将字符串转换为变量名称。 （JavaScript的）

Question

I did look at the previous questions, but they are for integer values and I need an answer for text values.

I asked a question relevant to this earlier in the week, but here goes. As seen below, I have Make[x] equal to some string value (Acura, Honda, Toyota). When I pass that Make[x] into the function Models(Make), how can I get that string to become a variable name, for the variables Acura, Honda and Toyota within the Models(Make) function?

function Models(Make){
var Acura=['RSX','NSX','Integra',];
var Honda=['Accord','Civic','Prelude',];
var Toyota=['MR2','Celica','Camry',];
var holder = Make;
var Model = holder[Math.floor(Math.random()*holder.length)];
return Model;
}

function main(){
var Makes=['Acura','Honda','Toyota',];
var Make = Makes[Math.floor(Math.random() * Makes.length)];
var Model = Models(Make);
var Out = Make + " " + Model;
return Out;
}

document.write(main());

If run, you will get the name of the Make, but instead of a model it spits out a letter from the name of the Model in place of the make.

Answer 1

You can't do what you're asking with what you have currently, but it would make more sense to create an object of the models anyway

function Models(Make) {
    var Models = {"Acura": ['RSX','NSX','Integra'] /* snip */};
    return Models[Make][random()];
}
