Javascript 如何根据传递给函数的参数更改变量名？

我有一个名为

nameGenerator（）

的函数，它将变量

category

作为参数

在定义此函数之前，我有两对字列表数组：

djentWords1

和

djentWords2

，然后是

hardcoreWords1

和

hardcoreWords2

nameGenerator（）

定义以下变量：

firstNum

和

secondNum

firstWord

和

secondWord

bandName

该函数生成两个随机数（

firstNum

和

secondNum

），介于0和

djentWords1

和

djentWords2

或

hardcoreWords1

和

hardcoreWords2

之间。我的问题是：我能否传递

nameGenerator（）

一个类似“djent”或“hardcore”的参数，并基于该参数，让它使用适当的数组长度来生成随机数？以下是函数的原样：

//First category: djent
var djentWords1 = ["Aman", "Soul", "Cloud", "Calculate", "Pythagoran"];
var djentWords2 = ["NaaKi", "Circlet", "Cykul", "Consciousness", "Daaka"];

//Second category: hardcore
var hardcoreWords1 = ["SMASH", "RAGE", "LIFE", "THESE", "FIRST", "BRASS", "LAST"];
var hardcoreWords2 = ["FIST", "FIGHTER", "BREAKER", "SMASHER", "RUINER", "DAYS", "CHANCE"];


function nameGenerator (category){
    //Randomize
    var firstNum = Math.floor(Math.random() * categoryWords1.length); //categoryWords1 would either be djentWords1 or hardcoreWords1, based on the parameter passed to the function
    var secondNum = Math.floor(Math.random() * categoryWords2.length); //categoryWords2 would either be djentWords2 or hardcoreWords2, based on the parameter passed to the function
    var firstWord = categoryWords1[firstNum]; //firstWord = the word whose position corresponds to the first randomly-generated number
    var secondWord = categoryWords2[secondNum]; //secondWord = the word whose position corresponds to the second randomly-generated number
    var bandName = firstWord + secondWord;
}

提前谢谢-希望这不会太让人困惑。非常感谢所有帮助。

为什么不使用对象（关联数组）

您需要将这些变量声明为数组属性。试试这个：

var djent = {
    words1 : ["Aman", "Soul", "Cloud", "Calculate", "Pythagoran"],
    words2 : ["NaaKi", "Circlet", "Cykul", "Consciousness", "Daaka"]
}
var hardcore = {
    words1 : ["SMASH", "RAGE", "LIFE", "THESE", "FIRST", "BRASS", "LAST"],
    words2 : ["FIST", "FIGHTER", "BREAKER", "SMASHER", "RUINER", "DAYS", "CHANCE"]
}

function nameGenerator (category){
    var firstNum = Math.floor(Math.random() * window[category].words1.length)
       , secondNum = Math.floor(Math.random() * window[category].words2.length)
       , firstWord = window[category].words1[firstNum]
       , secondWord = window[category].words2[secondNum]
       , bandName = firstWord + secondWord;
    return bandName;
}
