返回多个值并访问它们? [英] Return multiple values and access them?

问题描述

我将如何构造它以返回多个值(消息和名称)，并能够在js.html文件中访问它们?

How would I structure this to return multiple values (message and name), and be able to access them in the js.html file?

 

- code.gs

function createArtistTable(name)
{
    var message = "test";

    //return message and name
}

- js.html

function openArtistTable(name)
{
    google.script.run
        .withSuccessHandler(openSuccess)
        .withFailureHandler(openFailure)
        .createArtistTable(name)
}

function openSuccess(//have 2 values here -- var1, var2)
{
    console.log(var1);
    console.log(var2);
}

推荐答案

一个函数只能返回一个值.

A function can only return one value.

因此，执行此操作的方法是将它们包装在数组或对象中.

So the way to do this is to wrap them together inside an array or object.

function return2Vals()
{
    var var1;
    var var2;
    //Code that does stuff with var1 and var2
    ///
    ///
    //Create an array with the values and return it.
    var results = [var1, var2];
    return results;
}

使用结果:

var vals = return2Vals();
console.log("One of the return values is:", vals[0]);
console.log("The other return value is:", vals[1]);

或者，您可以使用一个对象，基本上可以做任何您想做的事 通过使用对象:

Alternatively you could use an object and basically do whatever you want by using an object:

function returnSomeValsAsObj()
{
    var var1;
    var var2;
    //Code that does stuff with var1 and var2
    ///
    ///
    //Create an object with the values and return it.
    var results = {primary_result: var1, secondary_result: var2, accompanying_message: "some message"};
    return results;
}

使用:

var results = returnSomeValsAsObj();
console.log(results.primary_result);
console.log(results.secondary_result);
console.log(results.accompanying_message);
