尝试在嵌套的if \ else语句中调用break

Question

这是我的代码的前面，我喜欢在＆＃34; else＆＃34;之后嵌入一个break语句。如果答案超过18

setTimeout(function(){
confirm("I am ready to play!");
age= prompt("What's your age?");
    if(age<18){
        alert('You are allow to play!');
    }
    else{
    alert("No!"); 
    };

Answer 1

break或continue只能在循环中使用。如果要停止执行函数代码，只需添加return;

setTimeout(function(){
if (!confirm("I am ready to play!")) return; // I suppose that's you really want.
age= prompt("What's your age?");
    if(age<18){
        alert('You are allow to play!');
    }
    else{
        alert("No!");
        return; // Stop the function.
    }
}, timer);

Answer 2

您需要返回退出函数而不是休息。如果需要，请检查是否为假，或者只是在那里写回来

setTimeout(function(){
confirm("I am ready to play!");
age= prompt("What's your age?");
    if(age<18){
        alert('You are allow to play!');
    }
    else{
return false;
    };
