JS文件不起作用

Question

下面是我的JS文件中的代码：

function arrayContains(array, value){ 
    return array.indexOf(value) > -1; 
} 
var possibleOptions = ["male", "female", "m", "f"]; 
var gender = prompt("What's your gender?",""); 
while(!arrayContains(possibleOptions, gender)) 
    gender = prompt("Invalid input. What's your gender?"); 
var name = prompt("What's your name?",""); 
var greeting = (gender == "male" || gender == "m") ? "Sup dude." : "Sup girl."; 
alert("Hello, " + name + "! " + greeting); 

的错误，我得到：

Line: 5 
char: 1 
Object expected. 

我无法弄清楚。

Answer 1

两个问题：

1. 正如评论所说，W /使用cscript.exe脚本主机不支持，也不提示（），也没有警报（）
2. JScript中数组没有.IndexOf（）方法

你必须推出自己的：

function arrayContains(array, value){ 
    for (var i = 0, e = array.length; i < e; ++i) { 
     if (array[i] === value) { 
      return true; 
     } 
    } 
    return false; 
} 

function prompt(p) { 
    WScript.Stdout.Write(p + " > "); 
    return WScript.StdIn.ReadLine(); 
} 

function alert(s) { 
    WScript.Echo(s); 
} 

var possibleOptions = ["male", "female", "m", "f"]; 
var gender = prompt("What's your gender?",""); 
while(!arrayContains(possibleOptions, gender)) 
    gender = prompt("Invalid input. What's your gender?"); 
var name = prompt("What's your name?",""); 
var greeting = (gender == "male" || gender == "m") ? "Sup dude." : "Sup girl."; 
alert("Hello, " + name + "! " + greeting); 

输出（控制台）：

cscript 26073853.js 
What's your gender? > neuter 
Invalid input. What's your gender? > male 
What's your name? > tarzan 
Hello, tarzan! Sup dude. 

cscript 26073853.js 
What's your gender? > female 
What's your name? > jane 
Hello, jane! Sup girl.
