javascript - 将 setTimeOut 属性添加到 div

Question

希望你们一切都好!

今天早上我正在重新创建一个关于石头剪刀布游戏的教程。我完成了所有编码，我想在其中添加一些额外的代码以使其看起来很棒。

我只是想知道如何将 setTimeOut 添加到除法结果中，以便让它在几秒钟后消失。

var user_score = 0;
var computer_score = 0;
var userScore_span = document.getElementById("user-score"); 
var computerScore_span =document.getElementById("computer-score");
var randomNumber;
var result= document.querySelector(".result");
var computer_choices;
var user_choices;
var paper_div = document.getElementById("p");
var scissors_div = document.getElementById("s");
var rock_div = document.getElementById("r");


function computerChoices(){
var choice = ["r","p","s"];
randomNumber = Math.floor(Math.random()*3);
return choice[randomNumber];
}
function returnW(letter){
if(letter === "r") return "rock";
if(letter === "s") return "scissors";
return "paper";
}

function win(userChoice,computerChoice){
 user_score++;
userScore_span.innerHTML=user_score;    
var subU = "user".fontsize(3).sub();
var subC = "computer".fontsize(3).sub();
document.getElementById(userChoice).classList.add("GreenBlur");
result.innerHTML="You win " + returnW(userChoice) + subU + " beats " + returnW(computerChoice) + subC;
setTimeout(function(){ document.getElementById(userChoice).classList.remove("GreenBlur")},1000);
}




function lose(userChoice,computerChoice){
 computer_score++;
computerScore_span.innerHTML=computer_score;
var subU = "user".fontsize(3).sub();
var subC = "computer".fontsize(3).sub();
document.getElementById(userChoice).classList.add("RedBlur");
result.innerHTML="You lose " + returnW(userChoice) + subU + " lose to " + returnW(computerChoice) + subC;
setTimeout(function(){ document.getElementById(userChoice).classList.remove("RedBlur")},1000);
}





function draw(userChoice,computerChoice){
document.getElementById(userChoice).classList.add("YellowBlur");
result.innerHTML="It's a Draw!";
setTimeout(function(){ document.getElementById(userChoice).classList.remove("YellowBlur")},1000);
}



function game(userChoice){
var computerChoice = computerChoices();
switch(userChoice + computerChoice){
case "rs":
case "sp":
case "pr":
win(userChoice,computerChoice);
break;
case "sr":
case "ps":
case "rp":
lose(userChoice,computerChoice);
break;
case "rr":
case "ss":
case "pp":
draw(userChoice,computerChoice);
break;

}
}







function main(){
paper_div.addEventListener("click", function(){
game("p");
})

scissors_div.addEventListener("click", function(){
game("s");
})

rock_div.addEventListener("click", function(){
game("r");  
})
}
main();

添加

document.getElementsByClassName("result")[0].innerHTML = "";

也在每个 settimeout 中。

var user_score = 0;
var computer_score = 0;
