You cannot split the int, you need to have a string data type for this code to work!
您不能拆分 int，您需要有一个字符串数据类型才能使此代码工作！
So, I would like to suggest to first split it and then convert it to int as
所以，我想建议先拆分它，然后将其转换为 int 作为
var numbers = "1, 2, 3";
var eachNumber = numbers.split(",");
/* now parse them or whatso ever */
This will work, as you're just splitting the string. And then you will parse it just the way you did it in the first method (of yours).
这将起作用，因为您只是在拆分字符串。然后你将按照你在第一种方法（你的）中所做的方式解析它。

var intArray = prompt("...").split(" ").map(Number);

You would need to change the number to string, then split it.
您需要将数字更改为字符串，然后将其拆分。
You would then want to return it to an integer.
然后，您可能希望将其返回为整数。
var myNumber = parseInt(prompt("Enter your number"));
var tempString = myNumber + "";
var arr = tempString.split("");
console.log(arr);

myNumberis an integer variable, which does not hold .split()method, it belongs to string variable.
myNumber是一个整型变量，不持有.split()方法，属于字符串变量。
var no = "12 13 14 15";
var noV = no.split(" ")
