JavaScript：使用函数分割字符串并返回

Question

I don't know what I'm doing wrong here. Tried several thinks but the function doesn't work/return properly (The html code is okay)

var divResult = document.getElementById("divResult");
var naam;

function splitsen(naam){
    var res = naam.split(" ");
    document.write(res[0]);
    var voornaam = res[0];
    var achternaam = res[1];
    var tnaam = [voornaam, achternaam];
return tnaam;
}

naam = parseInt(prompt("Geef je voornaam en achternaam in gescheiden met een spatie"));

var voornaam = splitsen(naam)[0];
var achternaam = splitsen(naam)[1];
divResult.innerHTML = "oefening 8";
divResult.innerHTML += "Voornaam: " + voornaam;
divResult.innerHTML += "Achternaam" + achternaam;
divResult.innerHTML += "Email: " + voornaam + "." + achternaam + "@student.arteveldehs.be";

Answer 1

parseInt('My Name'); returns NaN .

Remove the parseInt() , and just keep it as:

var naam = prompt('Input your name seperated by a space.');

Answer 2

I could spot 2 problems in your code:

1- The parameter name to your function is the same name as that of a global variable . It is probable that any references to 'naam' in your function use the global variable instead of what you pass. Regardless, don't do that.

2- parseInt will take a string and extract an integer out of it and returns a number . number types doesn't have the split() method and you probably wanted a string containing the name.
