this.runThisFunctionOnCall = function(){
array1;
array2;
array3;
return ????
}
回答by Caspar Kleijne
as an array;)
作为一个数组;)
this.runThisFunctionOnCall = function(){
var array1 = [11,12,13,14,15];
var array2 = [21,22,23,24,25];
var array3 = [31,32,33,34,35];
return [
array1,
array2,
array3
];
}
call it like:
称之为：
var test = this.runThisFunctionOnCall();
var a = test[0][0] // is 11
var b = test[1][0] // is 21
var c = test[2][1] // is 32
or an object:
或一个对象：
this.runThisFunctionOnCall = function(){
var array1 = [11,12,13,14,15];
var array2 = [21,22,23,24,25];
var array3 = [31,32,33,34,35];
return {
array1: array1,
array2: array2,
array3: array3
};
}
call it like:
称之为：
var test = this.runThisFunctionOnCall();
var a = test.array1[0] // is 11
var b = test.array2[0] // is 21
var c = test.array3[1] // is 32

Simply put your arrays into an array and return it I guess.
只需将您的数组放入一个数组中并返回它我猜。

I would suggest making an array of arrays. In other words, a multidimensional array. That way, you can reference all arrays outside of the function within that one returned array. To learn more on how to do this, this link is quite useful: http://sharkysoft.com/tutorials/jsa/content/019.html
我建议制作一个数组数组。换句话说，一个多维数组。这样，您可以在返回的数组中引用函数之外的所有数组。要了解有关如何执行此操作的更多信息，此链接非常有用：http: //sharkysoft.com/tutorials/jsa/content/019.html
