够捕获值的数组，而不必为捕获它们的唯一目的而创建命名数组或对象。

//so to capture from this function
function myfunction()
{
 var n=0;var s=1;var w=2;var e=3;
 return [n,s,w,e];
}

//instead of having to make a named array or object like this
var IexistJusttoCapture = new Array();
IexistJusttoCapture = myfunction();
north=IexistJusttoCapture[0];
south=IexistJusttoCapture[1];
west=IexistJusttoCapture[2];
east=IexistJusttoCapture[3];

//you'll be able to just do this
[north, south, west, east] = myfunction(); 

你已经可以在Firefox中尝试了!

从ES6开始，你可以这样做

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

let {dCodes, dCodes2} = newCodes()

返回表达式{dCodes, dCodes2}是属性值的简写，等价于这个{dCodes: dCodes, dCodes2: dCodes2}。

最后一行的赋值叫做对象析构赋值。它提取对象的属性值并将其赋值给同名变量。如果你想把返回值赋给不同名称的变量，你可以这样做let {dCodes: x, dCodes2: y} = newCodes()

几天前，我有类似的要求，从我创建的函数中获得多个返回值。

从许多返回值，我需要它只返回特定的值为一个给定的条件，然后其他返回值对应于其他条件。

以下是我如何做到这一点的例子:

功能:

function myTodayDate(){
    var today = new Date();
    var day = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
    var month = ["January","February","March","April","May","June","July","August","September","October","November","December"];
    var myTodayObj = 
    {
        myDate : today.getDate(),
        myDay : day[today.getDay()],
        myMonth : month[today.getMonth()],
        year : today.getFullYear()
    }
    return myTodayObj;
}

从函数返回的对象获取所需的返回值:

var todayDate = myTodayDate().myDate;
var todayDay = myTodayDate().myDay;
var todayMonth = myTodayDate().myMonth;
var todayYear = myTodayDate().year;

回答这个问题的关键是分享以良好格式获取Date的方法。希望对你有所帮助:)

只返回一个对象文字

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


var result = newCodes();
alert(result.dCodes);
alert(result.dCodes2);

使用模板字面量' ${}'可以返回一个包含许多值和变量的字符串

如:

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

它既简短又简单。
