【问题描述】：

我知道我正在编写的代码非常简单，但我尝试观看了很多教程并让这些代码在我的 JavaScript 代码中工作，但我似乎无法理解。尽快提供一些帮助会很有用。我试图将这段代码简化为一个循环，它假设询问用户有多少人参加聚会，而不是根据有多少人来询问客人姓名的后续问题。 gjester=客人

var gjester = prompt("How many is coming to your party?");
if (gjester == 1){
    var name1 = prompt("What is the name of guest 1?"); 
    console.log("Yey " + name1 + " is coming to your party")
}
if (gjester == 2){
    var name1 = prompt("What is the name of guest 1?");
    var name2 = prompt("What is the name of guest 2?");
    console.log("Yey " + name1 + " is coming to your party");
    console.log("Yey " + name2 + " is coming to your party")
}

//and so on//

【解决方案1】：

您可以像这样使用 do/while 循环：

var count = prompt("How many is coming to your party?");
var names = []
do {
    let name = prompt("What is the name of guest "  + count + "?");
    names.push(name);
    count--
} while (count > 0)

无限循环！。你忘了递减计数值。
哎呀，可能是 OPs 电脑坏了

【解决方案2】：

这可以用一个简单的for循环来解决

let gjester = prompt("How many is coming to your party?");

let names = []
for(let i = 0; i<gjester ; i++) {
   names.push(prompt(`What is the name of guest ${i+1}?`))
     console.log("Yey " + names[i] + " is coming to your party");
}
