如果用户在 7 秒内没有给出答案，我只希望第二个超时函数运行。我尝试使用 clearTimeout()，但它无法识别我的 if 语句，并且每次都只是运行ning，无论用户是否及时回答。我尝试在

中使用它

if(result01[0]==='hspeaker'){alert('correct:'+result01);}

提前致谢。

将其存储在变量中并调用

clearTimeout(variableName)

有条件

const timeout = setTimeout(()=> console.log("timeout"),3000);

function stop(){
  clearTimeout(timeout);
  console.log("timeout stopped");
}

<button onclick="stop()">Stop Timeout</button>

function start(){
    alert('5 seconds')
    setTimeout(function(){
        bootbox.prompt({
            className:'questionOne',
            title: "type hspeaker", 
            centerVertical: true,
            callback: function(result){ 
                if(result===null){
                    alert("try again?");
                    bootbox.hideAll();
                    clearTimeout(outOfTime);
                    location.reload()
                }
                var bashed = /hspeaker/i; 
                if(result.match(bashed)===null){
                    alert('incorrect:Try again?');
                    clearTimeout(outOfTime);
                    location.reload();
                }
                var result01 = result.match(bashed);
                if(result01[0]==='hspeaker'){
                    alert('correct:'+result01);
                    clearTimeout(outOfTime);
                }                       
            }
        });

        const outOfTime = setTimeout(function(){
            alert("out of time")
        },7000);
    },5000);
}
