你能告诉我这个javascript代码有什么问题吗？

Question

//确定年龄的人是> = 13还是陪伴

var age = prompt("How old are you")
var accompanied = prompt("Are you accompanied by an adult")

if (age >= 13 || accompanied == "Yes"){
    console.log("you may see the movie")
}else{
    console.log ("You can not see the movie")

Answer 1

检查以下代码段，

var age = Number(prompt("How old are you"));
var accompanied = prompt("Are you accompanied by an adult");

if (age >= 13 || accompanied == "Yes"){
    console.log("you may see the movie")
}else{
    console.log ("You can not see the movie")
    }

Answer 2

您的代码效果很好，但是您错过了一些分号;，并且忘记在}语句的最末端关闭一个大括号else。

虽然代码不需要分号，但您不应在不使用它们的情况下编写JavaScript代码：

• 分号是“干净”编程的好习惯
• 自动分号注入有时可能无效，因此丢失分号会导致意外行为

var age = prompt("How old are you");
var accompanied = prompt("Are you accompanied by an adult");

if (age >= 13 || accompanied == "Yes") {
  console.log("you may see the movie");
} else {
  console.log("You can not see the movie");
}
